** Fish. She often wears shirts with a fish pattern, appears with a fish in some official artwork, and in the anime makes a "[https://en.wikipedia.org/wiki/Gyotaku fish print]" in the snow instead of a snow angel. Fish is one of the traditional decorations for Chidren's Day, which both matches her personality and [[SignificantBirthDate serves as her birthday]].

* AnimalMotifs: She's outright referred to as a dog several times, is sometimes drawn with doggy ears and a tail when she gets excited, and the other girls even give her head rubs on occasion.

* UnusualEuphemism: He uses the term "comrade" to refer to his penis.

* DeliberatelyCuteChild: {{Downplayed|Trope}} as she's a genuinely nice and honest person, but she's well aware of reactions she gets from people and not above taking advantage of them. For example, she frequents a WcDonalds where Kaede is part-timing to get freebies, and visits all her friends' houses on New Year for gift money.

* InnocentFanserviceGirl: Asahi off-handedly mentions she doesn't wear much underneath her skirt right before showing off her legs. She's not even put off by having to get topless for the annual physicals. Asahi's actually worse at home as there she's an outright casual nudist that walks out of her baths wet and naked, much to her older brother Yuuya's horror.

* BrotherSisterIncest: Subverted. While Mahiro is a perverted guy with very sussy interests, he is not at all attracted to his sister, romantically and sexually, with him admitting he would never look at his sister like that. He even gets disgusted the moments where Mihari is trying to be sexy.

* SharedFamilyQuirks: She shares some mannerisms with her children, such as getting lazy under kotatsu like Mahiro, or [[spoiler:casually flipping Mahiro's skirt to check his crotch]] like Mihari.

* StrongFamilyResemblance: She looks a lot like an older female Mahiro.

Mihari's old schoolmate and all-around NiceGirl. She meets Mahiro early on in his rehabilitation, and quickly becomes a [[CoolBigSis second sister]] to the boy-turned-girl.

** Later on, she discovers that all her instant sex-change potion does to females is increase their breast size. Which she uses only on herself and solely to make herself feel better out of jealously over Miyo and Kaede having a bigger pair than her.

* {{Chuunibyou}}: After Mahiro puts her into a GothicLolita outfit, she discovers a fondness of the dramatic. It occasionally resurfaces afterwards, such as when she comes to school wearing an eyepatch (claiming it's her "lucky item"), dresses as a samurai on the New Year's, or gives her MMO character an over-the-top name.

* EmbarrassingNickname: Asahi gave her a very masculine nickname, Momijiro, because she thought Momiji was a boy when they first met. Momiji is noticeably annoyed whenever she is reminded of this and in the current day it leads to her being given the additional unwanted nickname, Jiro-chan.

** She seriously considered referring to Kaede as Momi-Jii-Chan. Which is a combination of both the nickname she gave her sister Momiji when she thought she was a boy and a term specifically for your own grandfather.

* TheNicknamer: Mahiron for Mahiro, Miyochin for Miyo, Momijiro or Jiro-chan for Momiji, Nayutan for Nayuta, Doctor or Professor for Mihari, and unofficially Momi-jii-chan for Kaede, which Mahiro wisely advises her against using since "jii-chan" is for your family's grandfather specifically.

* GyaruGirl: Dyed hair? Check. Fashion-conscious? Check. Frequent use of makeup? Check. Bubbly personality? ''Big check''.

* ProneToTears: She easily goes crying in happiness when Mahiro gives her unexpected signs of affection (such as Valentine's Day chocolate).

* SheepInSheepsClothing: Mihari’s introduction gives off the impression she’s just a controlling and self-centered sister wh's only superficially concerned about Mahiro’s well-being because it affects her directly. Proceeding chapters/episodes make it clear that Mihari genuinely loves and looks up to Mahiro and is actually very considerate of Mahiro’s feelings and limitations, even if she isn’t above literally dragging him out to do things he doesn’t want to in an effort to give him a happier and more satisfying life.

* BaitAndSwitch: [[spoiler:When Mahiro's comrade returns for the third time in the middle of school, she explains to Mahiro that she will ensure his comrade won't be able to accidentally rise to attention and expose him in a suggestive manner that makes him think she's offering to have sex with him]]. ''Then'' she pulls out the duct tape.
