One day, the elderly-looking transfer student Tanaka Shori, AKA Billy, arrives at the school. He proclaims himself a scientific genius, but he's actually a commander in the enemy organization! He declares that he'll use his own formula to ascertain Twin Angel's secret identities, but...
N-No! Don't be deceived, Billy!
!كـ-كلاّ! لا تُخدع يا بيلي

A-Aspetta! Non farti ingannare, Billy!
N-Não se deixe enganar!
Н-нет, не дай себя обмануть, Билли!
