Academy Entrance Arc
Boruto and Sumire are classmates, who study and train under Shino. Sumire, as the class president, watches over and cares about her class's safety. Later, when Boruto was allowed to return to the Academy after 2 weeks suspension, Sumire commented that Boruto always stands out when he tried to take Shikadai's textbook from him, forgetting to get his own book. When Inojin rejected Boruto's friendship request, Sumire was bothered and shyly tells Inojin to stop criticizing Boruto's position as the Hokage's son, telling him later to have a good relationship between classmates.
After that, Boruto wins a fight against Iwabe and Sumire when they leave, smiles for his victory. Returning to class, Sumire is relieved that everything went well for Boruto, and Chōchō, noticing that, asks her why she's so concerned about Boruto. The question makes Sumire blush and she gives the excuse that she's the class representative.
Because Boruto smashes his father's Hokage stone face, he is sent with his classmates to help to carve the monument back to its original form. Sumire says that it's an honor to help with the Hokage Monument and says she likes manual labor. Hearing that, Boruto compliments her saying that she's worthy of her role as a delegate.
Later, Boruto took a break with his friends, playing video games. When Sumire notices that their break lasted too long and tells them to return to work, Boruto obeyed her without any arguments. Metal Lee, continuing to carve, ruins the whole job due to nervousness and breaks Naruto's rock face another time and the mass of rocks destroys a quarter of the scaffolding. Boruto, remembering that Sumire is alone on the floor above, worries about her and asks if she's alright. She then answers she's alright.
Shortly after, Sumire, Chocho and Sarada were being followed by Magire, who seemed to have a crush on Sumire. Not only because Magire stalks Sumire, but also because he's so bold in confessing his feelings for her. Sumire hid behind Boruto, scared, holding his shoulders tightly. When Magire was about to leave the place, Boruto prevents Magire from escaping and Cho-Cho points to him saying that he should confess his feelings, which caused Boruto to blush and panic as well, thinking that he was the one who was asked to confess. When Magire proposed her, Boruto got shocked and jealous, hugging Mitsuki with his face completely red, snot coming from his nose and steam above his head.
Sumire politely rejects him and Magire flees. The next day, Magire left creepy confession messages for Sumire all over the Academy, prompting the boys and the girls to look after her. The girls and the boys were walking but soon were seperated by a metal wall which caused Boruto to hit the wall repeatedly, in an attempt to break it and worriedly asked Sumire if she was alright. The girls hid inside the storm room. When Sumire made it outside the room, the door was slammed close by an invisible Magire, seperating her from Sarada and Chocho, scaring her. Denki came towards Sumire, but was knocked out by Magire. Now possessed by the dark aura, he whisked her away. Boruto rushed towards Sarada and Chocho, asking where Sumire is and shortly, heard Sumire's scream from the school terrace. Boruto and his friends worriedly rushed towards the terrace.
They went up to see Magire trying to get close to Sumire. Magire threatened everyone to stay away from them, wanting to be alone with Sumire. Boruto, walked towards Magire and agreed to take him on, much to Sumire's relief. Magire turned invisible, and Boruto, along with Shikadai jumped in without any plan, annoying Sarada. Chocho, seeing the both of them struggling with Magire, yelled loudly and criticizes Magire's idea of trying to win Sumire's heart in a very creepy way. Magire was rescued from the dark aura and realized his mistake and apologized to Sumire, who forgived him right away. Boruto was lost in some trance and Sumire broke his trance, asking what's the problem. Boruto quickly replied in negative, and they left the place, with Mitsuki remarking that no problem has occured for now.
