Otherworldly Munchkin trailer out along with vibrant key visual – anime premieres in October

An Otherworldly Munchkin trailer and key visual have been released today, along with the fantasy action adventure anime’s premiere date — October, 2025.

The main cast and the anime’s staff were also announced via the Otherworldly Munchkin‘s X account.

The anime’s latest key visual is visually striking as it features protagonist Yukito Kirihara with his World Book, alongside (left to right) Charlotte R. Brownia, Lumilia Sherwood and Liverna Dark (back) — all of whom appear as though they are ready to launch an attack.

The accompanying trailer gives us a quick look at Yukito Kirihara as he arrives in the Everworld, becomes a Level 1 wizard but then realizes quickly he only has 1 HP.

That means any attack at all, even one a baby could deal with, would kill him instantly.

But a bevy of beautiful women seem to be soon making sure that will never happen. (Watch below)
