Shusei likes to tease Hotsuma and avoids giving straight answers through this method, whereas he is usually silent or smiling when confronted by other people. Although he seems popular at school and generally liked by the Zweilt Guardians, he maintains a formal nature designed to conceal how he actually feels and thinks. He never shows negative feelings if he can help it, and keeps how increasingly hopeless he feels from Hotsuma about his situation. His reticence is self-harming and he grows more and more melancholy, to the point where other Zweilts and members of the Giou clan are often heard asking if he is well.
When it is later revealed that Hotsuma knows the true reason why Shusei lost to the Opast Ashley, Shusei reacts with open surprise and admits that he honestly wanted to die and that living on is something he can no longer do. This quiet admission helps his partner to understand how hurt Shusei has been feeling for a while and how far Shusei would go to ensure his partner's happiness over his own. After restoring their friendship, Shusei learns the importance of sharing how he feels and how to trust his partner more.
During the manga, and even the anime, there are hints that Tsukumo wants to be friends with him, but Shusei seems to be consistently distant, treating Tsukumo in a polite, pleasant manner which eventually lifts towards the end of the series. Here, Shusei is seen accepting an ice cream from Tsukumo in Twilight Mansion and promising to spend more time with the younger Zweilt.
Shusei is a young man with brown hair and golden eyes.He is frequently seen in smart casual clothes during his role with the police and tends to wear more outfits when resting in Twilight Mansion. Like Tooko, he wears the red tie denoting a second-year student at the school they attend.While the cast are all slim, Shusei is observed as being "frail" compared to the others and serves a defensive purpose in battle, with physical actions restricted to casting spells through crystal spheres and wielding two blades named "Kurai Kurou".
Due to his looks, he instantly gains the admiration of Opast Ashley, a fan of "pretty boys", and has this 'untouchable' quality which sets him apart from other people.
Shusei is Hotsuma's childhood friend and greatly admired by his partner for his individual brilliance. He seems to have played the piano from an early age, now acting as a member of the student council in addition to performing 'clairvoyant' duties for the local police and fighting for the Giou clan. However, he is modest about his strengths and achievements, mainly concerned with his partner's welfare. In the manga, it is said that Shusei was a girl in a previous life and Hotsuma and she were a married couple.
He never left Hotsuma's side, even when the boy was isolated from others at school, and appeared just in time to persuade when Hotsuma tried to burn himself to death. This event caused the indelible scars on Shusei's body, making Hotsuma realise how dangerous it is to wield God's Voice. While Shusei never regrets saving his partner's life, what becomes unbearable for him over time is the look on Hotsuma's face every time he sees the scars.
Although his background is never revealed much in the anime, in the manga he is seen as a burden to his parents, overhearing them discuss the fact that he was never wanted, simply born due to expectations his
parents felt had to be fulfilled.
His relationship with Hotsuma has a strong bond and he trusts Hotsuma with his life. Both of them are very close to eachother and it is shown that they would rather die then not be able to be with eachother. In the manga, when the Zweilts are talking about the low number of guardians, Hotsuma mentions that he and Shusei have tried to have a child in their past life, as Shusei was a girl in his past life. Hotsuma is also seen to be quite protective of Shusei and when he is taken by Ashley, Hotsuma seems to be extremely upset and angry.
Shusei seems to be distant to Tsukumo but near the the end the manga/anime Tsukumo is seen giving Shusei an ice-cream. This could suggest that they become friends later on since Shusei says that he would like to spend more time with him.
For a while, Shuusei is seen to ignore or avoid Yuki's company in favour of Hotsuma. He seems to do this out of consideration for his partner's feelings towards God's Light, though it is later revealed that Yuki is a source of pain for Shuusei as well, especially when Hotsuma's temper is calmed by Yuki. After recovering from his ordeal with the Opast named Ashley, Shuusei approaches Yuki openly for the first time and offers to protect and service God's Light in future, even kneeling down to emphasise his sincerity, much to Yuki's embarrassment.
During a week long class trip with only Toko and Shuusei, Toko tells Shuusei about the rumors about the two of them of being a couple, Shuusei asks Tooko if she wants to be his bride. Later, he lets her escape from the unknown creature claiming she had a better chance and that he wouldn't 'go down withought a fight'.
