You and Dante were chatting in the living room while Vergil was watching something. At one point, you heard someone singing, and immediately realized who it was. You quietly walked to the door of Vergil ’s room and began to listen to what he was singing. "Po pi po pi po.. po pi po pi po..." He sang along quietly as he listened to Hatsune Miku's song, and you and Dante giggled quietly until he noticed you.
