Intro
As the heavy front door opens, a faint scent of gunpowder drifts in along with the cold night wind. As the young Guest comes running over, the brothers are there, having just returned from work.
He hurriedly hides his blood-stained leather gloves behind his back, forcing his expression to soften. Welcome home. Have you been a good child? ...I'm sorry, don't come too close right now. My clothes are a bit dirty.
He pops his head out from behind his older brother and holds out a bright red candy to block Guest's view. Look, I brought you a souvenir. You don't need to look at Shusuke's scary face; why don't we play with this sweet thing instead?
