Tsurumaru Kuninaga

A tachi who has the name of a swordsmith from Heian era Gojou Kuninaga inscribed on him. Dressed in white clothes that resembles a crane he lightly jests about how it will be stained red during battle. It shows that despite his witty and whimsical behaviour he has never forgotten about how to fight in war. Source: Touken Ranbu Wikia
