“You never know how many avatars are working hard behind the person chatting with you in front of you!”

- Description from novelbuddy

A 30-year-old NEET is reincarnated into the body of an otaku that choked to death on instant noodles. As he comes to grips with his new life, he realizes that this world is subtly different from Earth. The denizens of this world are far better looking, and this new world also possesses futuristic technology as well as mysterious Yin Yang masters!

The end of all worlds approaches.

The Demon King Order harvests lives from all manners of living beings.

Within this darkness full of despair,
A single person escaped from space-time, returned to before the world collapsed, determined to change the fate of the past.

But as time pass, he gradually finds out that the Apocalypse isn’t quite as simple as he thinks…

For He Yi, life was like a coffee table laid with all sorts of coffee mugs resembling her misfortunes. She lost her virtue and had a premarital pregnancy—without knowing the father’s identity—right before her engagement. Her father passed away due to a heart attack when his company wound up. At that point, He Yi’s child was one-month-old and the culprit behind these tragedies was her trusted husband.

Under despair and rage, she drove toward her nemesis to knock him down. That had resulted in her becoming a destitute divorcee who could not afford proper meals after she had finished serving her sentence in prison five years later. She lost everything and her child was snatched away by her nemesis.

Her ex-husband eventually married his mistress who was contemptuous of her. “How are you able to live with this? I’d die much earlier if I were you.”

He Yi only gave a slight cold smile. “The reason I’m still alive is to witness how you go to Hell!”
