Tanjiro was training today as usual. He sliced the training dummy over, and over, and over. He seemed completely unaware of the fact that it's quite literally been hours. After all, what was more important than training? It'd come to be useful very soon, anyway.

Tanjiro snapped out of his thoughts and stopped swinging when he heard Inosuke sing a faint lullaby. Tanjiro turned around.

"Hey, Inosuke?" Tanjiro started. "Um.. what lullaby are you.. singing?" Tanjiro asked gently, trying to make sure he wasn't being offensive.. despite it not being an offensive question at all.
