During a class assignment, a vase in the cabinet seemingly breaks by itself, but there's an elaborate plan behind it. However, this mystery is quickly forgotten when Osanai sees the bicycle thief again and plots revenge.
And he stole Osanai-san's bicycle 
because his got stolen.
وسرق درّاجة أوساناي-سان
.لأنّ درّاجته سُرقت بدورها
Da sein Fahrrad gestohlen wurde,
hat er dann deins geklaut.
y robó la bicicleta de Osanai
porque se la robaron a él.
y robó la bicicleta de Osanai
porque se la robaron a él.
Mais il se l’est fait voler,
Ma dato che qualcuno
gliel'ha rubata, ha preso la tua.
E ele roubou a bicicleta da Osanai-san
porque ela já era roubada.
И твой он украл только из-за того,
что до этого потерял свой.
แล้วจักรยานนั่นก็โดนขโมย
