Poseidon and Shu joined Aether Gazer around the same time and are good friends. Poseidon is milder and easy-going in contrast to the serious, intellectual Shu, which is probably how Poseidon ended up rejecting a promotion to the position of manager of Division Nine for reasons of "poor fit," and recommended Shu for the position instead. After the end of the management selection, Poseidon no longer participates in other affairs of the Aether Gazer except for carrying out missions. Poseidon likes to holiday at the beach alone, even if just to sunbathe while soothed by the gentle sea breeze, an activity she finds extremely satisfying. Even Shu is unsure exactly what Poseidon sees in those vast oceans behind those clear blue eyes.

Poseidon's Divine Power is one of the few that can repair Modifiers' core data in battle. The Cryptics used the legendary trident as a model to design an Access Key to help Poseidon control this energy better. A beautiful sound like a wave is emitted occasionally when the Divine Power is used, so it got the name Tidal Song.
