Alien Species Knight Brigade

An associate professor in life engineering travels to a medieval European fantasy world. Using modern biochemistry, he discovers that viruses, bacteria, and parasites extinct in human history are actually the source of extraordinary powers.

He rescues and integrates the group of people known to the mundane world as "Alien Species," establishing the formidable Alien Species Knight Brigade that sweeps across the land, igniting a revolutionary wave in the medieval era.

The story is set in an alternate world with a fantasy backdrop, focusing on a dominance-themed plot. The tone is slightly serious and involves some biochemical knowledge.

The early chapters may feel a bit dull, but they become increasingly exciting as the story progresses.
