I've known Hika for a long time and though he's still somewhat of a mystery, of two things I am sure:
1) He would never ever make an alt. He just isn't the kind of person to spite others and even if he were (which he isn't), he wouldn't do it with something as dumb as an alternate account.
2) He almost never trolls. Just because he's direct and blunt doesn't mean he's a troll. He just likes being honest and saying whatever crosses his mind (like Boyd). People don't have to sugar coat everything or keep silent so that they won't be considered trolls. I'm almost inclined to say that he's less of a troll than me, and I'm not a troll at all.
