Demon Sword Maiden - Volume 3, Chapter 108 – Flames of Mt. Fuji

She is a two-faced and fierce hidden ghost doctor,

An underprivileged prodigy, a cruel, ruthless world, and an epic story of battle and conquest. A young man with an exceptional inheritance leaves the small, rural city from which he hails on a journey to find the girl of his dreams. He defeats countless prodigies, sweeps through all forces that dare to stand in his way, and progresses step by step toward the pinnacle of all the worlds!

Ukei Kaito fought a desperate struggle in order to fulfill his role as a summoned hero. He defeated the Demon Lord and saved the very world, only to meet an end filled but with betrayal.

The Soul Federation Scientific Exploration team found an egg with a golden and silver pattern on it in the far north of the land, and after examining it with an apparatus, they found out that there were vital signs inside. They hurriedly brought it back to the institute for hatching.

The egg hatched, but it was a baby, a baby exactly the same as a human – a baby born out of an egg.
