Dr. Ichigaki

Dr. イチガキ

Dr. Ichigaki is a demon scientist who exploited three martial arts students by poisoning their master. He then appeared and offered to heal their master on the condition that they agreed to participate in his experiment. Dr. Ichigaki transformed them into Makai minions (usually referred to as M1, M2, M3, or Dr. Ichigaki's minions). Following his team's defeat in the tournament, he reveals a serum ("Instant Gene Therapy") that almost instantly enhances him into a monster form, but he is defeated by Yusuke just as quickly. In the manga, he is confirmed to be alive.
