加藤 一樹

Hitomi's partner in the DATEN tournament. In return for helping Hitomi win the tournament with his advice and training, she's willing to give him the three million yen prize money because her main objective is to find her missing older sister.

A big fan of the famous wrestler Falcon Yamagata, he initially aimed to emulate his idol as a professional wrestler but discovered he wasn't talented enough to succeed in wrestling. His switch to being a personal trainer was in the hopes of supporting wrestlers like Falcon Yamagata.

He is very knowledgeable of the wrestling word and its personalities and is capable of recognising the masked wrestlers in the DATEN tournament based on their physical attributes and techniques alone.
