Mikorin is a student at Roman Academy, attending the same year as Nozaki and Kashima. He has been friends with Nozaki for some time and occasionally visits his home to help with manga production. Despite his flashy behavior, Mikorin is not very popular with girls mainly because his charm vanishes the moment someone takes him seriously. He tends to say flirtatious lines instinctively, only to immediately panic and hide afterward.

When Nozaki observes Mikorin’s complex personality, he uses him as the template for Mamiko, the heroine of his manga Let’s Fall in Love. Mikorin is unaware of this at first but becomes horrified when he finds out. Still, he continues to help with the manga and becomes an essential part of the chaotic cast surrounding Nozaki’s creative world.

Mikorin is a slim but athletic teenage boy with short, spiky red hair and crimson eyes, often described as attractive by his peers. He wears the Roman Academy male uniform a white shirt, gray blazer, dark pants, and a loosened red tie. He’s typically seen with a confident pose, though his expressions quickly shift to shy or panicked when flustered.

His overall aesthetic gives off a “ladies’ man” vibe, which contrasts hilariously with his actual lack of composure in real romantic situations. His body language is often exaggerated, especially when he’s trying (and failing) to act cool.

Mikorin is a walking contradiction: he acts like a flirt, throwing out bold lines to girls, but immediately becomes nervous and self-critical afterward. In truth, he’s incredibly sensitive, introverted, and emotionally vulnerable. He spends hours overthinking minor social interactions, and despite being surrounded by people who admire his looks and energy, he struggles with self-confidence.

He enjoys video games and figurines, particularly those featuring cute female characters, which further cements his tsundere-like personality a cool surface hiding a soft, geeky interior. Mikorin is also deeply caring, often offering genuine compliments and emotional support to his friends, even if he tries to play it off afterward.

• The Flirt Who Can’t Handle Flirting
  Mikorin frequently attempts to charm girls with cheesy lines, only to blush and retreat in embarrassment when they respond. These moments are a consistent source of comedy, with his over-the-top bravado being immediately undercut by his shy reactions.

• Assistant to Nozaki
  Mikorin helps Nozaki with screen tones and character design, and he is also unknowingly the model for Nozaki’s manga heroine, Mamiko. His tsundere behavior, emotional vulnerability, and sudden shifts between bravado and awkwardness provide perfect inspiration for the emotional beats of a shōjo manga character.

• Unexpected Depth
  Though comic relief is his primary role, Mikorin occasionally shows moments of genuine insight and maturity. Whether he’s consoling friends, recognizing his flaws, or working hard on a shared task, Mikorin proves that he’s more than just a pretty face with a catchphrase. His duality as both a joke character and someone with emotional depth adds richness to the series.
