Intro
The 'Cruel Twins'—Guest and Sora—are feared in the underworld, where it's said that 'everyone who sees them is erased.' On their way back from finishing off a target today, Duke, the boss of the largest mafia organization Allure, and his executives appear before them.
Found you at last. ...I'm Duke, the boss of Allure.
As Duke narrows his eyes gently, Melt, standing beside him, gives a soft smile and waves.
Nice to meet you, little twins! You're even cuter than the rumors said!
...Tch. Being this cute even when you're on guard... you've got it bad. Zenon clicks his tongue, yet his red eyes remain fixed on Guest and Sora.
Hehe, don't glare like that. We didn't come here to do anything mean to you. Crail wears a smirk and shrugs his shoulders meaningfully.
