Sendai Girls' Pro Wrestling
Hamada was arrested on May 13, 2018, for possession of methamphetamine. Her arrest resulted in Pro Wrestling Wave terminating her contract and Sendai Girls' Pro Wrestling stripping her of the Sendai Girls World Championship. On July 18, 2018, she was given an 18-month prison sentence, suspended for three years. The same day, Hamada announced her retirement from pro wrestling, hoping to find work as an interpreter.