Shino assigned the class to visit several workplaces, to get experience. When Boruto learns that Sumire is in a hostage situation in the Water Purification Plant, he rushes to save her. Shikadai tells Boruto that they aren't sure that is the Class Rep's team which is in danger because Boruto is never shown telling Shikadai or Mitsuki that he saw the Class Rep in the Water Purification Plant yet Shikadai assumed that Sumire was the reason Boruto was acting like that. After learning her team is unharmed but Sumire is left hospitalized, Boruto rushed to the hospital. Inside the suite, Shino felt guilty for suggesting such an activity and others asked where Boruto was. Metal Lee, leaned against the suite door, saying that the Class Rep can rest properly without Boruto and the others around. At the same time, Boruto slammed open the door, causing Metal Lee to lose balance and ultimately fall down. He rushed towards Sumire worriedly and enquires if she was alright. Despite Sumire telling that she was alright and Metal Lee painfully said that he wasn't alright, he still paid no attention to him and focused on Sumire. He adamantly apologizes for not being there for her when she was attacked. Sumire politely says she doesn't blame him for what happened. He kept repeatedly apologizing and Wasabi told him that he is scaring her, which he denies but was taken away by Sarada, outside the suite. He was sitting outside the suite gloomily, despite Shikadai telling that it is not his fault.
When Inojin remarked that Sumire is the most affected whenever Boruto causes trouble, Mitsuki did feel that was right and visited Sumire in the hospital, alone. Mitsuki asked her feelings on Boruto, she replied that Boruto did cause a lot of trouble but it's a lot of fun around him always. Mitsuki enquired about her family, to which she replied that she has none, and asked Mitsuki the same.
After visiting her in the hospital, he went to Boruto's house, only to end the dinner in a bad note as Naruto left the dinner midway, when he sensed a problem. Boruto was furious, and vowed that he won't sacrifice the people close to him.
Mitsuki tells Boruto that Sumire is the culprit behind the incidents, a fact Mitsuki has known all along. Despite Mitsuki's explanation of Sumire having interacted with each victim, Boruto is not convinced of her guilt. Boruto adamantly refuses to believe it but wants to confront Sumire on the matter. When Nue is released by Sumire and begins attacking the village, Boruto attempts to rush to the scene to find Sumire but is held back by Mitsuki, who reveals his mission to kill Sumire. Mitsuki told Boruto that the person who casts the jutsu must die, meaning Sumire should die, which horrified Boruto. When being asked by Mitsuki if he would choose to save the village or Sumire, Boruto chose both without any hesitation, which caused Mitsuki to constrain Boruto with his clone and left to kill Sumire, which terrified Boruto. He yelled his name to stop him, but to no avail. Boruto manages to knock the snake down by one of his clones using Gale palm, which caused his clone to hit him as well. He activates his eye and was able to track her through a chakra trail.
He quickly rushed off to save Sumire from Mitsuki. When Boruto saw Mitsuki pinning Sumire down to the ground with his leg, ready to kill her, Boruto ordered him to leave her and she got out of Mitsuki's hold. When Boruto asks her if she is the culprit, she admits the truth, explaining it was her mission to collect chakra from people and harvest it for Nue so she can carry out her father's wish to destroy Konoha out of revenge, which shocked him. She further elaborates that the Sumire he knew never existed. Boruto stops Sumire and Mitsuki from killing each other and his eye starts spakling and began acting wildly. When Nue was running out of chakra, Sumire offered her own chakra to him, which caused Nue to grab her and take her into his dimension. A horrified Boruto chases after her into the dimension, without even thinking twice.
When he was inside the dimesion and began searching for her, Nue jumped in and Boruto thought that Nue killed Sumire and was ready to avenge her, but was relieved when Mitsuki told that she was still alive. Boruto asks her to come back with him, which baffled her. Sumire tells him and Mitsuki her past of being taught by her father to seek revenge against the village. After a few fights between Boruto and Mitsuki vs Nue, Mitsuki says that the Gozu Tenno behind her back is valuable and doesn't care if she is killed when it is extracted. When they ran towards each other in an intention to kill one another, Boruto put his own body infront of them, causing Sumire's kunai to hit his right arm. Despite Mitsuki repeatedly telling that Sumire is the culprit he was still unconvinced that Sumire truly faked all her concern for her class mates since meeting her. Mitsuki is surprised by Boruto and adds Sumire did mention wanting to end things quickly while in the hospital.
