The How NOT to Summon a Demon Lord anime is on the way this summer season with its adaptation of the light novel series written by Yukiya Murasaki and illustrated by Takahiro Tsurusaki. Ahead of that, three more cast members have been added to the lineup.
Ryōtarō Okiayu plays the human Emile Bichelberger, a level 50 member of the Adventurers Association of Faltora City. He fancies himself a nice guy and an ally to all ladies, but he’s really kind of deplorable.
Akira Ishida plays the elf Keera L Greenwood, an experienced flautist who follows his younger sister Shera around.
Akio Ōtsuka plays feudal lord Chester Ray Galford, a human of an unknown level who fought against the Demon tribe around 30 years ago.
J-Novel Club publishes the original novels in English. Here’s how they describe the story:
In the MMORPG Cross Reverie, Takuma Sakamoto is so powerful that he is lauded as the “Demon Lord” by other players. One day, he is summoned to a world outside his own– but with the same appearance he had in the game! There, he meets two girls who both proclaim themselves to be his Summoner. They perform an Enslavement Ritual to turn him into their Summon… but that’s when Takuma’s passive ability <<Magic Reflection>> activates! Instead, it is the girls who become enslaved! Though Takuma may be the strongest Sorcerer there is, he has no idea how to talk with other people. It is here he makes his choice: to act based on his persona from the game! “Amazing? But of course… I am Diablo, the being known and feared as the Demon Lord!” So begins a tale of adventure with an earth-shakingly powerful Demon Lord (or at least someone who acts like one) taking on another world!
