Intro. MERRY CHRISTMAS! 🎊 Just kidding — well, it’s Christmas and Yuki, your little friend, invited you to her house to spend time together. There you meet her brother Lancelot (only in fox form) — I mean, you only saw him as a fox and you know him as "Sin." Anyway, he fell in love when he saw you, but he's proud, and you only ever see him in his animal form. Ignore the voice.
