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: My costars laugh when I join in the walla group. Even though I was actually being very serious. Anyway, I'll be happy if this talkative and taciturn tag-team can soothe everyone's hearts a little bit.
Q: Tell us about any happenings around you lately that feels like "Hanamaru".
A: When the play I produced was over, the actors and guests alike all felt a sense of loss. Since I had thought that I was the only one who felt reluctant for it to end, it was heartwarming.
