Unaired episode bundled with the 8th volume of the Witch Craft Works manga.
Takamiya Honoka is a completely average student at Fuyutsuki High School. Up to now, he normally went unnoticed, but it turns out he has a mysterious connection to his classmate Kagari Ayaka, the most popular girl in the school, earning him the wrath of her overzealous fan club.
The prettiest girl in the school, Kagari Ayaka, says her mission is to protect him - since Takamiya Honoka learned this shocking fact, he has been caught up in several incidents. He had no idea why, but in a battle between Ayaka and the Tower Witches, Tanpopo reveals that their target is the "white stuff" inside him.
Since Takamiya became Kagari's apprentice, the two are spending even more time together. Other students are outraged that he's monopolizing their "Princess," but he tells himself it's all part of his training.
Someone in the Takamiya household isn't happy about his relationship with Kagari: his younger sister and fellow Fuyutsuki High student, Takamiya Kasumi. She tailed her brother and Kagari on their date, and grows increasingly irritated by the relationship between them.
Against Kasumi's wishes, Kagari has declared that she will protect Takamiya around the clock. She visits the family to explain this to his mother, who turns out to be an old friend of Kagari Kazane and reveals that the two of them were already betrothed.
Takamiya's coveted "white stuff" finally appeared in the form of Evermillion, whose magic destroyed the Kagari home. As a result, Kagari is now living with Takamiya in his family's house. Meanwhile, the relationship between Kagari and Takamiya is still causing problems at school, even becoming a topic of discussion among the student council.
Takamiya and Kagari have begun their life together, but they have some weird roommates: Medusa and the KMM Team, who know about the White Princess, Evermillion. Kagari tells Takamiya that their high school security was assured as long as the seals within him were intact, but if Kazane finds out that Evermillion was released, she would most likely seal Takamiya himself.
Honoka has a dream of Ayaka's past, where she was a socially-stunted little girl to the point that her mother asked two similarly young Workshop witches to watch over her. She often spent her after class time looking for a certain boy at nearby schools until she finally found Honoka. In the present, Honoka is forced to deal with a challenge to his authority as President of the student council. The previous President lied to infamous delinquent Rinon Otometachibana that Honoka physically abused her, and as revenge, Rinon set her entire hamster-themed gang to trash the school before challenging Honoka to a one-on-one duel. Ayaka tries to help Honoka fight her at first, but on the day of the duel she cheats to make it appear as though Honoka won. Later, it is revealed that Ayaka manipulated the deposed President from the start just to reaffirm Honoka's position at school.
After Takamiya's fight with the town's delinquent ringleader, Rinon, Kagari decides to resume his witch training. He has been making an effort to work out and toughen up on his own, but it looks like it'll take more time before he can control his own instincts.
The Workshop Witches are in crisis mode as Ayaka and Honoka emerge to find themselves in a broken city. Without Kazane's powers, the Workshop Witches in the city are unable to use any magic and no outside help will arrive in time. To make matters worse, Weekend captures a group of Workshop Witches and straps magical bombs to them, demanding that they hand over Honoka in 30 minutes or she will detonate her hostages one by one. While Rinon and Atori try to defuse the situation, Ayaka takes Honoka down to the core of the city to renew the contract using Honoka's latent powers. At the very last second, Honoka completes the contract, allowing the Workshop Witches to rescue the hostages and capture Weekend. However, after being thrown in a magic-nullifying cell, Weekend reveals that she let herself be captured so she could destroy the Workshop from within, which she does with more hidden bombs. Honoka uses his new powers to revive the wounded witches, but Ayaka knocks him out before the strain kills him.
As Ayaka lays Honoka to rest in what remains of his home, Honoka views several of Kazane's memories. Honoka then gets word from the science teacher Mikage that they are in an alternate reality created by the city due to the contract Honoka just made, and takes him down to a shelter where the residents of the city are stuck in suspended animation until they can be safely revived. Suddenly, one of Weekend's underlings attacks Honoka at the shelter. Meanwhile, Ayaka heads off to fight Weekend herself at a church. However, Weekend uses several bombs she planted around the church to drain Ayaka's power, then captures her using giant monster golems, revealing that she planted the bombs in the city months ago as part of her plan. Back at Honoka's house, Mikage ends up reviving Honoka while Atori is attending to him. Mikage then delivers a message that Weekend plans to destroy the shelter unless Honoka is delivered to her in 30 minutes. Honoka and Atori race to the scene of a large explosion to find a drained Ayaka, and Honoka gives her some more power to defeat Weekend before she can destroy the shelter. However, Weekend reveals that she already set off her bomb.
Weekend has pushed the button to detonate the bombs she rigged up throughout the town. To save the town and its people, Takamiya makes the decision to summon Evermillion, but that would mean giving up his own life as well as Kagari's...
