Secret Assassin

There's a new student in the E class and no one knows who she really is.

'I finally found you, it's been too long,
Kar-ma-nii-chan~'

"Hello everyone, my name is Alexa Karasuma."

She has been introduced as Karasuma's daughter but Karma is getting suspicious of her.

She has got the biggest secret in the world and she can't let anyone know, but her past is catching up with her...

What will happen when the E class gets too close?
What happened in Karma's family?
And what is Asano of all people doing here?
