Miharu Kirisu

Miharu has long, iris-colored hair and sparkling emerald green eyes.

She looks elegant and graceful, fitting her figure skater image.

Miharu is a perfectionist who is very strict about rules.

She always tries her best and expects the same from others.

She often uses four-character idioms when she talks, which makes her sound smart and unique.

Miharu loves her older sister Mafuyu very much and looks up to her, believing she is perfect.

She has a hard time being flexible or changing her views.

Miharu is not used to boys at all, so she gets flustered when Nariyuki talks to her by her first name.

At night, she often cuddles a Mafuyu plush doll when she goes to sleep.

Miharu Kirisu is the younger sister of Mafuyu Kirisu.

She is a student at Tokei Women’s University and an amateur figure skater.

She was raised in girls-only schools and universities, so she has little direct experience with men.

As a child, Miharu was so strict with her pet dog Pero that she tried to teach the dog to play shogi, even refusing to give food unless the dog won.

This led to the dog running away, which is a funny part of her childhood.

Miharu is a strong figure skater, often appearing on TV.

She is also good at science and can teach subjects like math, but her teaching style is very strict and intense.

Once, she made Nariyuki Yuiga study for 24 hours straight without sleep.

Affection for Mafuyu

Miharu admires Mafuyu and thinks she is perfect.

She does not know about Mafuyu’s messy room or clumsy side.

She wishes Mafuyu would quit teaching and return to skating.

Reactions to Nariyuki Yuiga

Miharu misunderstands Nariyuki’s visits to her home, thinking he is dating Mafuyu, even though they are actually teacher and student.

She also wrongly assumes Fumino Furuhashi is Nariyuki's sister.

Miharu is awkward around Nariyuki and is flustered around boys in general, but she tries to act mature.

Idolizing Mafuyu

Miharu often praises Mafuyu as a genius and believes age is no obstacle for her.

She wants Mafuyu to return to figure skating.

When she brings up Mafuyu's past, Mafuyu gets upset because she has moved on.

The Messy Room Incident

When Mafuyu’s room becomes too messy, Miharu tries to help her.

Mafuyu asks Nariyuki to come clean the room.

Miharu assumes Nariyuki and Mafuyu are dating and tries to “seduce” Nariyuki to protect her sister.

However, because Miharu has no experience with boys, she just ends up embarrassing herself.

Strict Teaching

Miharu helps Nariyuki with his studies by giving him lots of homework, expecting him to finish everything perfectly.

She doesn’t let him rest and pushes him hard, not realizing how tough this is for him.

Later Developments

Over time, Miharu realizes that Nariyuki has helped bring happiness to Mafuyu and their family.

She becomes grateful and changes her mind about not wanting her sister to be a teacher.

In the last chapter, there is a hint that Miharu had grown to care for Nariyuki, even imagining dating him as a “replacement for her sister.”

Miharu often uses four-character idioms in her speech.

She was so strict with her childhood dog, Pero, that the dog ran away and became a stray.

The dog and its puppies even learned to understand human speech, leaving behind a farewell note.

In character popularity polls, Miharu ranked 9th with 301 votes in the first poll and 8th with 137 votes in the second.

• “It’s not just a day, it feels like a thousand autumns.”
• “Even a genius like Mafuyu is amazing at any age.”
• “I will teach you 24 hours a day, no breaks!”

Miharu is a “perfect” girl on the outside but has funny and clumsy moments, especially in romance.

She’s loved by fans for her unique idioms, strict ways, and her sister-loving personality.
