Chiya's Grandma

Chiya's Grandma appears in Koi’s series Is the Order a Rabbit?, which features a cast of girls working in cafes and sweets shops.

She represents the traditional Japanese-style sweets side of the town’s café culture, balancing strict professionalism with hidden warmth.

In the anime adaptation, she first appears in season 2, episode 9.

Her role is expanded significantly in season 3, Is the Order a Rabbit? BLOOM, where she interacts more with the main cast.

She manages the sweets shop and tea house Ama Usa An in place of her daughter Chidori, who travels as a sweets buyer.

She works alongside her granddaughter Chiya, helped by several part-time workers.

Her real name has not been revealed in the series so far.

She is sometimes referred to in-universe with fear or respect because of her harsh way of speaking and strict demeanor.

Chiya's Grandma is loud, blunt, and often verbally harsh, which leads people to describe her as scary or even monstrous.

During Chiya’s childhood, people around her reportedly called the old woman a “demon hag,” and Syaro Kirima is shown to be afraid of her.

Despite the rough exterior, she is fundamentally kind and caring.

She is quick to scold and quick to snap back, but she quietly looks after the younger characters and supports them in her own way.

A good example of this softer side appears when Chino Kafu works at Ama Usa An as part of a workplace experience program.

Although she treats Chino strictly while working, she secretly brings her sweets and tea, telling her to “take as long a break as you like” and “relax,” showing clear affection.

She also tends to hide her kindness behind grumbling or teasing remarks.

This contrast between her words and her actions is a key element of her charm and comedy in the series.

As the manager of Ama Usa An, Chiya's Grandma represents the older generation of traditional sweets makers.

She trains and guides Chiya in running the shop, passing down both skills and values.

When Chino participates in a work experience program at Ama Usa An, Chiya's Grandma supervises her with strict instructions.

Even while barking orders, she pays close attention to Chino’s effort and offers snacks and rest to support her.

She occasionally interferes in the younger girls’ antics with decisive, no-nonsense actions.

For example, when Chiya and Syaro argue over who gets to style Megumi Natsu’s hair, she suddenly steps in and gives Megumi a straight perm, ending the argument in her typical over-the-top fashion.

Her presence adds a grounded, adult perspective to the otherwise light and fluffy atmosphere of the series.

At the same time, her exaggerated “scary grandma” traits are used for humor and to highlight the kindness she keeps hidden under the surface.

Chiya Ujimatsu

Chiya's Grandma is Chiya Ujimatsu’s grandmother and guardian within the shop.

She runs Ama Usa An together with Chiya, teaching her about traditional sweets, customer service, and business.

Chiya remembers calling her an “ogre-like old woman” when she was small because of her strictness and rough words.

Nevertheless, their bond is close, and Chiya clearly respects and loves her grandmother.

Chiya often explains her grandmother’s surprising talents to others, such as her skill with blow darts.

Through Chiya’s perspective, the audience sees both the fear and admiration she feels for this strong-willed woman.

Chidori (Chiya’s Mother)

Chidori is described as the daughter of Chiya's Grandma and the mother of Chiya.

She works as a buyer of sweets, traveling to various places to discover and purchase confectionery.

Because Chidori is often away from home, Chiya's Grandma takes charge of Ama Usa An and the family business.

She effectively acts as the central pillar of the shop and the household in Chidori’s absence.

Chino Kafu

Chiya's Grandma has a notable connection to Chino Kafu through Chino’s work experience at Ama Usa An.

While she initially appears stern and intimidating to Chino, she soon reveals a caring side through small gestures of consideration.

She comments that Chino’s habitual serious and expressionless face reminds her very much of Chino’s grandfather.

This remark ties Chino directly into the older generation’s long-running dynamic of teasing and rivalry.

Chino Kafu’s Grandfather

Chiya's Grandma has a long-standing, comedic rivalry with Chino Kafu’s grandfather.

Whenever they meet, they immediately launch into shouting matches, calling each other things like “old man” and “old woman.”

She describes him as someone who “did not like monaka (a type of bean-filled wafer sweet)” and as “greedy.”

Despite the harsh descriptions, their interactions feel more like old friends bickering than true enemies.

She even jokes to the younger characters that it would be troublesome if that “old man” came back as a ghost.

The tone of these comments suggests the classic “fight because they are close” dynamic rather than genuine hostility.

Syaro Kirima

Syaro Kirima is frightened by Chiya's Grandma and her harsh manner of speaking.

Her nervousness around the older woman is often played for comedy.

Despite this, Chiya's Grandma does not show any actual malice toward Syaro.

Her frightening aura is mostly a matter of perception influenced by her sharp tongue and intimidating energy.

Megumi Natsu

Chiya's Grandma interacts with Megumi Natsu during a scene where Chiya and Syaro argue over styling Megumi’s hair.

She interrupts their quarrel and, without much ceremony, gives Megumi a straight perm.

This sudden intervention demonstrates both her decisiveness and her tendency to dominate a situation.

It also adds to her image as someone who does things her own way and does not get bogged down in the younger girls’ petty disputes.

Chiya's Grandma is implied to be a highly skilled traditional sweets artisan through her role at Ama Usa An.

She is responsible for maintaining the quality and reputation of the shop that specializes in Japanese-style confections.

According to Chiya, she is also a master of blow darts.

Ama Usa An even has a full set of blow dart equipment stored there, an odd but humorous detail that emphasizes her unexpected and somewhat dangerous talents.

Her combination of culinary expertise and bizarre side skills makes her stand out among the adult characters.

These elements are usually treated comedically, showing her as both reliable and slightly terrifying.

In the anime adaptation of Is the Order a Rabbit?, Chiya's Grandma is voiced by Miyuki Ichijo in earlier appearances.

Her casting for later or future productions has not been definitively stated in the provided material, leaving subsequent casting information unknown.
