How do get a destiny in Grand Academy for Future Villains 2?

I have played through TGAFV2 a couple of times (holding out for a sequel) and have yet to get a destiny. For those who have played the game, any tips to get a destiny?

I got a destiny my first try. Whatever your MCs strength is, play to it. Support your dorm-mates, strike out for yourself, whatever it is. Do not suddenly change your tactics.

thanks

Really hasn’t helped but thanks anyway
