Martial King's Retired Life - Chapter 67Book 15:

“Hey, Yoshi-kun. I think you’re——”

Hearing that voice for the first time stopped me in my tracks. On my way home from school. On the playing field of our junior high, and at the bookshop in front of the station. And then in the empty lot where the white cat slept. Shiina Yuki, the strange girl who somehow knew all about me, always approached me like that.

We laughed, cried, got angry, held hands. Again and again, we repeated those disappearing memories and ephemeral promises. That’s why I never knew. I never knew the value of Yuki’s smiles or the meaning of her tears. Nor even the singular sentiment behind her many ‘Nice to meet you’s.

This is a captivating, heartrending tale of meetings and partings.

The protagonist of the collapse of the three former civilizations is Dr. Mei. What is the end of logic, the strongest brain, super intelligence, this is the story of the strongest scientist of Honkai with knowledge of the moon becoming the god of science!
