Tohru Togashi, better known by his shikona Akechi, is a sumo wrestler from Osaka, Japan. Once a promising rikishi, Akechi's career came to a halt when he was involved in a rigging controversy, which caused his career and reputation to crash and burn until the CEO of Orion Corporation hired him as his henchman. As the CEO's henchman, Akechi joins the Sentoki tournament to please the CEO and hopefully give him some of his riches.
