PERFECT CASTER

GRUMPY TINY ANDERSEN

I laughed way too hard at this. Of course I'd summon Andersen. xD

We'd probably lose the war, but at least I'd be able to bug him about The Little Mermaid! And about how much of a little shit he was to other people.

Oh, I wouldn't be so sure, he wasn't bad in Extra CCC

I know what he looks like already, though I haven't played Fate/Extra. ^^;

oops lol

From what I read, he seems to basically be a grumpy, blue brat.
