User blog comment:DazzlingEmerald/Not Another One! Fanon Canon: Plot "Z" (Soul Society Civil War)/@comment-18812574-20150412044823/@comment-28861328-20150412170257

Yes, Brave, he would. His wife is a Quincy and his son is half-Quincy. His problem is with these militaristic Quincy that seem to only want the destruction of reality or to rule the dimensions. Three times the Wandenreich has emerged (if we count the Fanon Canon reemergence) and three times Soul Society has failed to properly kill them.

Mayuri admitted that Yamamoto is the only reason the current canon crisis even happened: because he failed to kill Yhwach. Obviously, the Quincy/Wandenreich weren't defeated in the canon since the Fanon Canon brings them back, so that marks failure number two. And now you all are discussing a civil war, which means Soul Society would rather fight each other than rally together against a single threat: the third resurgence of the Wandenreich.

In-character, this is going to make Raian livid and he is going to gather those who will want to actually do something about the Quincy, leave Soul Society, and deal with them himself, by any means. That's his goal.
