Having arrived in this rain-drenched world and being part of the resurrection event at Black Rain Villa, one must be prepared. Whether it's the resolve to kill or be killed. Logically speaking, those who kill must also be prepared to be killed. In this world, death is the only absolute fairness!
Thus, the four forces within Black Rain Villa were all treated as punching bags by Casio. When he came before a faction, he would release their pressure constraints. He gave these weaklings one last chance to roar and clench their fists, fighting for a sliver of vitality. If they wanted to surround him for an attack, then so be it, enjoy the pleasure of the final battle. Dying in such a battle is undoubtedly the happiest thing.
