椎葉琴香

Kotoka Shiiba (born January 8, 1990), better known mononymously as Kotoka, is a Japanese semi-retired professional wrestler. He is best known for his tenure in Japanese promotion Dragon Gate from 2009 to his initial retirement in 2018, where he became a one-time Open The Brave Gate Champion. He has since made sporadic in-ring appearances as Gym Trainer Kotoka, as he began to "run so many gyms" since his retirement.
