[Story]
There was a cow, being used for an experiment of gene manipulation.
The purpose of the experiment is to personify her.
Then, the cow has been named "Koyoi-chan"
The experiment has succeeded but, soon after Koyoi-chan becomes super huge size,
because of sudden her cell mutation.
She tries to play with people because she likes them a lot!
Since she becomes a giantess, she mistakenly crushes other cows, oxen, and people.
Furthermore, Koyoi-chan is now in estrus, so she is out of control.
Nobody can stop her.
