While taking their usual bath, the boys discuss how much Kyotaro is like an old man. The next day, when they go to school, they find themselves exhausted by climbing up the stairs... and learn that they're all becoming old men!
Spread fear! Rise, Black Knight!
!انشر الخوف! ارتقِ أيّها الفارس الأسود
Esparce el temor.
Levántate, Caballero Negro.
Esparce el temor.
Levántate, Caballero Negro.
Diffondi la paura! Alzati, cavaliere nero!
Espalhe o medo!
 Levante-se, Cavaleiro Negro!
Сей страх! Восстань, Чёрный рыцарь!
