Airi Arcadia is a character from the Saijaku Muhai no Bahamut light novel and anime.

Lux's younger sister. She seems to love him more than a sister normally should, but she's not afraid to berate him. She also dislikes it when Lux puts himself in harm's way or if he is constantly pushing himself for her or someone else. She also tells anyone within hearing range about her brother's abilities (usually Noct) whenever he's in an important combat. She does her part to help pay for their family's debt to the New Kingdom by working as a researcher and scholar of the ruins within the academy.

In the XP4 fics, Airi is a member of the Heroes Coalitions and is an honorary member of the Cross Guards. She also attends the Vanguard Academy as a student.

In the TWA fics, Airi debuted in the Twisted World Animania - Undefeated Bahamut Chronicle.
