Natsume has orange hair that falls just above his violet eyes. Like Tsubaki and Azusa he also has a beauty mark, but his is placed below his lip. He is always seen wearing his favorite attire, a casual black suit jacket, white shirt with a green checkered necktie.And
In Season 2 he changes into black trousers with a white shirt, light green v-neck and a blue tie. He also has a black watch like Season 1
Natsume has a blunt way of talking, but greatly encourages other people. He is very strict when it comes to problems and will willingly help to resolve it. He is rather calm and would protect his siblings. Of the brothers, Natsume is probably the most experienced in being trapped by the past, since his past actions ruined his relationships with his brothers; he appreciates and respects the affects that all present actions have, knows the hardships of past ones, and understands that the best anyone can do is move forward. These lessons are what he tries so very hard to teach to his siblings, with minimal, but still moderate, success.
Like his brothers, he also holds an ever-growing, unconditional love towards Ema. He respects her and her feelings, and is willing to wait for the day that she can see him as a man in love, and not just her older brother. Of all the brothers, Ema herself says that Natsume understands her the best.
In the manga, it is revealed that Natsume has had a low regard for himself ever since he quit sports, mainly because it destroyed his bond with Subaru, and also damaged his relationships with his other brothers. Since then, he convinced himself that he was the least of the siblings, not just in carrier success but overall character. He was never jealous of them though, not until Ema came into their lives and turned the whole family on its collective head. He has blamed himself for being "half-hearted" in everything for a long time, and it was Ema's entrance into his life that made him realize that there are somethings in this world that one just couldn't afford to give up on, no matter how hard or how long they had to be fought for. It was her caring and thoughtful nature that caught his eye, and it was her that made him feel more comfortable admits the tense atmosphere when he was around his brothers due to his past failures. Falling in love with her reignited his fire, and now he presents himself as a determined, calm, and patient man who is willing to wait as long as it takes to be with the woman he loves.
In Natsume's early life, he was very athletic and because of this he got close to Subaru. Subaru looked up to Natsume a lot until Natsume realized sports could not give him a better future and quit. He explains that even if he had continued, he would be doing it half-heartedly. This was the root of Subaru's hate for Natsume. Although he had quit, he still continues to give Subaru advices and watch his matches.
The day of the wedding Louis does Ema's hair and she puts on the dress her stepmother and father got for her, and when she walks into the chapel she meets Natsume. Ema then finds out that Natsume is the triplet brother of Azusa and Tsubaki and that he works at one of her favorite game company, and he offers to give her samples of the new games if she wants. He also asks how Subaru is doing but she told him that she doesn't know, but then Natsume receives a business call.
Since there are no more ingredients for dinner and very few people were able to make it home, Tsubaki suggests eating out instead. They also contact Natsume and Subaru to join them once they are done with their activities. Natsume arrives just before Ema goes off to buy drinks, Subaru then arrives and meet her on the road. Wataru begins talking to a duck along the pond, seeming dangerously too close to the edge. Natsume rushes over to grab him, but just as he lunges, Wataru trips backwards and Natsume is sent flying into the pond. They decide to go home and Natsume takes a shower.He decides to stay home for a while, still curious over the connection between Subaru and Ema.
Ema decides to go to Subaru's basketball game, despite Juli's protests, where she meets Natsume. Natsume offers her a ride after the game since it begins to rain, but gets a phone call and leaves for a bit. Subaru rushes over despite having another game later on and confesses that he hopes that she can be at his side forever. Natsume reappears and angrily scolds Subaru for not staying with his team for the next game. Subaru leaves and Ema goes home with Natsume.
In Episode 9, Ema, depressed finding out that she is adopted, thinks that she is an outsider and she decides not to go back to the mansion. Worried that Ema didn't come back to the mansion and won't pick up her phone, Natsume finds her, he asks her to go back to the mansion because everyone is worried about her, but she refuses to go back so he takes her to his apartment. There she tells him about her identity, feeling sad that Natsume can't understand how she feels as he is not adopted, she decides to go back to go samrer sels, but then Natsume pulls her by her arm and hugs her saying that she is not an unneeded person and then kisses her. He asks her to stay over at his apartment as its too late to return and she agrees.
In Episode 10, Kaname invites everyone to his buddah club event in which he is the host. Everyone agrees but only Natsume, Ema, Ukyou, Masaomi, Azusa, Hikaru and Wataru were able to go as the rest of the brothers are busy. On their way, Hikaru asks Ema if anything happened in Natsume's apartment when she stayed over, which makes Natsume spill his drink, saying nothing happened as they are siblings and Ema agrees. Hikaru then asks another question to Ema, this time about what happened between Azusa and her. Upon hearing Hikaru's question, Azusa accidentally hits the drivers wheel causing the car to change its direction. Ukyou then comments that the car behind seems to be very lively.
After the surprise party the Asahina brothers threw for Ema and Yuusuke, Ema sees Natsume standing in balcony she reaches to talk to him and tells him that she decided not to date anyone as she thinks of them as family and she can't choose one of them and tells him she feels bad because so much happened between the siblings because of her but he says she was just being nice to them and he can understand her. When Ema was about to leave, Natsume stops and tells her that he can understand her but he can't suppress his feelings, kissing her, and says sorry for being a brother like that and leaves.
RelationshipsEdit Later he apologized to Ema for the misunderstanding and gave her his company card so she can contact him if she's in trouble. He was surprised to find out Ema is a fan of the games his company makes. After a few days, Ema meets Natsume at a restaurant for game instructions, where people confuse them for a couple. Later on their way home he gives her his scarf as a Christmas present. In a more recent episode, Natsume tells Ema that he is dazed over her and his feelings are not halfhearted after kissing her. He is not forceful with Ema and respects her decisions. That's why Ema states that he understands her the most. In the manga, Ema and Natsume confess to each other during hers and Yuusuke's graduation party and share a kiss on the balcony. Natsume asks Ema to move in with him. At the end of the novels, however, Ema chooses Subaru instead and tries to return Natsume's keys to him as a sign. Still, in the manga, Ema chooses Natsume, and it is hinted that they will marry in the future. This is later confirmed when Juli becomes angry about their wedding preparations.
Subaru and Natsume were on very good terms with each other until Natsume quit running. Subaru looked up to him and due to him he wanted to become a profession basketball player but Subaru was really angry when he quit. It is shown that Natsume still cares for him but Subaru tells him that he doesn't want advice from someone who quit in the middle. The reason Natsume quit running was because he realized he cannot have a good future as an athlete and can't earn much money. At the end of anime, Subaru apologizes to Natsume for punching him, he forgives him and they get back on good terms again.
