A senior year student and deuteragonist/support character. Intimidating, cold, stern, antisocial, and having an unconditional love for his brother Reiko, he's willing to take the odds against him in order to protect and retrieve his family member. Serving as a guide for Yaso and reluctantly accepting Daro's sudden invitation within Kazuken's body, it was sad to see that Kazuken met his death by the hands of Quillie Beckson. Or so it would seem. Trace, a supportive character, took the courage to check and see if there's any survivors and, lo and behold, Kazuken is still breathing. Trace uses the leftover bandages from the roll and utilizing medicine to cure his fatal wounds and carrying (painfully) Kazuken to the meeting room with the others and waits until help arrives. Kazuken isn't among the surviving 6, but is rather among the special survivors because he endured a lot of hate and backlash from others on the topic of his brother, who are now reunited.
