With the latest chapter, I realized I was getting completely lost with who's who and reread the series from the beginning. Whee. Even knowing what's coming at the end of part 1, it still works. Assuming Adachi doesn't fumble it -- and given his skill, that's doubtful -- I think we're looking at another masterpiece on the order of Rough and H2. As in, yes, better than Touch.
Given Koh's still in his second year, it seems doubtful they'll win (if they even make it to) Koushien this round. Besides, Koh still wants it for Wakaba, not himself or Aoba -- and even once he changes, he'll have to convince Aoba of that. So we're looking at, at least, a dozen more volumes. If we reach exactly Touch's length, I'll be officially Amused.
If Koh ends up buying Aoba an engagement ring on his 20th birthday, I'm going to SMACK Adachi.
