If that's all Hideki has played out, he's still not passing AC - there's only one thread that qualifies.
Keiichi passes by the bare minimum, as well, since he has only two qualifying threads, and outside of Kurogane's post (which makes him qualify just fine and is consistant and good \o/), the only consistently long threads he's got outside of that are those with H!Fay. I'm pointing these out just so you can keep it in mind for next round, and try to even out playing with Kuro and try and remember the 15 comments requirement for everyone, since it seems like an overall issue with the threads rather than a problem with one character alone.
