A tantou made by Awataguchi Yoshimitsu. One of the Toushirou brothers. The origin of his name comes from the stone medicine mortar that he cut, earning the reputation as a sword with "an extraordinary cutting ability but will not kill its master." Because he's raised for the battlefield, he has some medical science knowledge.

Q: Tell us your impression of the character you are acting as and what enthuses you most when you are acting him.
A: Attentive to his surroundings, he's a dependable older brother. It would be great if you can enjoy the Touken Danshi's daily life and struggles in the anime. Through the anime... will it be conveyed!? (lol)
Q: Tell us about any happenings around you lately that feels like "Hanamaru".
A: In a sudden thought, I went on a day trip to Kyoto! Without making much plans, doing this "unexpected stopover" was fun! Taking the train in that region was actually what I liked the most.
