Somehow Shimoda stumbled into an underground kingdom.
This kingdom is a land for "animals that create the perfect society", with their queen at the top.
In this society, there are few physical differences, no aging, and the collective's happiness is prioritized over the individual's. It's too ideal a place, but there is a hidden truth about this system
I thought not aging would 
be a good thing.
ظننتُ أن عدم التقدّم في العمر شيءٌ جيّد
Ich hielt es für gut, nicht zu altern.
Pensaba que no envejecer era algo bueno,
Pensaba que no envejecer era algo bueno,
Je croyais que ne pas vieillir
était une bonne chose,
Pensavo che non invecchiare fosse una cosa bella...
Achei que não envelhecer
seria algo bom...
Я думал, что не стареть — это хорошо...
