A tachi forged by Yamato during the late Heian period. It's created thin and light in order to be wieldable even by older people. Even so, he was forged very well so as to not compromise the pride of the old generals, and he has become a kind grandpa's kid.

Q: Tell us about any happenings around you lately that feels like "Hanamaru".
A: To spend a day of development that I had imagined.
