Inukai

A first-year high school student and former member of the "Danjou Boxing Club," he appeared in Shibuya, desiring to fight Kaname Sudō after Kaname defeated Shuka Karino. He is fundamentally a good person, offering various pieces of advice to the inexperienced Kaname before their battle. He is reluctant to use weapons and prefers to fight using only his own body.

Jealous of Kaname's rapid growth, he challenged Kaname to a private fight without Danjou's permission, resulting in his expulsion from the Danjou Boxing Club. Afterward, he joined the "Sunset Ravens." However, after transferring, Liu Xuelan bluntly told him he had no innate talent for unarmed combat, leading him to abandon his policy and begin training with a three-section staff, which complemented his Sigil.

His Sigil is "Speed Star," which allows him to multiply his movement speed several times over. However, since his physical durability does not increase, there is a risk of injuring his own limbs if he strikes while accelerated. Additionally, he cannot accelerate while carrying heavy objects, so he is unable to wield weapons heavier than a knife.
