Who did the voice for the blonde-haired Penguin King/Prince at the end? The voice sounded feminine to me.
Spoiler for penguin boy:
The same VA who did the voice for Himari's "fated one", Aranami Kazusa. And it sounds like a chick because Aranami is a girl. In fact, this is the first male role she does, so I suppose they were purposely looking for a feminine-kinda voice for Mario.
Btw, Masako called him Mario, so that settles that.
To tell you the truth, I think Mario is Masako's brother. I just didn't want to say it because:
2) a lot of people are surprisingly uncomfortable with the idea of Mario being a new character instead of one of the already established ones.
Spoiler for Spoiler for Steins;Gate:
I wouldn't care except for Steins;Gate, lol. Steins;Gate has won me over to the concept that important roles within the narrative should be filled by important already-there characters, and not brand new ones.
Just thought I should explain why my preference is what it is here.
