Komidol from MeltyBread has been in Japan for a while, and attended the 2011 HydraGP event for Melty Blood Actress Again Current Code! This was a semi invitational tournament for MBAACC Ver 1.05 , capped at 64 players held at the Tokyo Metropolitan Industry Trade Center. The Ecole CEO was in attendance, and it was also the first event with MBAACC Ver 1.07 available to play.
You can read Komidol’s lengthy write up of the event and the followup party at his blog here. Japanese speakers can also go to the official writeup on the HydraGP homepage. Interestingly enough, this tournament wasn’t a traditional one: there were 3 pools, with the winners of each pool qualifying for the top 8. The other 5 were selected by Ecole CEO Manabe, based on who he thought played the best. The 3 players who won their pools were Maruyama(Ciel), Hagi(Powerd Ciel), and Jin(Hisui). Hare, who won the last HydraGP tournament, automatically qualified for top8. The other 4 selected were Ashe(Powerd Ciel), Kanna(Miyako), Hecht(Miyako), and… Korean CL! Probably on account of him being the only person from that country in attendance. Hare would eventually win the tournament, with Ashe getting 2nd.
The other interesting bit of information is that the PC release of MBAACC 1.07 will have a CD key system. It seems like Ecole was very aware of how much MBAC was pirated, so this is a good way to make people buy the game.