Boruto sees the dark chakra on her disappearing and tells Sumire that she will be able to choose her own path, which makes her slowly realize who she really is. Soon enough, Boruto freed her from her negative emotions and the Gozu Tenno on her back shatters into pieces, causing her to fall down on the floor due to the drain of her negative emotions. Mitsuki and Boruto rush to escape the dimension that was currently breaking down. Boruto yelled at her, asking her to come with him, but didn't receive any response. Mitsuki took him away, which made Boruto yell her name. Sumire has visions of her mom speaking with her and combing her hair. She gasps and sees Boruto standing beside her. Sumire looks up at him tearfully and asks him why he came back to save her, he lends her a hand and looks down at her smiling, telling her that he wouldn't leave her behind. This leaves Sumire in tears. She stretched her hand, which Boruto grabbed and they sat on Nue and rushed out of the dimension. When Nue stays back, Sumire tries to go back for the beast, worried. Boruto stops her by grabbing her waist and she grimly abandons Nue.
After they came out of Nue's dimension, Boruto and Sumire fell on the ground together, and she ended up falling on top of him. Soon, Konoha shinobi along with Sai surrounded them. Sai, who could feel Sumire's pain due to having a similar past like him, offers to take care of her. A little while later as they go back to the Leaf Village, Sumire was leaving to talk to Sai who assured others that she won't be harmed. As she leaves, Boruto activates his eye and sees a small ghost wrapped around her left hand. He calls out to her, saying: "He's still there! It's faint, but it's wrapped around your left hand." Sumire unwraps her bandage and sees a small red eye in the center of her left palm, which allows Nue to see through there, meaning she is back with Nue.
Sumire is absent from school for several weeks due to weak physical health and Boruto can only think about her, wondering where she is. Shikadai and Inojin note she committed treason against the village and will have to remain in custody indefinitely. Boruto refuses to believe Sumire did anything wrong on her own will. He comes home and requests Naruto to let her free and also let her return to the academy, who tells Boruto he won't let her down and warns Boruto to stay out of adult situations, much to Boruto's dismay. When Hinata realizes that her son was in a serious conversation with her father, she realizes that Sumire is someone very important to Boruto because it was the first serious argument between the two. She calls Himawari to the kitchen to let Naruto and Boruto talk without any disturbance.
The next day, Shino informs his students they'll be assembled in new three-person teams to see how well they fit with each ofter graduation. Boruto and Mitsuki lacked a third member and Mitsuki wished Sumire was there in their group, which made Boruto shush him, as others don't know about her involvement in the incident. After completing, and winning the activity, Boruto asks where Shino has gone. Being told by Inojin that Sumire may be transferred to a different Academy or even another village and with others also wondering where she is, Boruto and begins to worry and tries to rush off to find her, protesting that; "While we're wasting time here, the Class Rep might-" (he was cut off by the arrival of Shino at the gates.) All of them were staring at him, without uttering anything. Shortly, Sumire slowly made it towards the school entrance and softly told the others that she is back. Boruto was delighted and was about to rush forward to greet her but was blocked by everyone else, who rushed forward to greet her. He stays back from the crowd but, seeing her staring at him, he returns her gaze before giving his signature grin and a thumbs up, causing her to cry with happiness.

Sumire smiles at him and tells that people fear unfamiliar powers and despite that, he accepted her. Sumire informs Boruto saying that soon she will transfer to the Headquarters at Konoha as Katasuke's assistant. Boruto was delighted, and asked her if she will return to the village to which she nodded happily and also promised to work hard in order to support the village. As Team 7 prepare to leave the lab to find a missing Konohamaru and Mugino, Sumire comments to Sarada how Akita has taken a liking to Boruto and asks Sarada if Boruto is popular amongst girls. Later Sumire asks Sarada if it bothers her to see Boruto with other girls, Sarada clearly states that it doesn't effect her. But, Sumire said that it does bother her which left Sarada shocked at her bold statement. Sumire asked her to take care of Boruto and the others, and happily waved him goodbye.
