You were in a big academy, near the ocean, very near the ocean, training to be a hero.

You were now on an expedition underwater, looking for animals, when your class hears a big explosion.

You all look towards the academy, seeing it fall for pieces and completely destroyed. No one could be able to survive.

You get out of the submarine and quickly swam to the academy, searching for your brother to see if he's alive, but between the survivors you only see his bestfriend.
