Arisa Izayoi

Arisa Izayoi is a bunny girl character from the in-story series “This Is Tsukiyono Company” within My Dress-Up Darling.

She wears a black bunny suit combined with a tailcoat-style outfit, giving her a stylish yet eye-catching appearance.

She is perceived as a cool-type character at first glance, but she is actually clumsy and very caring toward her fellow bunny girls.

Because of this contrast, she is seen as a gentle, considerate “good girl” despite her sharp visual design.

In My Dress-Up Darling, Marin Kitagawa affectionately calls her “Arisha.”

Marin likes her so much that she can perfectly recite Arisa’s lines from the scene where Arisa first puts on the bunny suit.

Arisa’s standard costume in “This Is Tsukiyono Company” is a black bunny suit paired with suspender stockings.

Among the three bunny girls of Tsukiyono Company, she stands out for her cool aura balanced with endearing blunders.

Her voice actress is Miyuri Shimabukuro, who brings out both Arisa’s composed side and her clumsy charm.

In-universe origin

Within the world of My Dress-Up Darling, “This Is Tsukiyono Company” is a fictional series that Marin is obsessed with.

Arisa Izayoi is one of its three main bunny girl protagonists, employees of the in-story “Tsukiyono Company.”

The bunny suit functions as the official company uniform for the characters in that series.

In episode 1 of “This Is Tsukiyono Company,” Arisa has an outburst of dissatisfaction when she learns that the bunny suit is their actual uniform.

Her outfit is not just a simple bunny suit; it mixes elements of a tailcoat with the bunny design.

This fusion gives her a more formal, stage-performer look while still being very revealing.

Marin Kitagawa’s favorite character

In My Dress-Up Darling, Marin is deeply attached to Arisa and calls her “Arisha” as a nickname.

She loves Arisa’s debut bunny-suit scene so much that she can copy the lines from that scene word for word.

Marin later asks Wakana Gojo to create Arisa’s bunny suit so she can cosplay her.

This request leads directly into one of the series’ most memorable cosplay production arcs.

Wakana’s initial assumptions

Wakana Gojo initially believes that Arisa’s bunny costume will be easy to make.

Compared to his previous complex commissions, the bunny suit looks straightforward and not very elaborate.

However, when he actually starts building the outfit, he runs into a serious issue with the chest area.

No matter how closely he reproduces what he saw in the anime, the fabric at the bust keeps slipping down.

Marin proposes some alternative ideas to fix the problem, but Wakana is not satisfied with any of them.

He feels that none of their quick fixes solve the issue in a structurally sound or convincing way.

Advice from Akira Ogata (Usami)

Stuck on the chest problem, Wakana consults Akira Ogata, a clerk at a handicraft supplies store and an experienced costume maker.

Akira quickly tells him that if he inserts boning (a stiff core material) into the chest area, the fabric will not collapse or slide down.

This solution is something Wakana technically already knew, since he had used boning before.

Realizing he failed to recall such a basic technique, he becomes painfully aware of his own overconfidence and lack of proper research.

He recognizes that he had assumed he could make the costume easily without studying it thoroughly.

Feeling ashamed, he reflects on how complacent he had become as he progressed in his craft.

Marin’s reaction to the chest fix

When Marin hears from Akira that properly constructed bunny suits do not have their chest sections slip down, she is stunned.

She blurts out something along the lines of, “So it doesn’t flip down like it does for Arisha!?” and becomes visibly disappointed.

Her disappointment comes from her unique emotional “trigger points,” where she gets excited about oddly specific or niche details.

This sudden reaction leaves both Wakana and Akira bewildered, as they cannot quite follow why that aspect matters so much to her.

Marin’s comment humorously underlines how her admiration for Arisa extends to very particular and even problematic costume moments.

It also highlights how invested she is in reproducing not only the look, but the feel and drama of the original scene.

After incorporating boning and other adjustments, Wakana successfully completes Arisa Izayoi’s bunny suit for Marin.

The end result is a highly accurate cosplay that captures the visual impact of the in-universe character.

However, a new issue appears once the suit is finished: the extreme high-cut design around the hips.

The high-leg cut is so daring that even Marin, who is usually bold, hesitates to wear it directly on her bare skin.

To address this, Marin comes up with what she thinks is a considerate plan so as not to trouble Wakana.

She decides to wear ultra-small adhesive-type underwear combined with layered flesh-colored stockings as a “coverage” measure.

From Marin’s perspective, this counts as sufficient modesty and a serious effort to reduce skin exposure.

From Wakana’s point of view, though, the flesh-tone stockings look almost exactly like bare skin, making the outfit just as intense.

Because of this, he finds it extremely hard to keep his composure during the photo shoot.

Normally he can stay focused behind the camera, but in this case his inner turmoil is at its peak.

The photo session itself takes place in a studio recommended by Ito Suzuka, who enjoys cosplay photography.

Thanks to the realistic setting and Wakana’s detailed craftsmanship, Marin’s Arisa cosplay turns into a visually striking shoot.

The Arisa bunny suit is not a one-off costume; Marin uses it again for a Halloween cosplay event.

The outfit’s quality draws a lot of attention, and she quickly becomes a focal point among the crowd.

However, the event is held at night, at a time of year when it is already quite cold.

Walking around outdoors in a revealing bunny suit during chilly weather has predictable consequences.

After the event, Marin ends up catching a cold.

This small epilogue adds a slice-of-life touch to the arc, showing the less glamorous side of wearing such a daring costume in real conditions.
