The human infertility was successfully prevented, but due to various unknown coincidences, many strange and peculiar points unexpectedly occurred...
Just when the Master was overwhelmed and went on strike, Almighty Man stepped forward!
Too many unique points to handle? It doesn't matter.
The last master of mankind is exhausted? It doesn't matter.
The heroes of human history are at your service!
(Actually, this is just a story about a master who is too tired and the heroic spirit is stuck in the tank!)
