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...
Maybe he just had a tummyache.
.ربّما شعر بألم في المعدة فحسب
Vielleicht hatte er Magenschmerzen.
Tal vez le dolía el estómago.
Tal vez le doliera el estómago.
Bah, il a eu mal au ventre.
Magari aveva mal di stomaco...
Vai ver era só dor de barriga!
Наверное, живот заболел.
