Mistake

"That's kinda annoying isn't?"

"Some paranoid humans biased the selection in the fear of the current Reaper being evil, in the fact that the race he came from is know to help humans in their needs and does good deeds! those people deserved to be killed!"

"Chill... it's just a story there's nothing to get angry about..."

"Or is it?"

"Enough of your delusion! just continue the story!"

"Kay kay here we go..."

The moment the "Reaper" appeared on the surface, the 7 Heavenly Heroes Simultaneously attacked the Reaper causing him in a near-death situation. his left arm is no longer part of his body, his bones are broken but his weapon and The 7 Heroes remain untouched.

The 7 Heavenly Heroes are two OP to be killed and he's so outmatched.

He doesn't have enough time to heal himself nor time to attack, so he retreated to his "Point-Zero" dimension only he can enter.

But one of the heroes said...

"if you continue to hide there... all the people you've cared about will be killed in the most inhumane way as possible you filfthy demon!"

Then the reaper unexpectedly did something impossible and would risk his life in it...

He activated one of his Curse in which it consumes his powers, his ability to regenerate and his ability to be a superhuman just to kill the Seven Heroes.

The recoil of the curse take effect and he is in a critical condition with no one nearby for help, he retrieves his decapitated left arm and fuse it in his body with the remaining powers he had...

Then the 7 Heavenly Weapons shine brightly in his eyes including the now Dead 7 Heavenly Heroes and an unseen entity spoke with the Reaper...

Your curse is not forever...

Their grudge, pain, and disgust into you is unerving...

They will return...

Along with their memories in this day...

Be ready...
