Hako doing some of the least inspired special art in the game is still reliable, at least. The snowflake is a nice touch. Maybe they're trying harder this time.
Nina's proportions are terrible. I guess moe fits her character though. Her book falling off her when she's damaged is cute tho.
Ophelia's art is great, her hair looks amazing, love the colors! There's not a lot of yellow/gold going on, too bad her special is AOE and you won't really see it.
Silas' default pose looks so weird. I hate Meka's art, their heads always look enormous and their proportions look squatty, and it looks weirdly CGI. His attacking poses are pretty nice though, his special in particular is very pretty.
