Written by Yuya Takahashi
Directed by Koichi Sakamoto
He brings a Bugster-infected patient and offers to steal back Emu’s Gashat in exchange of helping Kujo out with his prodigious gaming abilities.
Kiriya appears before Taiga and transforms into Kamen Rider Lazer. He challenges Taiga to a racing match with Mighty Action X as the prize. Lazer separates the Bugster from the patient,
snatches the Gashat from Taiga, and returns it to Emu.
Lazer goes into Level 2, which is a bike! Emu then gets on and both chase after the Bugster.
