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.
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. Like his brothers he is also in love with Ema.
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 the mansion, 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.

In 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.
