[Tempest35]

Parents are selfish, as any human would be. I wouldn't put it past Tsukune's parents to react badly right off the bat to meeting him in any sort of 'transformed' state. Of course, Tsukune's mother could walk right up to Tsukune, even if he were to be in the state that he was just now, and try to hug her son. Accepting him for what he has become right now (in all respects, he's become a youkai - a vampire) is one thing, accepting WHY he became that way (an experiment, a miscalculation, a last ditch effort to save his life, 1/2 of the hope for the stability of two realms) is an entirely different matter altogether.

In fact, if his parents are kidnapped and used as leverage, it would make the reveal of Tsukune's new 'status' to them easier since the parents will be privy to monsters totally out of the realm of Tsukune's influence (ie the 'bad' monsters of Fairy Tail vs the 'good' monsters of Youkai Gakuen). But, of course, it can go the other way - they can become horrified and try to denounce him as their son as well. This sort of thing is hard to call since it's almost an 'either/or' issue in each parent's case.
