I don’t know much about reviewing profesionally but I’m going to express my opinions here.
The storyline was great, it was original. I mean, I know all stories are unique in their own sense but this idea was greatly developed and put into something that made sense and actually touched my heart. I go about watching anime and enjoying it but in reality, there’s only a few that touch my heart to the core and Kobato is one of them. Certainly, it migh not be the best but it definitely is one of the best.
I surprised myself by giving the art a 10. It was different, in a sense and I noticed that most of the main women had long hair 😛 I know that the art of some things like K-On is a new style but the chibi moments and Ioryogi-san were really well-drawn. The art style is quite different from normal and caught my attention immediately.
The characters were well-developed and pretty simple, not so complicated. Kobato is your usual naive, innocent and pure girl with a big heart. She can stand up for herself and others, which I really admire in her. Kazehaya-kun is also another cliché character who is cold and aloof to Kobato in the beginning but gradually warms up to her. Sayaka-sensei is awesome in the sense that she totally understands the main characters’ feelings for each other and her love for her ex-husband. Ioryogi-san is one of the best characters that spice up and liven this story. His temper and genuine ( hidden ) care for Kobato is really sweet. The rest of the characters contribute in their own way and are one of the reasons I enjoyed this manga.
