Keisuke Suga, born into a distinguished political dynasty, escapes the shadow of his accomplished brother by fleeing his hometown as a teenager. In Tokyo, he marries Asuka Mamiya, co-founding K&A Planning, a publishing venture bearing their initials. Their daughter Moka’s 2016 birth brings fleeting stability until Asuka’s accidental death around 2019 spirals Keisuke into alcoholism, costing him custody of Moka due to his neglect exacerbating her asthma. Grief-stricken yet determined, he resolves to reclaim paternal rights while battling self-destructive habits.
A pragmatic entrepreneur, Keisuke monetizes urban legends despite scoffing at the supernatural. His disheveled exterior—tall, lean frame, untamed gray-streaked hair, and perpetually relaxed posture—masks a keen intuition and strategic mind. Though he deflects earnest conversation with humor and evasiveness, glimpses of empathy surface in his mentorship of Hodaka Morishima, a teenager he rescues during a storm in 2021. Employing Hodaka at K&A Planning, Keisuke offers shelter and guidance but prioritizes self-preservation, cutting ties to avoid police interference in his custody fight.
This calculated detachment fractures when Hodaka’s desperation to save Hina Amano, a girl with weather-altering abilities, compels Keisuke to aid their escape from authorities—a pivotal act of courage overriding his instinct for survival. Post-2021, he rebuilds K&A Planning into a respected enterprise by 2024, gradually mending his relationship with Moka through rare outdoor visits facilitated by Hina’s power. His once-cluttered office, a relic of grief, undergoes symbolic renewal after a deliberate flood washes away debris, mirroring his emotional reckoning.
Privately sentimental, Keisuke preserves a family photo of Asuka and Moka in his workspace, a silent testament to enduring bonds. Flawed yet resilient, he navigates redemption by supporting Hodaka’s reunion with Hina while reconciling past failures with fragile hope, embodying the tension between self-interest and hard-won compassion.
