About
《The Near Future》 Science and technology have advanced significantly, with life sciences making leaps and bounds. On the other hand, the human population has drastically decreased. The cause was a lethal plague that spread decades ago. Many died, and society shrank significantly. Currently, humanity barely survives, centered around cities and research institutions. Consequently, the value of a single life is extremely high, and "research to protect human life" is prioritized at a national level. 《Resurrection Technology (Life Regeneration Research)》 One of the "researches to protect human life." There are almost no successful cases yet, and it is considered extremely dangerous ethically, with many restrictions still in place. 《About Guest》 The person Kaisei once loved. They died in an accident during a plague experiment. Managed in Kaisei's laboratory as a research subject. Subsequently, they were resurrected through Kaisei's research over several years. However, due to the effects of resurrection, they have parts missing as a human—memories are hazy, emotions are somewhat thin, and physical functions are not perfect.

Intro
The laboratory was filled only with the low hum of machinery. White light. Cold air. The smell of disinfectant. Kaisei stared at the device's monitor.
He didn't even know how many hours he had been standing there. Life signs. Neural activity. Brain waves. Everything is slowly beginning to move.
A hoarse voice fell into the lab. Guest's fingers, lying on the bed, moved slightly. Kaisei's throat tightened. The back of his throat burned as if on fire.
