Jinjin (仁々, Jinjin) is an artificial magician who was formerly experimented on. She was then rescued by Kouha Ren after being labelled as a failed artificial magician and left abandoned. She now serves him as one of his three faithful assistants along with Junjun and Reirei. She is a user of Strength Magic.
Jinjin is a short sized girl, with long straight dark hair which is tied in two pigtails in her small hat. Her bangs makes a peak shape. She wears lipstick, and has a bandage that covers her torso. She wears traditional clothing, and the edges of her dress have laces.
She's completely loyal to Kouha Ren, and she likes being hit by him. She's the quietest of the three magicians.
In some moment of her life, she, Junjun and Reirei were experimented on, and aimed to create artificial magicians, but failed. They were considered monsters, thrown away, and left to rot. Then, Kouha Ren came to them and said that he needed some magic users. He bandaged them, clothed them, smiled them, and appointed them. Since then, Jinjin and the others are in Kouha's side and serve him with loyalty.
Jinjin is in the carriage that travels to Magnostadt with Reirei and Junjun, accompanying Kouha. Just after Aladdin gets into the carriage, some bandits attack them with magic tools. Aladdin's preparing his magic to fight the bandits but Kouha's faster and strikes them. While the fight takes place, Jinjin is half hidden behind the other magicians.
After Kouha defeats the bandits, Jinjin and the other two serve Kouha. Junjun is cleaning Kouha's attire, but Kouha hits her because says that she was being careless when doing. Aladdin's alarmed, but Junjun's enjoying this and Jinjin and Reirei ask for being hit as well. Then, Aladdin, Kouha, and his assistants travel together to Magnostadt, where they separate.
Some days after their arrival to Magnostadt, the Kou's Emperor dies, and Jinjin is present when Junjun informs Kouha about this when the prince's gathered with Magnostadt Chancellor, Matal Mogamett. Kouha decides to leave, and Jinjin and the others escort him outside the academy, where Aladdin finds them. Kouha says to Aladdin that his father has died and that he's returning, but the he'll leave his three magicians in Magnostadt. The three witches are unpleased with that and doesn't want Kouha to go away.
Before the Kou Empire joins the war, Jinjin, Junjun and Reirei are with their country's army. Kouha congratulates the three magicians for their work, because since they were in Magnostadt they gave him tons of information.
After that, Kouha says he's going to use his power, and that he doesn't understand why his Djinn chose him. It appears a flashback about when Kouha obtained his Djinn, and Jinjin is showed being there too. When Kouha orders to move to Magnostadt, Jinjin and his army think that Kouha is their king.
Then, Magnostadt Black Djinn's appear and attack them, but Kouha uses his power and protects the majority of his army. Jinjin and other soldiers are sad when some of their companions are killed by the Black Djinn. When Kouha defeats the three Black Djinn, he's out of magoi, and Jinjin and the other magicians run to give to Kouha's Metal Vessel the 7th type of magic, Strength Magic. Then, more Black Djinn appear, and Jinjin and Reirei are shown to be terrified.
She joins Kouha's side when Alibaba Saluja is fighting Black Djinn and when Kouen Ren, along with his Household, appears. She stays with him all the time and when Kouen heals Kouha's arm, Jinjin is amazed by Kouen's abilities. Like others, she bows as a way of gratitude. Similarly to Junjun, Reirei and Kouha, she is very surprised when Aladdin calls Kouen an old man. She is also present when Aladdin summons Djinn of all people gathered, but doesn't say anything.
