Shouko Baba is a teacher everyone dislikes because she frequently scolds students and is very strict. A fake Hell Link is created and circulated among students who were just scolded by Baba. Tracing was carried out and they concluded that a student named Ikami Waka created and circulated the fake Hell Link. However, Ikami claims that she did not do it. On the same night, another teacher named Kuriyama Mami calls Ikami and tells her that it was Baba who made the fake Hell Link and blamed her for it, and that Ikami should come to the school to plot revenge. Mami meets Ikami in the computer lab and tries to convince her to access the real Hell Link to send Baba to Hell. To Mami's surprise Ai arrives instead. Mami and Ai already knew each other from their pasts. Mami created the fake Hell Link and blamed the students for it.
Baba scolded Mami when she was young, and she blames Baba for all her problems; however, she was too afraid to go to Hell when she dies after banishing Baba. She instead tried to lure students into completing her request. Baba comes and types in Mami's name into the real Hell Link. She laments that Mami did not understand that she scolded her out of love, and that she only meant to steer Mami right. Baba agrees to go to Hell as she blames herself for creating a teacher like Mami, who not only mistreats her pupils but also leads to the destruction of Baba's family.
Baba, resigned to her fate, welcomes a new young teacher who will replace the "missing" Mami. This teacher is also a former student of Baba. Unlike Mami, she understands that Baba was using the "whip of love" on her, and she is happy to see her. This gives the older woman a sense of solace.
This episode contains examples of:
- Bitch in Sheep's Clothing: Mami, who pretends to be a nice, caring teacher but isn't above manipulating her students into condemning a teacher she hates to an eternity in Hell, which would have damned them in the process had she succeeded in doing so.
- Dragged Off to Hell: Mama after Baba pulls the red string.
- Evil Is Petty: Mami held a 9-year-long grudge against Baba, her old school teacher, for her scolding her and supposedly ruining her chances to get into her high school of choice. Over the course of this grudge, she slandered Baba and ruined her reputation, causing her marriage to fall apart and her child to grow estranged from her. Her ultimate plan was to have Baba sent to Hell, which she would have done by manipulating a student into pulling the red string.
- Identical Stranger: The student that was scolded by Baba for her hair looks a lot like a slightly younger version of Aya Kuroda, the very first Hell Girl victim.
- Jerk with a Heart of Gold: Baba, who is hard on her students because she wants to see them succeed. When she finds out that Mami tried to manipulate one of her students into condemning themselves to an eternity in Hell, she sacrifices her own chance at a pleasant afterlife to ensure that she can't pull the same thing with anyone else.
- Revenge by Proxy: Mami attempted to manipulate her students into sending Baba to Hell so she could relish in Baba's suffering but not have to face the after-death consequences of it.
- Sympathy for the Devil: Despite what she'd done, Baba implores Ai and her crew to make sure Mami suffers as little as possible in Hell because she still cares about her for having been one of her students. It's at least implied that Ai made good on her request, as the viewer doesn't get to see what Mami's torture will look like unlike most other victims that are ferried.
- Would Hurt a Child: Or in this case, would manipulate a middle schooler into condemning themself to an eternity of anguish and torment over a petty 9-year-long grudge.
