The memories of a man in his forties, who has lived through the Showa, Heisei, and Reiwa eras, suddenly awaken within an abused young child.

This is a story about a science teacher struggling to save a toddler on the brink of death.

How will he survive in a situation where he understands nothing...?

The story is set during the childhood of a real-life Sengoku period warlord.

While he is a famous figure known to many, his true identity and background are not clearly documented.

The protagonist, having studied world history in high school, only possesses a junior high level understanding of this era and knows nothing about himself or the local situation.

In this work, such historical background is largely irrelevant; the main theme is the "hell mode" survival of a modern person who has stumbled into the Sengoku period.

Please read this as a fantasy.
