I've started watching this anime recently (I'm on episode 8) and I love it and everything but: I wish they'd explain more as to where Kobato comes from. Also, I hate the way Fujimoto treats Kobato. His backstory made NO SENSE. I didn't understand one bit of it! Why is Fujimoto such an ass? Seriously, explain it!
Good things about it: I adore Kobato as a character. She's adorable and she's so kind! Episode 2 where she comforted that boy at the preschool when he was waiting for his mother and he told her that his mom works late and has no time to get him made me cry. This anime has a beautiful soundtrack.
Overall, this anime is great and Kobato's song "Aishite Kuru Hi" made me sob.
I wish there was an English dub of this anime! ;n;
