Io Shirai’s WWE Contract & Debut
In 2017, Io Shirai signed a contract with the WWE after she took part in a tryout at the WWE Performance Center in Florida.

Shirai made her in-ring debut at the second annual Mae Young Classic Tournament in 2018. Io Shirai made it to the finals but was defeated by Toni Storm at Evolution.

This led to a match at NXT TakeOver: 30 where she successfully retained her title against Dakota Kai despite interference from Kai’s enforcer, Raquel González.
In September, Shirai renewed her rivalry with Candice LeRae. As a result, their feud sparked two title matches at NXT TakeOver 31 and NXT: Halloween Havoc, including the first ever tables, ladders and scares match, in which Shirai retained her title. On the November 18th episode of NXT, Shirai also successfully retained her title against Rhea Ripley.
At NXT TakeOver: WarGames, Shirai was a part of Team Blackheart (herself, Shotzi Blackheart, Rhea Ripley and Ember Moon) who faced Team Lerae (Candice LeRae, Toni Storm, Dakota Kai and Raquel González) in a losing effort in which Shirai was pinned by González.

Shirai Wins Tag Team Gold with Zoey Stark
Io Shirai made her return on the June 8 episode of NXT. A few weeks later, she partnered with Zoey Stark as a tag team.

On the following episode of RAW, the trio targeted and attacked Becky Lynch, Alexa Bliss, and Asuka. SKY’s debut match was against Belair in a non-title match resulting in no-contest due to interference from Asuka, Bliss, Kai, and Bayley entering the ring and starting a fight.
Damage CTRL Wins Tag Team Titles
On the September 12th episode of Monday Night RAW, Dakota Kai and IYO SKY defeated Aliyah and Raquel Rodriguez to win the WWE Women’s Tag Team Championship. They called themselves Damage CTRL.
