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
Oh, I've heard of that! But we don't age.
Oh, davon habe ich schon gehört.
Aber wir altern nicht.
Ah, oí hablar de eso.
Pero nosotros no envejecemos.
Ah, había oído hablar de eso.
Pero nosotros no envejecemos.
Ah, já ouvi falar.
Mas a gente não envelhece.
А, я знаю о таких людях. 
Но у нас никто не стареет.
