Grisaia no Kajitsu

[shinta|hikari]

I always found the bus incident so unrealistic that I can't really judge it one way or another. In the first place the fact she remained there and didn't leave to seek help (despite having the wits), kind of suggests she didn't want to bear the responsibility or make the final decision. On the other hand, I do consider her somewhat (childishly?) wicked so it's possible she simply enjoyed watching the other girls' mortal struggle, having perfect faith in her own ability to survive no matter what.

Everything she did during that incident was calculated. It was shown in the anime pretty clearly, so your interpretation is completely off base. She even explained her actions herself.

She was living in her parents' home like any kid. It doesn't take a genius to downplay one's abilities if all the attention starts to look like a huge bother.

There are laws in Japan preventing her from simply leaving. And that second sentence doesn't make sense. It is precisely because she is a genius that she has abilities worth downplaying. Even talented adults are desperate to show off their skills in the dog-eat-dog world.

What I'm basically saying is, this is anime and kids who aren't really kids are all over the place.
