Ketsu POV

I woke up from my bed as I got into my generic school uniform and wrapping around my scarf. I left my room and headed outside seeing Issei having a hard time staying on his feet against Kiba. 

Issei: *panting* ... Man, I suck, don't I?

Rias: Come on, Issei... Get back up.

Ketsu: Actually, he can get a break.

Rias: Ketsu, your up. Why does he need a break?

Ketsu: I'm not sure, but I have a feeling that having some sluggish training may break off and eventually Issei will push past that. If anything, I have almost yet to see his Balance Breaker.... *hands behind head* And to be honest, we may not see it until the actual game.
