I don't know, but I can't imagine Karasuma getting kicked out of the storyline for good just like that. Especially not in a manga like this, it's not the type that deletes characters. Can't tell how he's going to stay though.
You make your face a mask. A mask to hide your face. A face to hide the pain. A pain that eats your heart. A heart nobody knows.
Well, it's official.
Karasuma is a badass.
^yeah, and he's a better match with Harima than Hanai..
