Touken Ranbu: Testing the Limits of Making Kuro Uguisumaru Black

Excerpt from Uguisumaru's diary

XX year, X month, X day. The weather is sunny.

The cherry tree in this citadel blossomed today. As usual, I had tea with Mikazuki. It was a lovely day.

I would have been even happier if the General hadn't mistaken me for Hizamaru. Hotarumaru isn't any better.

We're all Marus, so why doesn't my name deserve to be mentioned?

I'll remember this grudge for now.
