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...
Didn't you infiltrate the school saying you'd 
learn Twin Angel's identity within a week?
ألم تتسلّل إلى المدرسة قائلاً أنّك ستكتشف 
!هويّة توأم الملاك الحقيقيّة خلال أسبوع؟
Meintest du nicht, du findest in einer
Woche raus, wer die Twin Angels sind,
¿No te infiltraste
para descubrir la identidad
¿El plan no era descubrir la identidad
de las Twin Angel en una semana?
Ça fait une semaine
que tu cherches les Twin Angels.
Non avevi detto che ti sarebbe bastata una settimana
per smascherare le Twin Angel?
Não disse que acharia a identidade
secretas das Twin Angels em uma semana?
Ты ведь сказал, что проникнешь в школу 
и вычислишь ангелов-близнецов за одну неделю?
