Flandre know that the third option is often the best.

Who DOESN'T want Koa over Remi or Patchy?

I wholeheartedly agree with Flan. Koa is the best out of the three.

Koa is the one that reads the Mukyu series to her after all.

it's simple math:
Koa > Charisma + Knowledge

I'd still pick the Patchster
Hate to break this to you flan but the Patchouli option has Koa included.

Good Choice Flan!!! Good Choice!!!

Well, all Remi had to do was hold out an arm for Flan to nom on. She coulda won easily if she didn't worry about the pain... xD

As much as I can understand Koa-love, you can't seriously put a character who's canonically mostly uncharacterized, with what little character she has completely the opposite of this above Patchouli. She's an oddball snarky hikikkomori min/maxed squishy wizard. What's not to love?

(And where are the Remilia fans, for that matter?!)
