Info from the new short story. (I still don't know how the story panned out.)

I believe this is the title 英才教育お泊り会

Issei:
 * His favorite food is cheesecake.
 * Because of Kiba's words, the female students now view Issei with less prejudice.

Tosca:
 * She's scared of Irina.
 * She misunderstands Issei's and Kiba's relationship because of Kiryuu. The whole BL thing.
 * After she heard Kiba's act of revenge for them, she wanted to talk to Rias as she was afraid. But because of wanting to know more about Kiba, she was able to talk to her. Tosca thanked Rias with a voice thick with emotion for helping Kiba.
