Synopsis
While taking a bath in a small basin, Jahy is frustrated that she has to live in a bathless small apartment in an old building compared to her old life. She recalls the Dark Realm where she had authority, magical power, and beauty, while being second-in-command and serving the Dark Lord. As she lived a good life, the Magical Girl appeared and shattered the Mana Crystal, causing the Dark Realm to fall apart. Without the mana crystal, Jahy found herself in the human world in a child form. Back at her apartment, Jahy decides to gather the shattered mana crystals and restore the Dark Realm.

After eating some beansprouts, Jahy uses a small mana crystal to temporary restore her previous form and goes to work. Working in a small tavern as waitress, Jahy is annoyed to have to use her little remaining magic for work, but she needs the money for living expenses. She also gets annoyed for serving humans instead of them serving her and also not addressing her properly. The Store Manager comes and congratulates Hy-chan on her work today and tells her she needs to smile more, which only makes her feel even more humiliated. Feeling hungry, Jahy decides to take a break. She realizes the magic is draining faster than normal and hopes she can maintain her for until she gets home, but in that moment, her magic gets undone and she turns to a small girl. Jahy starts to panic that if the owner sees her, she will get fired. In that moment, the store manager gets in the room and sees the young Jahy, but gets excited. Jahy then decides to introduce her, stating that she the Dark Lord's right hand and second most powerful being in the Dark Realm, and that she spreads calamity and misfortune wherever she goes. However, the store manager gets happy hearing she can handle the hellfires as she was getting scared of the burner. Jahy states that a human can't comprehend her power and the store manager agrees, stating she can't even imagine how much she suffered. Jahy can't believe the human isn't afraid of her and decides to kill her and take over as the new boss. She takes a fork and attempts to attack the manager, but the manager ends up hugging Jahy. As she comforts her, she gives Jahy her payment. Jahy is surprised its more than usual, but the manager explains she raised her hourly pay. She then gives her some food for home and tells her she can go home early. At home, Jahy eats some meatballs and gets happy as she haven't eaten meat in a while.

The next day, the Landlady comes to collect the rest, but Jahy refuses to pay, annoyed that she comes each month and demands it. The landlady comments that if it wasn't for her sister, the Store Manager, she would have never let Jahy stay. Jahy then comments the place is a dump and is not worth the rent. The landlady then decides to throw her out, but Jahy doesn't want to leave as she doesn't want to live again in a cardboard house by the river. Jahy agrees to pay the day after tomorrow, but the landlady doesn't agree as she said the same thing last month and then ran. Still not wanting to pay, Jahy then starts acting that she haven't eaten in two days and if she pays, she won't be able to eat. However, the landlady doesn't buy it as she knows she got pay yesterday. Jahy then wonders of a way she can escape and acts like the Store Manager is there. The landlady afraid of her sister, quickly lets Jahy, trying to explain she was just trying to collect the rent, but then sees Jahy running away.

As Jahy runs and thinks she is safe, she sees the landlady chasing her and still demanding the rent. They eventually run into the Store Manager, who then scolds both of them. The landlady states its Jahy's fault as she refuses to pay. The Store Manager then convinces Jahy to pay. Jahy admits defeat, but states that she won't pay next month and ends up again in an argument with the landlady.

Jahy is unable to find her mana crystal and states that if a human find its, it will wreak disaster that even she won't be able to stop. Guessing it may be at work, she decides to go there. The Store Manager is surprised to see her on her day off, even more in her small form. Jahy explains she came only because she is looking for a small red stone, which she needs to find at any cost and asks her for help to look for it. The Store Manager reveals she found the stone and that she believed it was Jahy's. She ended up wearing it to not forget to give it to her. Jahy gets happy that she got her stone back, but then wonders for how long was the owner wearing it. Hearing she wore it for a day, Jahy explains that the stone bestows power from the Dark Realm and in human hands it brings all manner of misfortune. The store manager gets worried that its due to the stone that she has pain in her shoulders or that she couldn't find the remote, but Jahy states that's insignificant and it should be much bigger misfortune. As nothing serious happened, Jahy wonders if her stone is just really weak. Jahy states that the stone is really important to her as she can transform in her original form with it. Hearing that, the store manager then scolds her, telling her take better care of it as she found it under the chair in the staff room. Jahy is about to thank her, but stops herself, and instead states a misfortune will be coming at her and leaves. The store manager then recalls that when she found the crystal, she put it on and tried to transform and in that moment her sister saw her and then she hit her knee, and wonder if its due to the crystal's misfortune, but was too embarrassed to tell Jahy.
