Trails of Cold Steel IV contains both my favorite moments of the Erebonia arc, and my least favorite moments of the arc. This game sold me on Fie after not really liking her for three games, but other parts of the game like the handling of past series protagonists just fell flat. Relationships between characters that were forming during Cold Steel III were offered up on the altar of the Mean Rean Machine's ever-growing harem, but at least Falcom knew to limit his conquest to characters from the Erebonia arc.
