Masaaki Mochizuki
Since the dissolution of PosHearts, Shisa has remained unaligned and wrestling low on the card. He is a trainer in the Dragon Gate dojo, and focuses primarily on those duties. While wrestling on the main roster, Shisa aligns with the "Mushozoku" Unit, a group of older wrestlers including Masaaki Mochizuki, K-ness and Magnitude Kishiwada. Aside from Dragon Gate, Shisa spends time in various smaller Japanese independent promotions.
