Nephelia

From Galaxy Angel Wiki, the comprehensive Project G.A. reference.

Nephelia
Gender:	Female

Formerly Lezom's first officer, she turns out to be the leader of a Val-Fasq starfleet that invades Transbaal territory in Moonlit Lovers. She pursued Takuto and the Elsior throughout most of the game. She is voiced by Kaho Kouda (幸田夏穂).

After Lezom is defeated for the last time partway through the game, Nephelia publicly reveals herself as a Val-Fasq, and she uses an overkill strategy by having a "hive"-like ship deploy legions of small ships at once so they can overwhelm the Elsior and the Angel Frames. Lezom is at first elated at his first officer's success, but Nephelia then proceeds to activate (from her ship) a self-destruct mechanism on Lezom's warship, which eventually leads to the latter's death (although Lezom still has time to express outrage and then beg for his life first before his ship explodes). Nephelia's strategy is thwarted only because the protagonists are able to activate the Elle Ciel's Chrono Drive and escape. Nephelia is shown to have a penchant for cruelty and apathy; at various points in the game, she laughs as she makes the protagonists suffer, and she is somewhat smug when explaining to Lezom her reasons for killing him. Nephelia's ship is surrounded by an almost-impenetrable shield, and Takuto's first attempt to destroy it with the Chrono Break Cannon proves fruitless. However, when Takuto and his chosen Angel, in the final battle of the game, are able to maneuver the Elsior close enough to Nephelia's ship, they use a device to cancel out the shield, and then successfully destroy Nephelia and her ship with the Chrono Break Cannon.
