After finishing their final exams in the basic subjects, the girls are only allowed a moment's relief before being told they're taking a "special happiness test!" Even farther underground the gym's basement facility they once visited, the girls are subjected to a virtual exam!
An even deeper underground zone!
!منطقة أعمق تحت الأرض
Da geht’s ja noch tiefer runter!
¡Es aún más profundo!
¡Es todavía más profundo!
La descente aux Enfers !
Un mondo sconosciuto, ancora più in profondità!
Uma zona subterrânea
 ainda mais profunda!
