The Most Ambitious Crossover Ever

Kazuma and his merry gang of idiots is back in a new show this spring called Isekai Quartet. In Isekai Quartet, the Konosuba gang is joined by 3 other popular isekai shows. These shows are Re:zero, Overlord, and The Saga of Tanya the Evil.

I present to you the opening of Isekai Quartet in all of its glory.

If we ever get a season 2 of Isekai Quartet, I hope that they will add Rimuru Tempest to the isekai roster.
