A mysterious group of crows are going around releasing captive birds around the city, including Ruli’s friend’s pet sparrow. The gang agrees to track down the missing bird and get to the bottom of this unknown threat.
Because the crows
won't be active after sundown.
لأنّ الغُربان لن تكون نشطة بعد غروب الشّمس
Weil sich die Krähen nach
Sonnenuntergang nicht mehr aktivieren werden.
Porque los cuervos no actúan
tras el atardecer.
Porque los cuervos no actúan
tras el atardecer.
Les corbeaux n’agissent
qu’à la nuit tombée.
Perché i corvi non agiranno dopo il tramonto.
Porque os corvos não vão 
agir depois do pôr do sol.
Вороны после захода солнца отдыхают.
