Marin Kitagawa — My Dress-Up Darling

At the school cultural festival, Marin represents her class in a pageant that calls for crossplay and chooses Rei Kogami, a male character. Presenting that role convincingly requires her to rethink how she moves and poses, while Gojo works on the outfit under the pressure of classmates’ expectations. The class’s collective effort widens Gojo’s social world, and Marin’s performance demonstrates that her love of cosplay is not limited to female characters or familiar looks.

Marin takes on more part-time work to buy a DSLR camera, then attends an event in the role of photographer. Her circle grows to include cosplayers with experience in props, group staging, and specialist make-up. The horror-game Coffin group shoot brings several of those contacts together, including JuJu. Alongside the excitement of the shoot, Marin is carrying feelings for Gojo that she finds unexpectedly difficult to say aloud.

The pair undertake an exceptionally demanding new project: Marin’s portrayal of Haniel from Heaven’s Will. Gojo devotes enormous attention to the costume, and her appearance at Winter Comiket draws an extraordinary crowd. Photographs spread widely online and reach the fictional work’s original creator. What should be their shared triumph becomes emotionally painful: Gojo’s downcast reaction and their uncertainty about what the attention might mean for their partnership create a serious distance between them.

After the Haniel cosplay attracts intense attention, Marin worries that continuing to rely on Gojo for costumes may be causing him pain. Their uncertainty grows as someone from Gojo's past unexpectedly reappears during an outing connected to hina dolls. When the two finally confront the feelings they have struggled to express, they acknowledge that their affection is mutual and begin dating. The change comes through a conversation they had been avoiding, not through the public success of the costume itself.

Marin and Gojo begin experiencing their relationship openly rather than only through costume projects. The final volume includes a birthday date for Gojo, a disagreement over behavior during that date, and a return to a beach that has personal meaning for them. Their new status changes the stakes of ordinary outings: they must reconcile different comfort levels and expectations while remaining the creative partners who first met over sewing and cosplay.

Chapter 115 moves forward several years and shows Marin and Gojo as a married couple living with Gojo's grandfather. Their wedding is not shown as an on-page ceremony; wedding photographs and Marin's ring establish what has happened. Marin has become a successful professional model, while Gojo continues his work as a hina-doll craftsman and receives recognition on television. The chapter closes with a family meal, bringing their once-separate households and interests into an ordinary shared life.

A supplementary story included in Volume 15 looks back to the period before the wedding: Marin and Gojo visit her father to tell him they plan to marry. Marin approaches the visit cheerfully, while Gojo is visibly nervous. This episode fills in part of the path to the marriage already shown in the main finale, rather than replacing its ending.

The engagement story also puts Marin's consideration for Gojo into everyday terms. She wants to adjust her modeling workload and take on more housework so that he can concentrate on making hina dolls, but her cooking skills are not ready for the plan. Her father and Gojo step in to help her practice. The scene balances a comic domestic mishap with a concrete effort to support his work.

The final volume's epilogue, set after their marriage, introduces Marin and Gojo's daughter, Nichika (日嘉). Marin, Gojo, and Nichika visit Marin's father, Masumi, for his birthday. Nichika has made him a gift but becomes too shy to present it; Gojo takes the time to listen to her hesitation. The scene gives their future family its own small, character-specific moment rather than ending with the fact of the marriage alone.
