Yoko Tsuno Vol. 14: The Archangels of Vinea (The Archangels of Vinea) - Roger Leloup

When a suspended animation pod with a child inside washes ashore on an isolated island of Vinea, Khany is dispatched to investigate - and takes Yoko along with her. The trail leads Khany to a strange tower that emerges from the water at regular intervals. But by the time Yoko follows suit, Khany has disappeared, the tower begins to sink again, and a mysterious, angel-faced Vinean is about to be shot by men who appeared from beneath the waves.
