Kazuki Koyama♂

Orphaned as a result of the accident, he was adopted by his aunt. Aloof, quiet and cool when dealing with others, he doesn’t like “loud people” like Akito and Aki. An above-average intellect and clever disposition make him an ideal candidate for IGRASIL. Although the duties of the organization require him to work in a team, Kazuki prefers acting alone and does not like to get involved in things that do not concern him.
Despite the desire to avenge the death of his parents, he is curious as to why the mysterious perpetrator saved his life, and why he keeps appearing in his dreams.
