#without exceptions

Ueda Keisuke: “You audience would have already known this, but our Yamaoki Yuuki is really such a weird guy. A total airhead. The ‘super teased character’ among us. It’s either Okki’s quirky remarks, or Ryuko’s adlib.”

HiroDai: “If it’s about when we’ve started teasing Okki, it’s right from the first performance. Or from the first time he showed his face. He has this face that’s really easy to tease. At first he’ll get angry at it here and there. But there was one time when he got annoyed and it's very cute! That part of him that doesn't understand what he's even saying is very cute. He said how his honesty is similar to Russia, but the actual person would be Germany instead XD

Okki: Ryuko told me during practice halfway that I suit Germany better than Russia, and the staffs were also there to hear it and they gave this impression that ‘It would have been better if Yamaoki was not casted.’ They didn’t actually say that but I feel that Ryuko-kun felt somewhat bad about it. 

Isogai Ryuko: I really thought he resembles Germany more. I casually told him that, about 3 days before the actual performance, “I think rather than Russia, you suit Germany more.” He gave such a worried face and said “Ah, I see. Yeah, I think so too.” But in actuality, it totally doesn’t suit him, it really doesn’t suit him. That child really has a weird way of thinking. The way he responds to things is so different that sometimes it’s misunderstood.
