Created by Aster Phoenix's father, Aster uses a Destiny Hero deck, consisting of Dark Warrior-Type monsters that resembles the "Elemental HERO" archetype that Jaden uses. Its playstyle revolves around using Clock Tower Prison by stalling the duel, and then destroying the field spell to special summon Destiny HERO - Dreadmaster, along with the other destiny hero monsters for a beatdown.
Asta wanted to find who ki lled his fatha, so he got inside a weird cult in order to "learn about his fatha" and eventually find the criminal.
But this extraterrestrial dude tricked him and deceived him. Then the ET became a father figure for him.
To make it even worse and complex, Sartorius, this extraterrestrial is also being manipulated by some entity who makes people believe in something hierarchical and fallacious. Hierarchy = False god.
