There is a continuity error with Shanoa from Castlevania: Order of Ecclesia. Her storyline states she is still looking for Albus when she enters the Time Rift but she uses Dextro Custos and Sinestro Custos (twin biting Cerberus heads) that can only be found in Dracula's Castle after defeating Albus in Mystery Manor.

Aeon's hyper attack contains unique dialogue for each character.
