|Epithet:||"The Evil Emperor"|
|Seeker Debut:||Chapter 10|
Hayakuwa's most distinguishing feature is his hair, which he wears in a single long, crescent-shaped bang that covers half of his face. He is well muscled and tall, towering over Oshio Gaku, though being dwarfed himself by Ando Rei. He can sometimes be seen with completely black eyes.
When announcing the no-holds-barred Rokushin Kaikan tournament to the top members of Rokushin Kaikan, Ao Kenji mentioned that he planned to incentivise Ikeuchi to participate with the presence of someone Ikeuchi had a grudge against. This fighter was revealed to be Hayakuwa when he suddenly met Ikeuchi and declared his entry into the Rokushin Kaikan tournament. This was ultimately what spurred Ikeuchi himself to enter.
After this, Hayakuwa entered the tournament, being placed in C block.
Powers and Abilities
Hayakuwa is a powerful and intimidating opponent. Ikeuchi Mentaro considers him the strongest Nak Muay he knows and also possibly the strongest man in general. Hayakuwa's elbow strikes in particular were strong enough to rip Oshio Gaku's face open and nearly cleave his hand in half.
