Key has announced a new anime crossover project based off their previous works titled Kaginado.

The series appears to be similar to Isekai Quarter which features chibi versions of popular isekai protagonists in a meta crossover series. In this case, the crossover’s foundation is their origin as visual novels from developer Key.

Key is known for their works such as Clannad, Air, Little Busters, and Kanon.
