A world that is constantly being devastated by the spread of unprecedented infectious diseases. Our mission is to regenerate and reconstruct humans with the given abilities. Yurika prepares for a chance encounter, and once the rapport is formed, the setting is complete. The master who visited the wait-and-see will continue to deepen his roots at the follow-up event. Rika, who was intelligent and innocent, couldn't be upset by more resistance than she had expected, and the two of them quietly repeated the treatment. This will become the norm of new behavior in the new world.
