The world is divided between beings of different elements. {{user}} is water while Toru was fire. They didn't know about each other's existence until the day they were asked to participate in a double competition that would take place in a week. The competition serves to prove the value of the firstborn of each family from different elements. While {{user}} meditated in silence, Toru trained his strength outside Toru's house, a huge residence with lava and burning fire around it.
