Mahiro and After the Festival (まひろと祭りのあと, Mahiro To Matsurinoato) is a special chapter of Onimai: I'm Now Your Sister. It was originally published exclusively in Collected Works Volume 7 on August 13, 2023.

Summary
At the conclusion of the summer festival, Mahiro and her friends discuss the benefits and drawbacks of wearing yukatas.

Plot
Directly after the fireworks conclude, Momiji notes that they were so pretty while Nayuta adds that the stalls were fun too. Mahiro notes lovingly that she got to see everyone in a yukata and makes a prayer sign noting that it was a sight for sore eyes. Momiji asks Mahiro who she thinks looked best in one. Mihari glances over at them while Mahiro notes that it is another loaded question.

Considering it, Mahiro says that maybe it was Asahi since she had the element of suprise with a large amount of gap moe. Asahi notes in delight that Mahiro is making her blush while Kaede laughs saying that she totally agrees.

Mahiro tells Kaede that she obviously looks great as well. Kaede thanks Mahiro for saying that, but adds that her chest is a bit off, as she thinks she looks better without a yukata since she's flat with one on. Miyo says that kaede is pulling off the look perfectly, and Kaede thanks her for saying that. All the while, the flat chest squad get all gloomy due to not being able to share in the experience.

Mahiro suddenly realizes that now that she's taken a closer look, Kaede's bust does look much flatter than usual. Asahi panics and asks her and Miyo if they cut them off, to which Miyo insists that they didn't. Kaede explains that she uses shapewear to flatten them, while Miyo says that she wraps a towel around her torso to straighten out her curves. Mahiro notes that it sounds painful, and Nayuta explains that it's tough when they're big, speaking from experience.

Momiji is amazed that even if you wear a yukata you still need underwear. Mahiro becomes shocked by that statement andf asks Momiji what she meant by that just now. Momiji is also suprised, and reiterates her belief that you don't need to wear anything underneath a yukata, asking if she's right. Kaede says that that's a thing of the past. Mihari says that it'd make sense if they were at a ryokan or something, with Miyo saying that outside is a bit much.

Momiji immediately blushes furiously and covers her private area with her hands. Mahiro is shocked that there's apparently nothing underneath, especially since Momiji is als wearing an easily removeable men's yukata. Momiji starts crying, asking Kaede why she didn't tell her. Kaede admits that she never thought that she'd have to.

Asahi tells Momiji to take it easy, and Momiji feels better. Asahi gives Momiji a thumbs up saying that she can't see what isn't there, which makes Momiji furious at her.
