The story begins with the protagonist, Dennis Bataille, a Marquis, reflecting on his life five years after his transmigration into the world of "Witchcraft Academia." Initially, he enjoyed a peaceful life, believing himself to be a mere mob character. However, his perspective drastically shifts when, ten years after his transmigration and five years after his wife's death, he receives a marriage proposal from Duke Berge for his son, Dirk, to be betrothed to Dennis's daughter, Alise. This proposal triggers Dennis's memories of the game's plot, revealing that Alise is destined to become an "evil noblewoman," face annulment, and be executed.
Driven by a desire to protect Alise, Dennis decides he must raise her to be a kind and strong individual capable of avoiding her tragic fate. He abandons his work to spend more time with his three-year-old daughter, initiating a daily routine of playing with her in the garden. During one such afternoon, Alise expresses a desire to become strong like her father, leading them to practice sword swings together. This shared activity deeply moves Dennis, reinforcing his resolve to protect her.
Two years later, Alise is nearing her fifth birthday and her debut into high society. Their daily sword practice has evolved into mock battles, showcasing Alise's exceptional talent as a swordswoman. The impending engagement with Duke Berge's family looms, and Dennis intends to prioritize Alise's wishes. However, when he tentatively brings up the topic of engagement, Alise declares her desire to marry him instead, revealing a surprising and unsettling attachment.
As Alise's fifth birthday approaches, Dennis presents her with a "World Tree Jewel," a powerful artifact capable of sacrificing itself once to save its wearer. The next day, at Alise's grand debutante ball, she stumbles and cries out in distress. Dennis rushes to comfort her, prioritizing her emotional well-being over social decorum. The Duke, impressed by Dennis's handling of the situation, hints that Alise's reaction is not uncommon among young debutantes.
Later, Dennis and Alise embark on a trip to the city. During their exploration, Alise innocently points out a ragged boy and asks why he is so dirty, implying he should buy new clothes. Dennis, startled by her insensitivity, scolds her, which leads to a tense exchange with the boy, who reveals the clothes are his deceased mother's last possession. Alise, deeply affected by this revelation and her own lack of a mother, apologizes sincerely. Dennis, realizing his own harsh reaction was inappropriate, vows to be a better parent.
The following day, Dennis confides in his butler, Sebas, about his parenting struggles. Sebas advises him that strictness, like kindness, is a form of love, prompting Dennis to reconsider his approach. Before he can speak with Alise, a maid rushes in to report that Alise is missing.
