While only a guest character in Zero no Kiseki and playable on one occasion, Noel becomes a full party member in the sequel and plays an expansive role in its story.
Noel is a sergeant in the Crossbell Guardian Force -CSGF-, and elder sister to Fran Seeker. She assists the SSS on multiple occasions, usually in the form of providing transport and mission briefings to the team when undertaking missions from the CSGF. The party also spars against her on several occasions when requested by the CGSF.
Her weapons of choice are a pair of orbal sub-machine pistols.
