Lord El-Melloi II-sei no Jikenbo: "Rail Zeppelin" Grace note Tokubetsu-hen

A letter arrives for Lord El-Melloi II, announcing a Clock Tower reunion. As the event approaches, he looks in the mirror and is startled to see himself as he was ten years younger. He has reverted to his past self, Waver Velvet. Thinking it may be a powerful magical illusion, he starts an investigation into the cause. On the day of the reunion, he attends the gathering with the intention of confronting whoever altered his body and uncovering their motives. However, the arrival of Touko Aozaki leads to unexpected developments.
