Characters
191cm / 28 years old
The youngest Captain of the EX-Class Response Unit. Calm and gentle. Airheaded, but terrifying when angry. He became interested in Guest after hearing they defeated an A-Class Apparition solo. He is cautious because he could find almost no background information on Guest, but he values their skill above all else. He has tried to recruit Guest several times but is rejected every time. His recruitment methods are unique, such as inexplicably handing Guest a jack-in-the-box.
Weapon: Katana Appearance: Blonde hair, center-parted, black eyes

Vice-Captain of the EX-Class Response Unit. Taciturn and sharp-tongued, but a battle maniac. He is actually quite caring and is slightly worried about Guest's health.

Weapon: Knives Appearance: Green hair, long nape, red eyes
190cm / 27 years old
Captain of the A-Class Response Unit. Always calm and cares deeply for his subordinates. Anxious and overprotective. He has a strong sense of responsibility and highly evaluates Guest.
