History Manga / KoiNeko

* GagBoobs: Wakaba's large bust is the subject of several chapters' worth of jokes.

* ACupAngst: Nao angsts over her small chest in comparison to [[BuxomIsBetter Wakaba's massive bust]].

* AlternateSelf: Nao has a dream where she is in a world where Shinta doesn't exist, and meets a melancholy version of herself with short hair. This short-haired Nao shows up in the final two arcs, having crossed the boundary between worlds as a [[OurGhostsAreDifferent Fragment of If]] to confess to Shinta. It turns out she is Nao's deceased sister, resurrected by Inaho for the purpose of fulfilling their wish.
* AngstySurvivingTwin: The long-haired Nao had a twin sister who died when she was a kitten and is buried at Inaho's temple. While she doesn't angst about it early on due to not remembering much from that time, she becomes melancholic about it in the last few chapters. It's strongly implied that the short-haired Nao is either the sister's ghost or from a universe where she lived but the long-haired Nao didn't.

** A more serious example is revealed in Chapter 91, where reveals she previously granted the wish of a pair of dying kittens to see the little boy who cared for them again. One kitten died before the wish can be fulfilled, resulting in a complex Schrodinger's cat situation where the boy - Shinta - has to choose which Nao is the kitten who died and which is the one who lived, resulting in one of them disappearing.

* DeadAllAlong: It's revealed that one of the two Naos died as a kitten and the other lived, but which it was isn't clear. Inaho's narration to Mikadzuki in Chapter 91 implies that the long-haired Nao - who wished to cuddle with Shinta forever - is the kitten who died and is buried behind the shrine, while the short-haired Nao - who wished to wait for Shinta forever - is the one that survived. To add to the confusion, UsefulNotes/SchrodingersCat is invoked, with Shinta unwittingly (at first) being forced to choose which of them was the twin who lived. In the end both of them live, so it ultimately doesn't matter which was which.

* {{Foreshadowing}}: Mikadzuki's knowledge of the Cat's Song and of the amnesia that ensues when a transforming cat forgets about the one they love, which foreshadows the revelation that he's a transforming cat himself.

* MacGuffin: The Naos' notebook ends up restoring Shinta's memory of them and returns them to existence.
* MagicMusic: The Cat's Song. Each transformed cat has a unique song in memory of the person they love, but can only awaken it through the heartbreak of forgetting about and regaining their memories of that person. The short-haired Nao and Miiko are shown singing theirs, Miyabi admits she has awakened hers, and it's strongly implied Mikadzuki has awakened his own as well. By the end of the manga, the long-haired Nao awakens her Cat's Song as well.

* {{Polyamory}}: In the end, Shinta refuses to choose between the Naos and ends up dating both of them.

** When Inaho grants the long-haired Nao's wish for Shinta to become a cat, everyones' memories of him as a human - except hers - are erased.
** Not wanting Shinta to be unhappy over having to choose between them, the Nao twins wish to disappear and have everyone's memory of them erased. Shinta's love for them restores his memory and he uses Inaho's magic box to bring them both back.

* SurpriseIncest: The long-haired Nao has a dream where she reunites with the short-haired Nao, who kisses her on the lips rationalizing that [[ScrewYourself it's OK since they're the same person]] and because Inaho said it doesn't count when two girls kiss. The short-haired Nao and long-haired Nao are later revealed to be twin sisters, though this doesn't bother them and they both end up dating Shinta at the same time.

* WhereAreTheyNowEpilogue: The final chapter is narrated by Miiko, who has become the leader of the cats after Mikadzuki retires and becomes Wakaba's pet. Miyabi leaves the town and becomes Shinta's grandfather's pet, while Shinta dates both of the Nao sisters.

* BalefulPolymorph: Inaho starts to turn Shinta into a fox as punishment for breaking off her tail as a child, though Nao requests she make him a cat instead. Shinta is later transformed into a cat when Inaho grants Nao's wish.

* CuteBruiser: Nao and Miyabi may look like 14 year-old girls, but they're a lot stronger than they look.
* DarkAndTroubledPast: When Mikadzuki confronts Inaho over the recent strange goings on, she tells him about Nao's backstory: A pair of newborn kittens were left in a box outside her shrine, and she waited for them to wish for food or warmth so she could use her divine powers to help them. When no wish came, Inaho found they were being looked after by a little boy. Just as she decided she was no longer needed and was about to go back to sleep, she felt the kittens wish to see the boy one last time, since the boy had been unable to come care for them and as a result they were dying. Before Inaho could grant that wish, she found that one kitten had already died and the other had been taken in by someone. With her powers weakened due to the little boy damaging one of the kitsune statues at her shrine while searching for the kittens, Inaho was only able to grant the dead kitten's wish -- creating the long-haired Nao and short-haired Nao in the process. With her power restored, she was able to create a Schrodinger's cat situation where Shinta would be unwittingly forced to choose which of them was the kitten that survived, and the other would disappear from existence.
