This manga is amazing! At the beginning, it's a little hard to understand, but we get the hang of it and from there, it's a very heartfelt storyline. I agree that the manga artist could have made Ruika look more like a boy when she's trying to be her brother, but it's very good anyway. The end was shocking and that's what made it unbelievable! I really recommend it if you like fantasy, drama and shoujo!
