Jahy, the feared and respected number-two ruler of the Dark Realm, suddenly finds herself powerless and shrunken in the human world after a magical girl destroys a powerful mana crystal, which also destroys her home realm. The manga follows Jahy and her daily life as she learns to live in her new surroundings while she works to restore her original form, the mana crystal, and the Dark Realm.
- Jahy (ジャヒー, Jahī)
- Voiced by: Naomi Ōzora[6] (Japanese); Lisette Monique Diaz[7] (English)
- Jahy is the former aide to the Dark Lord and second-in-command of the Dark Realm, who is now living in the human world after the Dark Realm perished. She aims to find parts of the mana crystal and restore her home world and her original body, which is in a child-like state after the crystal was destroyed by a magical girl, leaving her powerless. Though she struggles to adapt to her new surroundings and her current state, she remains confident, vigorous, and ambitious.[8][9] Later on in the series, she establishes her own restaurant, but leaves Druj to run it.
- Druj (ドゥルジ, Duruji)
- Voiced by: Kana Hanazawa[6] (Japanese); Monét Lerner[7] (English)
- A former subordinate of Jahy's who goes by the name Nana Dojima (堂島 ナナ, Dōjima Nana) in the human world. She is the president of a consulting company. Even though she lives elegantly in a high-rise condominium while Jahy lives in squalor in a decaying apartment building, she nonetheless remains friendly with Jahy and regularly hangs out with her. She enjoys being berated and treated as subhuman by Jahy.[8][9]
- Boss (店長, Tenchō) / Chisa (ちさ, Chisa)
- Voiced by: Ai Kayano[6] (Japanese); Natalie Rose[7] (English)
- The manager of the pub Sōsaku Izakaya Maō. (創作居酒屋まおう。, transl. "Craft Pub Maou."), where Jahy works. Often displaying a sort of motherly tenderness, she is very friendly with Jahy and gives her the nickname "Hy-chan" (ひーちゃん, Hī-chan).[8][9]
- Landlord (大家, Ōya) / Ryou (涼, Ryō)
- Voiced by: Yoko Hikasa[6] (Japanese); Suzanne DeCarma[7] (English)
- The landlady of the apartment where Jahy lives, and the sister of the pub manager. She constantly pesters Jahy about her rent, though ultimately cares about her (albeit with a very tsundere attitude). Similarly to her sister, she nicknames Jahy "Jako" (ジャー子, Jā-ko).[9]
- Kokoro Sasaki (佐崎 こころ, Sasaki Kokoro)
- Voiced by: Yui Ogura[6] (Japanese); Brooklyn Wade (English)
- An elementary school student who helps Jahy on her quest to find mana crystal shards. She exudes an extreme amount of kindness and praise for Jahy, which compels Jahy to befriend her.[9]
- Kyouko Jingu (神宮 きょうこ, Jingū Kyōko) / Magical Girl (魔法少女, Mahō Shōjo)
- Voiced by: Sumire Uesaka[6] (Japanese); Brittney Karbowski (English)
- The magical girl that destroyed Jahy's home world, who later works at the same pub as her. She was originally an ordinary high school girl, but set out as a magical girl to save others from their misfortunes after a mysterious light bestowed a mission to her as she nearly drowned to death. As a result of collecting the same mana crystals as Jahy, she experiences regular bouts of incredibly bad luck. She eventually becomes friendly with Jahy and does not get along with Druj because of this.[8][9]
- Saurva (サルワ, Saruwa)
- Voiced by: Mikako Komatsu[6] (Japanese); Brittany Lauda (English)
- An elaborately-dressed girl who aims to take Jahy's spot as the number-two ruler of the Dark Realm. Although she is talented and thorough with inventing and planning strategies, she is careless and her efforts prove fruitless.[9]
- Demon Lord (魔王, Maō)
- Voiced by: Miho Okasaki[10] (Japanese); Krystal LaPorte (English)
- The Demon Lord of the Dark Realm who revived in a smaller form in Kyouko's house due to the mana crystals she had amassed. A non-talkative demon who has a blank expression on her face at most times, she is an incredible glutton, often eating large amounts of food.[9]
- Su (スー, Sū)
- Voiced by: Akari Kitō (Japanese); Celeste Perez (English)
- The Demon Lord's younger sister, whose attempt to reconcile with her sister by turning Kyouko into a powerful magical girl accidentally resulted in destroying her and the Dark Realm. Thus, she went around as a mysterious light and began using magical girls to try and gather the mana crystals for her.
