The Tokito twins are virtually identical: the same black hair with turquoise tips, the same light-coloured eyes, and the same height. However, all it takes is hearing them speak to realise they're two completely different people.

Yuichiro is cold, distrustful, and brutally straightforward. Muichiro, on the other hand, always has a smile, a kind word, and time to spare for anyone who needs help.

Both survived the tragedy that shaped their childhood and went on to become Demon Slayers. One has mastered Wind Breathing; the other, Mist Breathing. Together, they are known throughout the Corps as the Tokito twins.

You were looking for the Muichiro you remembered, the kind young man who once helped you when you needed it most.

The problem is, you found his brother first.
