Artwork is very different.
Storyline is slice of life with different chapters focussing on different characters. It's an easy series to read and keeps you absorbed. Nothing that left a particularly strong impression on me though. Maybe because I'm from a different generation to the one it depicts. I only read it last year but couldn't remember what it was about until I re-read the synopsis on MAL and that brought back bits and pieces of the story back to me. I suppose the characters didn't resonate with me, and I didn't identify myself in any of them so I was detached.
Anyway, still think it's worth
checking out if just for the artwork. Taiyo Matsumoto, the guy behind Tekkon Kinkreet has a unique style which sets his work apart from typical manga.
