Go ahead and live with your head held high. No matter how devastated you may be by your own weakness or uselessness, set your heart ablaze. Grit your teeth and look straight ahead. Even if you stop and crouch down, time won't wait for you or snuggle you and grieve along with you.

The Demon Slayer: Mugen Train is not just a movie, it's more than that.
