伊野瀬 オメガ

Student at Ribun 6 Academy. Chisato's twin brother. Has amnesia. Working together with Narumi.

In truth, this is actually Miyabidou Renmaru's Sublime, while his Ego is in World A. His disguise and amnesia lead to his misidentification.

The real "Inose Omega" goes by the alias Tsutsumi Tango. (Age and birthday listed here are for Tango)
