She just says things that are horribly stupid.. You'd probably notice in just a few moments of talking with her. Not to mention she has been getitng low grades ever since she was a little kid, and she's always so gullible too, just going along with whatever anyone tells her. It's almost a little sad, hm..?

Of course.. I don't want Nena-chan to go into a battle unprepared. [ Actually, it's mostly just so she has an even bigger chance of defeating whatever comes at them, but okay.. ]
