Adelaide Grand Marnier

Known as Hero King Adel (英雄王アデル Eiyū Ō Aderu?), she is the Legendary Hero who defeated the Demon Lord Valério Calvados and was sealed along him to keep him at bay. She is also Couvert's ancestor and wields a pistol and a broadsword in battle. She was originally summoned from France by the last princess of the Pastiage Territory, Clarifier Einz Pastillage, 100 years prior to the series. She ends her sentences with "nano desu". Before being sealed, Adel and Valeri also used to travel along Isuka and Brioche, sealing demons and keeping rogue deities from causing trouble.
