I should finish Keith MacKenzie's profile quickly.
Aside from him I suppose I can use Kazuma but in a scene dominated with OCs I feel kind of guilty for using a canon character.
Again, depends on what you define as "high tier" here.
In my book Kazuma is at best mid tier.
As for Keith MacKenzie his homonculi can be of practically any power so that's easier to balance.

EDIT: Also why there are so many posts in the IC while none of the characters were publicly submitted yet?
I thought we'd select the four fighters first.
So I'm really confused what's going on here.
