Koharu Seto (瀬戸 小春 Seto Koharu) is a supporting character appearing in the Shigatsu wa Kimi no Uso series. She is the daughter of Hiroko Seto.


Koharu is generally a happy and cheerful child who adores her mother, Hiroko Seto. Koharu has been shown to be quite shy and hesitant around others when she first meets them[1], but eventually warms up to them and begins to consider them as her family, as seen when she drew a picture of Nagi Aiza playing the piano with Kousei Arima.[2] She shows affection towards those close to her, and compliments them - “You’re so good, Kousei ni-chan!”.[3]


Background Edit

Koharu was born to Hiroko Seto, sometime after Saki Arima died.

Shigatsu wa Kimi no UsoEdit

After Kousei Arima's first piano competition after two years, Koharu and Hiroko Seto go to Towa Hall, for a “nostalgic” reunion with Kousei. When her mother is concerned about Kousei (who hadn’t answered her recent phone calls), Koharu and Hiroko pay him a visit to check up on him, only to find that he had been asleep in his clothes from the day before. As he wakes up, Koharu exclaims, “Zombie? Zombie?!”. Hiroko forces Kousei to take a shower, attempting to take his clothes off for him, as Koharu covers her eyes in the process. Kousei offers her milk, but seeing as she hadn’t seen him for two years, she hid behind her mother’s legs in shyness.[4]


Koharu offers Kousei a candy apple

At a festival, Koharu purchases three red candy apples and offers one to Kousei, who misunderstood moment of stillness leads Koharu to cry, thinking that Kousei doesn’t like candy apples. He accepts a candy apple in the end, and Koharu cheers up immediately.[5]

Later, Kousei begins giving her piano lessons.[6]
