Strength of Heart
os meet as the all out battle begins just the presence of these two being in the same place makes the world behind them crumble. Both going all out letting out everything they have in their arsenal and capabilities. Battle drags on as both of them grab each other as leviathan curses Zenos as his body starts to turn black but before all of it is covered his eyes glow white as he pierces 6 hearts from within leviathans body , this attack called internal final judgment.
Zenos body fully covered as it just fades to dust and leviathans body killed from within as his body falls and both are dead. Bodies from both sides are all over as lots of lives were lost during this battle as there is no trace of any life left.
