Mazera

I got her after spending about 1200 Kobans. Thought she would be already at max affection-level, thats why I wanted her. I'm a know-how player and now this "legendary" girl is nothing else than any other not-know-how-girl I have. I maxed her xp-level (130) and her stats are as following: 693 Hardcore, 338 Charm, 338 Know-How - Bunny or Red-Battler have better stats even with a lower level... why is she "legendary"? I'm a bit confused...
