Yabuki Eishirou (夜吹 英士郎), also known as Eishirou (影四郎), is a student of Seidoukan Academy. He is also a member of the Kageboshi (Shadow Stars). He also worked freelance until Claudia Enfield forced him to be her personal spy.

Appearance

Eishirou is described as being lean and a head taller than Ayato. He also has a noticeable scar on his left cheek. Under the uniform jacket of Seidoukan Academy, he wears a green hoodie and gray trousers. Eishirou has light brown hair that is almost messy in appearance.

Personality

Eishirou is very cheerful and outgoing to those around him, but can turn very serious. He is also mysterious hiding his true abilties and spywork. That being said he's also helpful to Ayato.

Abilities

Genestellar (星脈世代): As a Genestellar, Eishirou has enhanced physical ability and an aura known as prana.

As a descendent of a clan of intelligence agents, he is adept at spycraft and intelligence gathering, even with his young age.

He's strong enough to take down Wernher of Grimalkin (Rewolf's intelligence unit) easily.

Relationships

Amagiri Ayato

Eishirou and Ayato are good friends and roommates, with the former acting as the latter's informant (usually in exchange for food). Ayato is unaware of Yabuki spy talents.

Claudia Enfield

He is shown to be a personal agent of Claudia, and she seems to have a high regard for his abilities and discretion using him to interrogate Silas and as part of her plans. They have a good rapport, as evidenced in their phone call in Liseltania when she informs him of the situation.

Trivia

• Eishirou has access to a lot of classified information due to being member of the Kageboshi. His job at the First Newspaper Club disguises his other, more clandestine activities.
• According to Lester, Eishirou apparently has a girlfriend named Mikizawa Midori (水城澤 翠), who is the head of the First Newspaper Club which he is a member of. Randy had witnessed her giving Eishirou a hand knitted sweater as a Christmas present the year before.
