I started playing Ryoubi. She has twin cat tails (like Kaenbyou Rin) but I couldn't take a good picture of them. I wish there were more customization options. I'm going to have to complete this game again on my JP account so I can mix all the items with DLC ..
I went for the Arle Nadja look and failed at it badly. What was i thinking last night? However she looks so cute in the battle armor anyway. She's my favorite of the new cast so far, her attacks match her over the top goofball and childish personality, she reminds me of a teenage Hina Takanashi from Papakiki with her younger personality intact.
There are no color sliders, only a single alternate color for most items, excluding school uniforms which may have 2-5. Some accessories have no alternates. Yomi's items in that picture are only available in a single color (white) except for Ryouna's costume, you can also get a black version.
