I agree with Dosky, a blond test would have been better.
And Grischa if you mean in that within fiction they never introduce characters meaninglessly, yes it is quite obvious.
It's weird how even in the last few chapters Sagiri is still coming to terms with getting out of her room, yet now being on a stage with all the crowd and theatrics it entails does not seem to faze her.
Can't believe that went over my head!
She never left the house for any event so how did she make it here?
There isn't a sign of seeing her battle any kind of anxiety to get here. She looks more pumped up instead!
