KILLA is a Toei Games title with a venue-only trial version at Tokyo Game Show 2026 and a separate YOASOBI song of the same name, built from Maya Byo's debut novel I Want to Kill My Senpai, So I Cross-Dress, set for release within the year.
Two unrelated items share the name KILLA. Toei Games lists KILLA among the trial versions at its first Tokyo Game Show booth, held at Makuhari Messe from September 17 to 21, 2026. The booth also carries trial versions of HINO and DEBUG NEPHEMEE. DEBUG NEPHEMEE reaches Steam on September 10 and HINO on September 17, while KILLA is available only at the venue. Toei Games also schedules a crane game with TGS-exclusive mugs and a forum lecture with Sanrio and PARCO.
Separately, YOASOBI built a song called KILLA from Maya Byo's debut novel I Want to Kill My Senpai, So I Cross-Dress. Suirinsha published the book on Friday, October 16, 2026, through Hajimete no Literary Club, a project run with YOASOBI. The song is scheduled for release within the year. Ayase and ikura both gave comments on the creation.
The stories establish no link between the Toei Games title and the YOASOBI song beyond the shared name. One is a game demo tied to a convention booth; the other is a song tied to a published novel. Coverage does not say whether the two are connected, and it gives no release date or platform for the game beyond its TGS availability.
