黒森枠は（現1年生キャラ不在だったので）オリキャラ

【追記】僕の知識不足でしたが黒校も1年生が登場してる可能性あるみたいです、コメントで教えて頂きました

As for Kuromorimine, it's an original character (because the freshman characters for them are absent).

[Edited] I didn't have enough knowledge, but it seems that there's a possibility that the freshman did appear also at the Kuro school, as was mentioned in the comments.

[tn]The Kuromorimine freshman mentioned above is Sheska.
