Tanjiro headcanon for Demon Slayer

Headcanon

Tanjiro's kindness works best when it has ordinary roots. These headcanons give him small future plans that survive even when his life becomes brutal.

Before becoming a swordsman, Tanjiro wanted to run a charcoal shop and teach the village kids to read. He still practices writing during breaks. When someone asks why, he says, "Someday I will go back and make it happen."

Why it fits

The dream is small enough to feel believable for his old life.
Writing practice gives him a quiet action between fights.

A gentle scene can have another character mock the habit lightly, then realize Tanjiro is practicing for a future he still believes in.
