Has the Test Subject Been Tamed Today?

Every experimental subject is created for just one purpose: to contribute to the research institute.

But the subjects are uncontrollable and do whatever they please.

The first batch of experimental subjects was a failure: powerful, but uncontrollable.

The second batch was a failure, too. Their powerful bodies couldn't make up for their fragile hearts.

What if the first and second batches met?

What would happen?

A miracle, or destruction?
