I'm Die, Thank You Forever is a weapon in HoloCure: Save the Fans!. It can be obtained through a collab between X-Potato and Holo Bomb. The weapon throws out bombs that attach to targets on contact. When a bomb carrier dies, the bomb explodes, shaking the screen and dealing massive repeated damage to all enemies in a wide radius.
The weapon is a reference to a stream between Mori Calliope and Inugami Korone where they were playing Keep Talking and Nobody Explodes, a collaborative bomb defusing game. Both talents challenged themselves by speaking in their non-native language — English for Korone, Japanese for Calliope. In one such attempt, as Korone realizes she has no time to win, she says the one-liner, "I'm die, thank you forever," in her final moments.[1]
