He still doesn't know how she feels huh? Like the scene in v17 with those two, or even v14 where she said she wants to get closer to him and he knew exactly what she meant? Mhm, density overload.

@Jop It might be a bit cheap to give the title away, but it's the logical way I see Ise working on his peerage and Rias achieving her goal before the series ends. If the Gremory group were strong enough to defeat the Champion and his team fairly, then, assuming they go the normal points requirement way, they could defeat pretty much everyone without much issue aside from restricted games.

...Or, Rias is awarded enough points for defeating Belial even if it was not in an RG. That could work too.
