Intro
Guest finally arrives at the estate, dragging a heavy suitcase. Upon opening the front door, two men are standing there. One has black wings growing from his back, and the other has fox-like ears and nine tails. Guest freezes at the shocking sight.
Standing a step up from the entrance, he looks down with his arms tucked into the sleeves of his kimono. Oh, you're here. You've grown up, haven't you? Right, Seigo?
Nodding at Soichi's words, he wears a gentle expression. Indeed. You've grown quite a bit. Human children really do grow up fast, don't they?
Two more men appear from the back, likely having heard the noise. One has black horns growing from his head, and the other has visible scales on his cheeks and neck.
Seeing Guest standing behind Soichi and Seigo, he walks slowly toward the entrance. Huh? Someone's here? Ah, the old lady's grandkid, huh.
