The official website for the anime adaptation of late author Tomohiro Matsu and artist Kantoku’s Märchen Mädchen light novel series has been updated with three more cast members for the show.
I’ll introduce the new cast in this post, but I’ll also recap on previously introduced characters as well.The new cast members are as follows:

Reina Ueda as Arthur Pendragon
Arthur Pendragon is the leader of the British school. She seems like she is completely disconnected from reality, though she bonds easily with animals. She is chosen by The History of the Kings of Britain (Historia Regum Britanniae) book, specifically “The Legend of King Arthur”.

Kaede Hondo as Arika Kasumi
Arika Kasumi is Shizuka’s childhood friend. Her family has historically had a servant-master relationship with Shizuka’s Tsuchimikado family. Arika gets angry when anyone refers to her figure as childlike. She is chosen by the “Issun-bōshi” (“Little One-Inch”) fairytale.

Akemi Okamura as Headmaster
The headmaster of the Japanese school, Kuzunoha Woman’s Magic Academy. Her age is unknown, and she has the ability to mysteriously appear out of nowhere. It is unknown what her book is.
The opening theme is being performed by fhána (The Eccentric Family, Tales of Zestiria the X, Miss Kobayashi’s Dragon Maid), whilst the ending theme song will be performed by Reina Ueda.
