Much like Kairi, who lost her Wonder of Stardom Championship to Mayu Iwatani yesterday (May 14) in Korakuen Hall, Io will have a bit of work to do before leaving. She retained the World of Stardom title against Toni Storm in a half-hour draw on the same show and Mayu challenged her immediately after, setting up an obvious title unification scenario, even if only temporarily.
However, since Shirai's start date with WWE is currently not set, Stardom would seem to have a bit of wiggle room to get the title on whoever they'd like.
If you're not familiar with Ms. Shirai, why not have a highlight reel?
There you have it, folks
Io Shirai will indeed be joining Kairi Hojo in WWE. Excited?
