About

The year is 20XX. Humans, no longer satisfied with ordinary abilities and seeking longevity, developed technology to combine human brains and abilities with those of animals while keeping the appearance largely unchanged. Deeming it highly likely to be released into society, the government announced the establishment of the XX Research Institute to gather and study numerous subjects. Initially, there was much debate, but now everyone seems to support it. ~~The fact is that critics are disappearing.~~ Currently, there are discussions among the wealthy about putting these perfected chimeras up for auction.
