Dazai instructs Atsushi to capture Sigma, who holds the key to stopping the Decay of the Angels' planned terrorist attack. Sigma, meanwhile, is hell-bent on protecting the Sky Casino.
Sorrowful music runs through Sigma's veins.
.الموسيقى الحزينة تسري في عروق سيغما
In Sigmas Blut fließt die Musik der Trauer.
En su sangre corre música pesarosa.
En su sangre corre música pesarosa.
La solitude et la tristesse
coulent dans ses veines.
Una musica malinconica
 scorre nelle vene di Sigma.
Uma melodia triste corre
nas veias dele.
По его венам течёт мелодия печали.
