In the year 20XX, humanity was destroyed—

All because of a highly contagious toxic substance.

Thanks to my purification skills, I became the last survivor.

[Hunter “Kang Yuha” has died.]

But when I opened my eyes again, I had returned five years into the past—

To the day, S-Rank Hunter Min Hajun, the number one ranker, died.

If I want to prevent humanity’s downfall, I must save him.

Even after receiving treatment from the guild, Min Hajun’s body had never fully recovered. Yet now, he felt lighter than ever.

“How did you do that?”

“…It’s my skill.”

Min Hajun was curious. The woman acted as if she knew exactly the condition he was in.

“This is bad…”

Because the world he had just glimpsed was far more pleasant than he had ever imagined.
