Towa Honda is a blonde-haired, brown-eyed male freshman at Aokisora High School. His laid-back, cheerful, and outgoing personality makes him popular, yet he remains fiercely loyal. He serves as class representative alongside Mami Mihashi.

Naturally athletic, Towa contributes to the soccer club and volunteers enthusiastically for multiple events during the Sports Festival. His strained home life leads him to frequently sleep over at best friend Haruki Mishima's house without informing his mother, showcasing recurring communication issues and forgetfulness about responsibilities, often needing Haruki's reminders.

Towa develops a romantic interest in Mami Mihashi after discovering her secret love for shojo manga and cute things. Despite Mami initially avoiding him due to his perceived irresponsibility and talkative nature, he pursues her persistently. His approach involves physical affection like grabbing her hand or shoulder during conversations and openly expressing his feelings, which often embarrasses her. Their relationship progresses through shared activities, including partnering for a Sports Festival three-legged race where Towa creates a training regimen to support her.

He demonstrates protectiveness over Haruki's romantic involvement with Miharu Mashiki, actively investigating Nasa Sanagi upon seeing him interact familiarly with Miharu at a hospital. Towa frequently instigates interactions among friends, using teasing to provoke emotional honesty, particularly helping Haruki confront his feelings. He readily volunteers assistance, such as joining Haruki for unasked student council tasks.

As his relationship with Mami deepens, both face familial pressures: Towa struggles with his mother while Mami conceals their relationship due to her strict household. These concerns temporarily drive them apart, prompting Haruki and Miharu's intervention. Towa remains openly affectionate with close friends, often hugging Haruki when emotional and disregarding personal space boundaries non-romantically.

His defining trait is straightforwardness; he verbalizes thoughts without filter, regularly declaring his affection for Mami despite her discomfort, believing honesty facilitates change. This trait extends to encouraging friends to address feelings directly. Throughout cultural festivals and daily school life, Towa consistently supports peers emotionally while navigating his evolving relationship with Mami and familial obligations.
