When I first saw Kokoro in HM I thought for a second that she was strangely dressed Satori until my brain could process the fact that she was a new character
Satori: "Sorry Koishi, but you are adopted. I found my long lost sister"
We look pretty similar, right?Big sis, I'm home.Koishi...Pleased to meet you...This here is a friend of mine, Kokoro-chan.The truth is that I had another younger sister.See...P-...Just what are you saying, big sis?
Although the hue between you two is pretty similar...
