game2534> Trust me or not but Strawberry Candle is one of my main girl on Nutaku. Just because her Solar Node ability. With her my solar gauge is almost always full and I can kill every pests or bosses on event in one turn. For me Cosmos is really far behind in term of battle power. And I like playing with Solar Blast yes.
Just to be sure, I tested her instead of Japanese Iris. Cosmos does arround 7k damages on weak pests. Japanese Iris does 11k. Cosmos is just too weak for any kind of job. Strawberry Candle or Peach are better for Shine Crysal drop, every other defense girls are better for defense boost.
But hey, I still like her anyway like my first gold ever. Even if I don't like her evolved form. Bloomed one is so much better.

Hopefully, she seems better on DMM. Still not that good but she is decent.

twilightdream> Yeah, I'm peaking of that pink cat-ears hair style Cosmos with her japaneses clothes. Not Chocolate Cosmos with her colocolete statues, which is a good one.
