He is a person of culture, however he supports a solid physique and has the bad habit of solving things through brute force.
Comments from Voice Actor
Q: Tell us your impression of the character you are acting as and what enthuses you most when you are acting him.
A: He's a very graceful and elegant character, so I want to reveal that side of him! I also hope I can portray the gap between him when taking care of the houseworks and when fighting, even though I'm not sure if there's one.
Q: Tell us about any happenings around you lately that feels like "Hanamaru".
A: That time when I managed to think of a super effective housework schedule and it fits me really well, it's Hanamaru. After that I got red mark for getting too happy about it that I can't sleep though.
