Koikimo

Koikimo is a comedy, romance, and slice-of-life ONA produced by Nomad, based on the manga by もぐす. The story follows Ryou Amakusa, a suave adult professional who falls head over heels for high schooler Ichika Arima after a chance encounter—and wastes no time making his feelings embarrassingly clear. The age-gap dynamic and Ryou's shameless, over-the-top pursuit deliver a perfect blend of cringe-worthy comedy and heartfelt romance. Directed by Naomi Nakayama with series composition by Yuko Kakihara, the anime faithfully captures the original manga's irresistible charm. If you're a fan of bold romantic comedies with a twist, Koikimo is your next must-watch ONA.

Set in contemporary urban Japan, this romantic comedy follows Ryou Amakusa, an office worker with a rather carefree and flirtatious attitude toward relationships. His ordinary daily life takes an unexpected turn one rainy day when a high school girl he has never met before comes to his rescue at a train station. The girl's name is Ichika Arima. This chance encounter sparks something entirely new within Ryou, igniting an intense and overwhelming passion that he has never experienced before. What follows is a lopsided pursuit filled with over-the-top declarations and cringe-worthy advances from Ryou's side, met with sharp and blunt reactions from Ichika. The stark contrast between the two characters' personalities forms the comedic backbone of this story, making it a lighthearted yet relatable take on modern love and the awkwardness that often comes with it.
