Keiichiro Tsumugi

Keiichiro is passionate about seeing others smile through his cake creations, which he values above all.

He is so dedicated to his craft that he never considered quitting, even though the job leaves him perpetually exhausted.

His tendency to become absorbed in baking sometimes leads to him collapsing from fatigue before reaching the sofa upstairs.

Despite his intense focus, he cherishes moments of joy and relief when his work makes people happy.

Family

Keiichiro is the father of Rintaro and Sotaro Tsumugi.

He is married to Kyoko Tsumugi, who lightheartedly calls him a "cake otaku" due to his single-minded devotion to pastries.

With Rintaro Tsumugi

When Rintaro asks for help making a birthday cake for Kaoruko Waguri, Keiichiro goes all-in as a mentor.

He teaches Rintaro with a professional’s discipline, showing no hesitation in working him to the point of exhaustion.

Despite joking with Kyoko about being stern, Keiichiro becomes properly strict and supportive after learning of Rintaro’s wish to become a patissier.

He tells Rintaro that he should not work at the family shop straight after high school, emphasizing the importance of broader experience.

Keiichiro serves as both a passionate craftsman and a mentor, guiding those around him in both life and pastry.

Though strict in teaching, his caring nature and desire to see others grow shine through his actions.

Baking is more than a job for Keiichiro—it’s a way of life that brings fulfillment and fatigue in equal measure.

He frequently pushes himself to the edge, sometimes falling asleep on the stairs from exhaustion after long hours in the kitchen.

Keiichiro’s dedication to pastry is so consuming that he has never once thought of changing careers.

His teaching style balances professional rigor with heartfelt warmth, leaving a lasting impact on his family and all who visit Patisserie Plain.
