The manga frequently depicts a rivalry between brothers as a reoccurring motif. The Brothers Conflict is a wonderful illustration of this. Wataru, Yusuke, and Tsubaki, the brothers, begin the game by competing to see who can get the lowest score. They try to outscore each other, but the game is won by the one with the lowest score. This problem recurs frequently, and it is one of the manga’s most aggravating parts.
Ema is featured in the Brother’s Conflict Gimme Love special. Ema’s beauty has been admired by a boy who resides on the 2F Sunrise Residence. Louis informs the other brothers that Ema and Louis are dating. The two boys start to form feelings for one another. Ema continues to fall in love with the other brothers despite the fact that they are at odds. She even persuades her brother to let her stay with him.
The beginning of the brothers’ feud is also depicted in this episode. Ema fights Tsubaki, a member of the Aoi family, in the second episode. Then there’s a brawl in which both brothers are at fault. Tsubaki and Ema are feuding over a young lady named Azusa. Both Ema and Tsubaki are at blame for the disaster, and Tsubaki accuses Azusa of being to blame as well.
Ema’s next episode sets the stage. Ema is still healing, but her and Subaru’s friendship is causing a squabble among the brothers. Subaru tells Ema that he is the only one who knows her while the two men debate about who should get more attention. Ema feels embarrassed by Subaru’s actions in the second episode and wants to break up with him. When Ema comes up at Subaru’s sporting event, though, he is taken aback.
Wataru’s first appearance in the novel and anime differs significantly from his debut in the book. Wataru runs into Ema by chance by the Sunrise Residence’s gate. He then identifies himself and apologises, but she doesn’t see him again for a while. He phones her later at a mall arcade and tells her to call him Wataru-kun.
Wataru’s mother, Masaomi, was at a business conference a few days later and was rushing her son home. Meanwhile, the brothers were conducting errands for Wataru. Wataru collapsed on the soccer pitch, unconscious and with a high fever. The Asahina brothers, who had been assisting his mother with his sick brothers, returned home as well.
Yusuke is the Asahina family’s eighth son. He has a pious demeanour and despises mathematics. He also has a sweet tooth for children and keeps candy in his pocket. His younger brothers and sister, Ema, all have feelings for him. These feelings are returned, and he makes an effort to gain their attention. Despite the fact that this appears to be a poor scenario for the siblings, he continues to assist Ema and her younger brothers.
Yuusuke has been in love with his stepsister Ema since his freshman year as the twelfth member of the Asahina household. He is hesitant to accept her into his family at first, and he finds it difficult to eat the cake she makes for Subaru’s birthday. Despite this, he secretly sees becoming a member of the family as a way to get closer to her. Yuusuke’s yearning for her grows greater despite his efforts to control his feelings, and he falls even deeper in love with her.
Yusuke is a senior high school classmate of Ema when the series begins. He is a good soccer player, but he despises arithmetic. Because to his mischievous habits, he frequently fights Fuuto. Yusuke had a crush on Ema even before she became his sister, and he refused to recognise her as her sister. He is also envious of the Asahina brothers and wishes to eliminate them for good.
Tsubaki is the second oldest of the Asahina family’s six sons. He owns his own apartment and works for a video game firm. He used to be a highly athletic young man, but he gave up athletics in favour of a more solid employment. He also has two cats named Tsubaki and Azusa and is madly in love with Ema. Tsubaki and Ema are nearly inseparable, and their relationship is marked by a variety of conflicting characteristics.
The twins are shown in the same scene as Azusa and Tsubaki in the first episode of Tsubaki and Setsubou in Brothers Conflicts. Tsubaki feels envious of his twin brother’s improved behaviour. He tries to persuade Ema that his kiss was genuine, but she rejects him. Tsubaki then cuts her off, claiming that seeing his own bite mark on her face upsets him. Tsubaki kisses Ema and adds that when he leaned in to kiss her, he meant every word. Azusa intervenes at the end of the scenario, but Tsubaki continues to kiss Ema, which was not his intention.
Tsubaki and Setsubou start kissing later. Tsubaki is smitten by the attractive young lady and asks her to kiss him. Tsubaki kisses her again till she relents, but she refuses. Tsubaki and Setsubou go to bed together after this incident. Azusa feels upset as the kiss lasts for a long time.
Tsubaki, the Asahina family’s second son, is a lawyer who serves as a mother figure to the brothers. He is also a voice actor who works in the industry. He is less assertive and tenacious than Tsubaki, and he believes he is overly reliant on him. Tsubaki expresses his emotions for Ema in episode eight.
The confrontation between Azusa and the Setsubou brothers is one of the manga’s most famous scenes. Tsubaki and Azusa, two twins, are the focus of this series. Both are voice performers, yet it appears that the twins share an unbreakable bond. Ema finally persuades the twins to see their relatives after various misunderstandings and contradicting memories.
Azusa is the more caring of the two twins, and she frequently puts others before herself. In one episode, he tries to impress his sister Ema by forcing her to attend his voice acting audition with him. Tsubaki will intervene and stop him from smothering Ema. Azusa is shy around her and once kissed a bowl in front of her by accident.
The other episode begins with Tsubaki and Azusa debating the baby’s fate. Azusa is comatose in the hospital, but physicians are able to identify meningitis. Azusa is then scheduled to see his doctor, where Tsubaki informs him that his sickness is not life-threatening and that treatment will improve his chances of recovery. After that, Tsubaki and Ema go to the hospital. Tsubaki tries to kiss Ema after his appointment, but Azusa catches him and pushes him away.
Yusuke, the Asahina family’s fourth son, is another important character in the manga. Yusuke is an excellent soccer player, but he despises arithmetic. He is intelligent and adores Ema, but he isn’t pleased when she transforms into his sister. In reality, before she became Ema’s sister, he had a huge crush on her. Despite his protective nature toward her, he refuses to accept her, leading to a series of disputes.
Natsume is the name of the main male protagonist in Natsume and Setsubou: Brothers Conflict. His character is likeable since he cares for and is not jealous of his younger brothers and sisters.
Ema and Natsume meet for the first time at their parents’ wedding, at the chapel. Natsume believes Ema is an outsider and wishes to spend the rest of her life with her. Natsume, on the other hand, is sympathetic to Ema’s feelings and gives her a business card. He also expresses his desire for Ema to remain with him indefinitely. Ema accepts his apologies and follows him home.
Kaori is the stepmother to the Asahina brothers, in addition to Natsume and Setsubou. Natsume used to be close to her, but now that he had retired from basketball, he despised his decision. Subaru is nervous around Ema and doesn’t understand her because he doesn’t understand girls. He does, however, ask her out in episode five.
