There is a way to die even for the immortals?

There is.

T...Tell me more!

All right...then let's start from right after Judgment Day 4 billion years ago.

When my body was resurrected following the meteorite impact..

...it was raining acid all about.

Eirin was right here.

Good morning...

Long time no see...?

Welcome back. It has been 49 days.

After the impact, sulfur contained in rocks evaporated, became sulfur oxide gas, and poured down as sulfuric acid around the world. According to research in 2014, the dinosaurs went extinct because of such rain.
