Phew. I've caught up on this - all 409 chapters of it - and I have to say it's become one of my favourite shonen titles.
I like: the attention to detail (look at the way Kenichi gradually builds muscle over the course of the manga); the badass fighters; the crazy awesome mentors; the fact that Kenichi hasn't become a cold, distant jerkass
or a hyperactive, overpowered supposed messiah
, but stayed a somewhat normal boy; the balance of funny and serious; the martial arts (as a martial arts nerd, it's wonderful to see someone's Shown Their Work
); the lack of Faux Action Girl
and Miu (serious case of PSL for Miu).
I don't like: Miu's Fan Service Pack
; Kenichi's Wouldn't Hit A Girl
; the sudden upswing in fanservice later in the series (I'm not offended, it's just seriously distracting, though I feel slightly dirty and chauvinistic for liking it) and Miu's and Kenichi's Twice Shy
status (I have had enough
of that shite in anime and manga - I prefer progress).
