Kuroki wants badly to rehabilitate Mythos, the young boy caught up in the Logos incident.  When an unmanned bike starts making strange appearances on the roads of Tokyo, he sees his chance to allow Mythos to contribute to society by solving the mystery.  The bike appears and disappears without causing any harm or hurting anyone.  But Mythos thinks that instead of a bored thrill-seeker, the culprit might be a more dangerous foe...
It races along for a while and disappears.
.إنّه يُسابقنا لبعض الوقت ثمّ يختفي
Düst in einem Affentempo rum und
verschwindet auf einmal wieder.
Corre un rato y desaparece.
Corre un rato y desaparece.
Il ne fait que foncer, 
puis disparaît soudainement.
Corre per un po' e poi scompare.
Corre por um tempo e depois some.
