On January 5, 2023 at *New Year Dash*, O-Khan stared down Shingo Takagi, holding his Undisputed British Heavyweight Championship, as way of asserting his superiority over him. In a backstage interview, O-Khan challenged Takagi to a match, which Takagi accepted; despite seeing the KOPW Championship as a way to challenge Kazuchika Okada for the IWGP World Heavyweight Championship.

Oka noticed the incident and after the girl asked for help, he managed to calm the girl, subdue the man and save the girl's mother from a critical situation in the station restroom. On April 4, 2022, Oka received a letter of appreciation from the Nakahara police for his efforts.
