On a misty night, Oda Sakunosuke, Dazai Osamu, and Sakaguchi Ango meet as always at their usual bar. For the trio of Port Mafia members, it a night spent in camaraderie like any other, but Ango vanishes that very night. Oda is given a direct order from the Port Mafia boss to find Ango, but...
He may have chosen to vanish 
of his own free will,
،لربّما اختار أن يختفي بمحض إرادته
Ob er absichtlich
untergetaucht ist
Pudo desaparecer por voluntad propia,
Pudo desaparecer por voluntad propia,
On ne sait pas encore
s’il a voulu fuir
Potrebbe aver deciso
volontariamente di scomparire,
Pode ter sumido por livre e espontânea vontade
Он мог исчезнуть по собственной воле,
