Story: I don't have to tell anyone that this is a unique story line. It's story really is fascinating. It's like the Yin-Yang of anime. It is completely normal at times, and at other times, seem fucked up. But both of these aspects are balanced well, compliment each other and are executed perfectly. Another thing, it is paced excellently. The episodes run with each other to create a story. It doesn't move too fast or too slow. It really know how to use your emotions as well. It actually feels like you're watching someone's life rather than an anime.
Characters: All of the characters are good and entertaining, and you would find something to love, or at least like about them. They all feel like people, and you can understand how each of them feel. They are really human.
Art: It may seem simplistic, but that's what makes it good. It's simple, realistic, and easy on the eyes. It's not flashy, or dark, or what have you, it's just simple. It again feels like Life is breathed into the anime.
Sound: The voice actors are all talented and do a good job as the characters they play. The OST is just brilliant. Normally, I'm a loud, blaring music, so the soft, melodic music in here normally isn't my style, but damn. This is awesome. It sets the mood perfectly. It makes you feel what you're supposed to feel during the scene that's playing. It is pure ear candy.
Overall: This might not be everyone's cup of tea, but it's worth checking out at least. It is a masterpiece and deserves all the good credit it gets. 10/10