Team 7 brought Kawaki to the Scientific lab at Ryutan post battle with Garou to examine him. Boruto, Sumire and Mitsuki went to the room where Kawaki was confined with some food. Sumire handed him the food, which Kawaki jerked away angrily, causing her to almost fall but ended up falling on Mitsuki's chest, who held her. Boruto got mad and swiftly grabbed Kawaki's collar and lashed out at him for doing that to her. Sumire looked at Kawaki and Boruto fighting worriedly, and she explained to Kawaki that she has no intention of harming him. He sqeezed Kawaki's should in anger and Kawaki winced. Mitsuki immediately told Boruto to stop doing so as he is just recovering and the pain might be unbearable. Boruto apologized, for losing control.
After Kawaki and Sumire's fight, Kawaki escaped with a heavily injured right arm, caused by Nue. Sumire decided to follow him. Boruto on the other hand, was worried for her as he clearly knew that he is very dangerous and way stronger than her. As Sumire followed and spoke softly to Kawaki after she found him, she saw his dizzy nature and offered a nutrient supplying syringe. She was about to inject him but Kawaki swiftly grabbed her neck and pinned her against a fence, strangling her. Despite Sumire painfully telling that she has no intention of harming him, he didn't let her go and continued choking her. Boruto saw this, and angrily yelled at Kawaki to let go of her. Konoha policemen surrounded him and started firing at Kawaki. Kawaki managed to escape, but Sumire fell unconcious. Boruto rushed towards her and asked Mitsuki and Sarada to go ahead and pursue Kawaki. He quickly made her stand, and held her hand, putting it around his shoulder and put his other arm around her waist, to support her. Holding her, he slowly approached the Ryutan station entrance, asking Sumire to wake up quickly. Naruto and Sai rushed towards Boruto, and saw Sumire unconcious. He quickly let go of her and put his arm around her shoulder. Sumire woke up, and Boruto was relieved and asks if she was fine. Sumire explained to Naruto about Kawaki saying that he didn't want to rampage because he wanted to and also explained that he had an immensely sad face. But Boruto was still angry with him for strangling her. But Sumire told that he was just like her.
Much later, Boruto, Sumire and Kawaki watch Amado being interrogated by Naruto, Shikamaru and Sasuke, through a glass wall. When Amado was talking about Karma, Boruto looked at his mark and Sumire looked at him worriedly, sad with the fact that Boruto might eventually become Momoshiki Otsutsuki.
When Amado also told that killing Boruto is the only option to avoid the rebirth of Momoshiki, Sumire was visibly horrified. With Amado further telling more about the high chances of Boruto's death, or even becoming Momoshiki for that matter, Sumire became even more worried.
Post Kawaki's collapse, Kawaki, Sumire, Shikamaru, Katasuke and Amado went towards a basement, which was made up for hiding from attacks.
As Boruto was fighting Isshiki, Sumire was horrified to hear that Boruto was in danger of becoming transformed into an Ōtsutsuki through his Kāma. She also feared for Boruto when she learned he had gone to fight Isshiki along Naruto and Sasuke, but Amado assured her that Boruto's contribution to the fight, though not in power, was invaluable.
Sumire, Katasuke and Shikamaru were eagerly waiting for the arrival of Boruto and the others. Soon, Shikamaru got a news from the sensory team saying that Boruto, as well as the others are safe, which left Sumire relieved and happy.
After they returned, Sumire can be seen treating Kawaki. As she treats him, she assures him that he will not need to worry much from now and also told shyly that as he hangs out a lot with Boruto, she can learn and know more about him, blushing simultaneously. Kawaki looked at her and bluntly asks her if she likes Boruto which caught her off guard. She dropped the syringe she was holding in shock and panic, and blushed even harder, requesting Kawaki to stop saying that so bluntly and also pleaded to keep this secret between the two of them. Katasuke laughed, and told that her crush on Boruto was so obviously known to everyone.
Later, Amado and she jointly took care of Kawaki and she was growing suspicious of Amado's true intentions. She also confessed to have been really worried about both Kawaki and Boruto, which resulted in Amado asking her if she really is smart or stupid.
