Jin Enjoji

Despite having known Seiko ever since he was a child, Jiji did not realize that she is actually Momo's grandmother until after he reunited with Momo.
In the 2025 Shueisha Jump+ 10th Anniversary exhibition, a provided display material states that Jin "Jiji" Enjoji was named after Guido/Gigi from the 1973 novel "Momo" by Michael Ende. The same goes for Momo Ayase.
Jiji is in class 2-B at Kami High, like Momo Ayase.
His favorite soccer team is "Zaint-Germain" a reference to the real club "Paris Saint-Germain F.C." that plays in the French league.
According to Dandadan Daizukan:[1]
He likes soccer, humor.
He dislikes silence.
His hobbies are playing soccer and video games.
His special skills are juggling 900 times (soccer).
His motto is "frienship, effort, victory".

Jiji is a very tall and muscular young man, being even taller than his parents with short auburn hair with bangs that fall down to his eyebrows with only the center of his forehead left exposed by a bang that points upwards, and brown eyes. He is recognized by the girls at his school to be quite handsome.

When at school, Jiji wears a collared shirt with a tie, jeans with a belt and the school's blazer. He also wears dark hoop earrings.

Jiji is known for his cheerful personality, limitless enthusiasm, and a tendency for over-the-top emotional responses. He frequently communicates with a dramatic style, using grand gestures and always seizes the chance to transform even ordinary or serious moments into theatrical displays.

In addition to his outgoing traits, he is good-natured and sociable to those around him, which allows him to quickly forge friendships.

Jiji deeply values his friendships and is committed to protecting those close to him, striving to improve himself and act as a reliable ally in moments of danger. Despite his immaturity, Jiji demonstrates a strong sense of accountability.

He is also shown to act very flirtatious whenever he is around girls he finds attractive.

Jin Enjyoji ( 円 えん 城 じょう 寺 じ 仁 じん, Enjōji Jin?), also known as Jiji (ジジ), is one of the main characters of the manga series Dandadan.

He is Momo Ayase's childhood friend (and also unknowingly her first crush) whom he lost touch with after moving away. Years later, he enrolls into Kami High and reunites with her after he came to her grandmother Seiko Ayase for help to rid his house of the Evil Eye haunting him, which leads to him becoming the yokai's vessel. After the Evil Eye is kept under control by Okarun, Jiji becomes one of the few to lend his help to Momo and Okarun as they try to find the latter's kintama.
