Adventure in an unkown story - Touken Ranbu

The Saniwa is not here, the swords are in dissaray.
In the middle of this all a stranger barges in their lives and tries to help the residents of the poor Citadel, be it willingly or unwillingly.

Who cares?! I just want an excuse to see my beloved character in a I place I know of.

(An excuse to write an OC exploring Touken Ranbu, no regrets (for now) )
