Mori Calliope isn’t just a megapopular VTuber with 2 million subscribers and a discography that goes hard—she’s also a diehard Gachiakuta manga fan who’s lowkey been fiending for this kind of opportunity. She’s a part of the crowd who liked it before its anime adaptation made it mainstream. Her upcoming Gachiakuta theme song, “Let’s Just Crash,” aims to be a sonic embodiment of Gachiakuta’s volatile rage and righteous fury, mirroring Rudo’s descent into The Pit and his fight to reclaim justice.

In our chat, Mori Calliope broke down how “Let’s Just Crash” channels Rudo’s ongoing journey as the anime’s hero, how VTubbing let her cross the line from fan to creator, and how she hopes this collab will be the first of many to come as anime and VTubbing jointly become core tenets of pop culture.
