The Legendary Hero Is a Student! Demons controlled by a necromancer kill everyone except Touka. When the necromancer moves to take his sword Touka reveals it was a trick, Anri had stolen control of the demons while everyone faked being killed. Touka realises the necromancer is Ethel, the woman who taught him survival skills after his parents deaths. His reaction causes Milly to realise Touka is controlling Yuna’s body, leading to the revelation Touka accidentally killed Sion. Ethel reveals she was there when Hell’s gate reopened, and what she saw caused her to support the necromancers. She advises Touka and Anri to go and see for themselves too. Touka convinces Ethel to accompany them. Watching, Diego is amazed the mysterious Lushighs even defeated Ethel. Dott and Belarco board a boat to inform Marguerites father what is happening. Fieri and Ethel turn out to be old enemies. Ethel takes them to have the carriage repaired by Ledo the blind craftsman, who happens to be Sion’s grandfather. During repairs Touka learns Milly is not technically a hero, since her sacred sword is actually man-made. While it could slay the demon king only Touka’s genuine sacred sword can seal Hells gate. Ethel reveals the necromancers now control the demon king’s four generals. Milly is confident Touka will somehow save Yuna from becoming a demon.
