Zizi (지지) is a zombie who attends the midnight school alike her fellow classmates.
Personality
Zizi is rather slow in movement and entirely oblivious in mind, although receiving the best grades in her class and it can be noted that she is left-handed. She is unaware of her bad smell (except in the episode, "How to Steal his Heart"), her limb and head losing habit being frightening and her slowness being annoying. She never has ill intend although she has no concepts of boundaries either. In the episode, "Birthday Boy" it is shown that her birthday is October 12th (the same day as Kebi). However, this may have been a prank.
She sleeps in a dumpster outside of the school building.
Design
Her main color is green. She wears a beche dress with pawprints on it and does not wear shoes. She has a small bandage on the right side of her chin and stitches on the side of her mouth and eyes. Her right arms is in a casket as if she has broken it. Her left wrist has stitches all around to keep her hand connected to her arm.
Regardless of stitches, she is able to fall apart without it having dire consequences.
In most episodes, she is shown to have only one tooth, which, as shown in "Wiggle Wiggle", is loose but not removable. She oddly retains all her lost teeth in other episodes, especially the ones where she bites either of her classmates.
Monstrology
The Undead are deceased humans whose hollow bodies came to move again albeit in a state of mindlessness and decomposition. "Zombie" is not the correct term for the being Zizi depicts but Western media has monstermashed the terminology due to gradual misinterpretation and terminological misuse in influential media, such as movies and video games.
Zizi is able to fall apart and is held together with stitches and bandages as her body cannot longer generate cells to fix wounds. Zizi has a bad smell and poor hygiene as well.
Her bite, like many "zombies" in modern fiction, is contagious and causes the bitten to become a zombie themselves. Whenever Zizi bites her classmates they are far more "gone" than Zizi ever shows to be.
Relationships
Cula
Zizi has a crush on Cula, much to his dislike, mostly due to her bad hygiene. She does not make a secret out of it, leaving drawings of them together on his locker and outright kissing him when she has the chance. She seems to be unaware of his dislike. Despite of this, he has had a few instances where he is more tolerant to interact with her.
Kebi
Zizi and Kebi started out as regular classmates and not shown to interact much. Kebi has gradually developed a crush on Zizi which she is oblivious to. A reasoning of him keeping distance is his awareness of Zizi's crush on Cula, which he has tried to support her in and not get in between. Still, he does nice things for her in the shadows; imagining to do it upfront but choosing to hide in the end.
Kong Kong
Zizi is a regular friend of Kong Kong and not shown to interact much nor have shown much of a specific opinion on each other.
Frankie
Zizi, when hanging out, is oftentimes shown with Frankie whom shares her lack of maliciousness. Frankie never shows much emotion although he has been annoyed by Zizi's indecisiveness and panicked with everyone else when Zizi lost her head.
