Gaku Kitada

Gaku is an 18-year-old male.

He is portrayed by Fumiya Takahashi in the live-action drama.

In the promotional video, his voice actors are Ryosuke Tomita and Daiki Yamashita.

Gaku is a driven and intelligent young man with a deep passion for mathematics from an early age.

After his dream of becoming a mathematician collapsed due to feeling the limits of his talent, he fell into a period of apathy.

With the encouragement and spark provided by Kai Asakura, he finds himself revitalized, showing creativity, wonder, and intensity in the kitchen.

He tends to get absorbed in his work, sometimes forgetting even his surroundings.

Gaku's personality sharply changes in the drama series when he becomes cold, aloof, and arrogant due to overwhelming loneliness.

Gaku hails from Yamanashi Prefecture.

He was a special scholarship student at the private Wells Academy High School.

After graduation, Gaku was accepted into the University of Tokyo, Faculty of Science, with nearly perfect scores, demonstrating his academic brilliance.

He gives up on university to pursue cooking, inspired by Kai Asakura.

Gaku's mother passed away, and his father runs a bicycle shop.

Gaku is an exceptional cook, blending his mathematical background into culinary innovation.

His unique, logic-based approach generates awe-inspiring recipes that surprise everyone around him.

He adapts quickly, inventing new dishes and techniques by applying mathematical principles.

Kai Asakura becomes Gaku's mentor and a significant figure in his life.

After meeting at the school cafeteria where Gaku worked part-time, Kai introduces him to the world of professional cooking.

Gaku lives with Kai in Tokyo, thanks to Kai's generosity, and learns directly under him at Restaurant K.

His late mother and his bicycle shop-owner father influenced his grounded side.

Ayu Uomi cared about Gaku since their high school days, adding a layer of emotional complexity in his journey.

Gaku’s mathematical viewpoint gives him a unique edge in cooking competitions and recipe development.

Despite being able to enter the University of Tokyo at any time, he chooses cooking out of pure impulsive passion.

In the drama, Gaku eventually becomes the owner-chef of Restaurant K, succeeding Kai Asakura.

After his personality shift, he loses the trust of his staff and customers, leading to the downfall of the restaurant’s reputation.

“In my excitement, I forgot this was a terrifying stage. I was having so much fun…!”

“To be honest, I could get into the University of Tokyo anytime I wanted. But this impulse—right now, right here—is unstoppable!!”

Manga

Gaku Kitada, once a math prodigy, loses faith in his mathematical abilities and abandons his dream of becoming a mathematician.

While working part-time in his school cafeteria, he meets Kai Asakura, a genius chef, whose influence helps Gaku rediscover his sense of challenge and creative joy through cooking.

He chooses to forgo his nearly perfect entrance to the University of Tokyo and instead follows Kai into the high-pressure world of restaurant kitchens.

Using his analytical mind, Gaku astounds his colleagues with mathematically inspired recipes, quickly rising in the culinary world.

Through loss, friendship, and rivalries, Gaku transforms from a lost student into a passionate chef.

Drama

The live-action drama closely follows the manga’s story, but introduces a one-year time jump between episodes.

Gaku is shown in the future as the owner-chef of Restaurant K, having taken over after Kai leaves the culinary world for personal reasons.

With Kai and Ayu Uomi’s departure, Gaku is left in deep loneliness, believing that pursuing the peak of cuisine means accepting solitude.

Shocked after Restaurant K is downgraded from two Michelin stars to one, Gaku’s personality becomes harsh and arrogant.

He alienates both colleagues and customers by focusing solely on the quality of his cooking, neglecting communication and empathy.

Ultimately, his actions cause all employees and the restaurant's clientele to abandon him, leading to the decline of Restaurant K.
