Well in accordance to the upcoming Volume 17:

Issei - See new special/finishing move first. Well it's not perverted the author mentioned it in Twitter. Well maybe it's something like the Compression Divider, a finishing attack for the CCQ.

Rias, Akeno and Koneko - further polish of technique

Asia - do nothing as usual.

Xenovia - Unknown for now, she seems to be doing a good job mastering the Ex-Durandal

Irina - Well i have no idea for her power-up.

Yuuto - Well start finding new possibilities. I'm still going with the 15th Longinus where he fuses the Demon Swords and SGs.

Ross - Wonder what her hidden talent is.

Gasper - Well i don't think he needs any right now. Just polish his powers.
