A 28-year-old master of Muay Thai and is known as the "Death God" of the Muay Thai underworld fighting circuit.

Apachai has been fighting life or death battles in underground Muay Thai fights since he was a teenager. Later, he was an enforcer for a cruel pirate who accidentally fed Apachai while he was starving in a harbor in Thailand. He served this man faithfully until Hayato Fūrinji brought his misdeeds to Apachai's attention. The two of them then defeated the pirates, and Apachai has been at the dojo ever since.

From wimp to warrior. Sort of… 
 
Yeah, Kenichi’s a total wimp. He’s always getting picked on and doesn’t have a lot of friends to stick up for him. The guy needs motivation if he hopes to graduate in one piece. Well, Miu’s the perfect motivation. She’s hot, she accepts him, and she just so happens to live at a dojo with six martial arts masters. You could say fate has led Kenichi to their door, or you could say he was just following the hottie. Either way, he’s about to get whipped into serious shape. If he can survive some hard-core training, he might survive another day at school. He might even score with Miu. Yeah, you could call Kenichi a wimp. But let’s go with underdog instead.

After Kenichi witnesses Miu's skills in martial arts, he joins the Ryōzanpaku dojo, the gathering place of those who are truly strong, which also happens to be Miu's home. After beating a karate student in a match, he is soon targeted by all the delinquents in the school. Since then, Kenichi's routine is divided between his hellish training with the masters of Ryōzanpaku, and his fights against the members of Ragnarok, a gang who views him as either a possible ally or an impending threat to their plans.
