The Ranker has mousy brown hair, fair skin and black sclera with red irises. He has three lines that extend from the outer corners of his eyes that end in vaguely heart-shaped bits as well as vaguely heart-shaped earrings. He wore purple and grey garments.
He was seen floating above the tail of the Archimedes and began to tip the container on the ship's tail in order to pour the solution down into the cavern where the Thorn had been. While pouring, he was intercepted by and briefly battled Lero-Ro. However, he was called away by Madoraco but not before telling Lero-Ro that he would kill him if they met again.
He had the ability to float using Shinsoo and was strong enough to fight Lero-Ro on a somewhat equal standing. He was seen in possession of a sharp weapon which might have been either a sword or a needle (it wasn't clearly shown although it is most likely a sword, according to how he swung it). He was able to launch pink crystal-like attacks with it.
