Mikoto Mikoshiba (御子柴 実琴 Mikoshiba Mikoto), also known as Mikorin (みこりん), is one of the heroes of the series. He is one of Umetarou Nozaki's assistants and the best friend/classmate of Yuu Kashima.


Mikoto is considered to be a handsome guy (by his peers) with red hair that is swept to the right side, red eyes and red studs on both of his pierced ears.

He wears two different outfits:

  • At school, he wears the standard Roman Academy uniform unbuttoned over an orange shirt.
  • According to his bio, when not in school, he likes to wear flashy clothes and follow fashion magazines.


Mikoto attracts the attention of many girls and he is admired by the males as well. However, in reality, he has a timid and 'tsundere' attitude. While outwardly he flirts with girls shamelessly and confidently, he cringes and becomes embarrassed at his own actions afterwards. Despite his own incompetence in romantic situations, he is perceptive when it comes to his friends' love lives. He can accurately infer when they are in need of assistance and is always willing to help.

It is discovered that his personality is actually the inspiration for Mamiko (Umetarou Nozaki's heroine character). While some characters figure this out and constantly make references to it, Mikoto seems to be completely oblivious.


Three years ago, Mikoto was unable to confidently speak to girls, so he started to 'study' by playing dating sims. Discovering that there were more to individual women than meets the eye, he decided to conquer them all! Thus, leading this pure boy into a world of dating sims and figurine collecting.


Mikoto has no skill when it comes to drawing people or inanimate objects. However, he is an expert at drawing flowers, effects and embellishments to bring out the charm in the characters. Besides art, Mikoto is also fluent in the language of flowers. He uses this information to pinpoint the exact flower needed to match the atmosphere of any scene in 'Let's Fall in Love'.


Umetarou Nozaki[]

Nozaki met Mikoshiba while observing people as reference for his manga. As they got closer, Mikoshiba became his first assistant. Mikoshiba and Nozaki are good friends, he would stay over at Nozaki's place for advice on his dating sim games, confides his about his otaku hobbies, and even keeps a part of his otaku collection in Nozaki's apartment closet. Mikoshiba is not aware that he is the model for Mamiko.

Chiyo Sakura[]


Mikoshiba is introduced to Sakura through Umetarou Nozaki. At first, Mikoshiba would act distant, but over time, he becomes comfortable around her and sees her as a little sister. They sometimes hang out during breaks, off-school hours and manga work. He is aware of her crush on Nozaki that he desperately and hopelessly tries to move it forward, only for Chiyo to confess her love to Nozaki at the firework festival and NOZAKI take it as a way of Chiyo saying how much she loves the fireworks. Despite his initial protest, Sakura calls him "Mikorin".

Yuu Kashima[]

Mikoshiba and Kashima have been in the same class since their first year in high school and became best friends after their constant one-sided-rivalry with each other. They have a good friendship, when allowed to invite a friend, they would usually invite each other. According to a Q&A with the author, the two pass the time with normal guy conversations and Kashima is not completely aware of Mikoshiba's otaku hobbies.

Masayuki Hori[]


Mikoshiba knows Hori as the Drama Club President who escorts Yuu Kashima to her club activities. Before meeting him in Nozaki's Apartment, they never talked to each other. Initially, he is not aware that Hori does the backgrounds for Nozaki's manga and finds his tendency to take photos odd until he finds out in Chapter 121.5 . He tends to be cautious regarding his relationship with Kashima, worrying about Kashima's well-being given the Hori's rather violent treatment of her, or possible jealousy given how much the two like each other. Hori noticed the resemblance between Mikoshiba and Mamiko when he helped in a play and has been pronouncing his name wrong, adding "Mami-" from Mamiko at the start ("Mamikoshiba"), but Mikoshiba is not aware of that.

Mayu Nozaki[]

Mikoshiba, as an elder, feels responsible for Mayu, often talking and watching over him, especially when Umetarou Nozaki isn't there. The two are on good terms and are often drawn together in promotional materials. Mikoshiba follows a blog titled 'MayuMayu' which features art by Mayu, under the assumption that is is run by a girl, and occasionally text each other. Due to the art style (that is based on his otaku collection) and cute, female facade, Mikoshiba had practically said MayuMayu is his type. As for saying MayuMayu is his type, technically Mayu is his ideal type, with Mikoshiba freaking out over one text from Mayu saying “i’m MayuMayu”. Mayu proclaiming Mikoto is his and Mikoto thinking of getting Mayu souvenirs when he went on a school trip (Vol. 10)

Hirotaka Wakamatsu[]

Mikoshiba is initially intimidated by Wakamatsu's "athlete" status, thinking that they would not get along because of the difference in interest. However, Wakamatsu admires him greatly as his senior, which calms his nerves. The two accidentally expose their position as assistants and start having schedules when they work together. Mikoshiba believes Wakamatsu is a good kid with a pure heart, but can't bring himself to reveal his otaku hobbies to him. Mikoshiba is aware of his crush on Lorelei and Lorelei's true identity but does not say anything because of how awkward the situation is, calling him a new breed of "tsundere".

Yuzuki Seo[]

Mikoshiba is not close with Seo, but he knows her to be a good friend of Kashima and Sakura. She first meets him falling off a tree on her way to school, and tends to call him "Ikemen" rather than his actual name. He finds her personality too coarse for him to get along with. He learns about her role as Lorelei through Sakura, but he finds the situation too awkward to reveal to Wakamatsu.
