Really? xD, man, a Valk player is something so weird to find online that I have almost no experience against him, so he's one of the characters I wanna fight the most.
That's the main problem, that through match experience, you have to deal with al lot of things, so if you focus in an specific aspect, you leave alone the others.
In P4 Adachi became in what Minazuki wants everyone to become: A human becoming shadow, because being swallowed by their darkness, but after being defeated he returned to be normal.
