If its the 4 main girls then its Riko>Shirayuki>>Reki>>>>Aria
Reki is too much selfless for my taste. She only thinks of Kinji and think of herself as a tool. Sad and pure girl. Riko will "play" with you and Shirayuki is "victory" and lets not talk about Aria. I'm fine with my body as it is. I don't want it to be full of holes.
