The characters are easily the biggest part of the story. I enjoy them. I like the responsible one. I like the goofy one that is always shouting. I like the serious and one obsessed with the MC. I do like the MC too. It's a nice mix of characters. I being a man of Yuri/Shoujo AI. I can defiantly say this passes the Slice of Life Yuri genre meter. I also like the teachers and cousin set of characters. I do hope we see more in the future. It's a nice batch of characters with all the interesting personalities. Nothing groundbreaking but nothing awful.
