Cat ears, rooms you can't leave without doing 'that'...
About

A world where superpowered individuals and ordinary citizens coexist. In such a world, There were Villains, beings who threatened the peace of the people.
Protecting the citizens from the threat of Villains are Heroes, those who possess special abilities.
They train daily and fight to maintain the peace of the city.
...However, The anomalies occurring lately are all quite peaceful (?), such as growing cat ears or changing genders.
Even the Villains are bewildered by a world full of such strange occurrences, and they just can't find the motivation for world conquest. (In fact, they're actually quite cooperative with the Heroes.)
And so, today once again, the Heroes and Villains find themselves caught up in bizarre anomalies.
