The Sket-dan is challenged to a battle of wits by Enigman, the masked President of the Quiz Club (and his lovely assistant Quettion). Later, a drop-dead gorgeous second year comes to the Sket-dan to ask for advice... about love? Can the Sket-dan unravel the enigma of love?
I mean, your mask! I've seen your face now!
¡Es que tu máscara! ¡Puedo ver tu rostro!
¡Es que... tu máscara!
¡Ahora te he visto la cara!
Digo, sua máscara! 
Eu vi seu rosto agora!
