Higashino Hikaru: Higashi is his surname, and Hikaru is his given name. A mediocre cook, he transmigrates with nothing but a cleaver and a chef's knife, and has no choice but to work for some no-name gang in Yokohama, cooking meals to earn a living.
But only a few days after he starts, the gang is attacked by a rival organization. At the critical moment, Higashino Hikaru steps up!
He whirls a Chinese cleaver in one hand, and a five-clawed golden dragon leaps from its blade!
He swings a Western chef's knife in the other with fearsome force, sending a rainbow of light flying from its edge!
...Then a top enforcer sent by the rival organization kicks him a hundred miles away, leaving him dazed and barely able to tell himself from a machine.
When Higashino Hikaru wakes up, the guilt-ridden enforcer pays for an extended stay in his VIP hospital room, so he doesn't have to worry about food, clothing, or shelter for a while.
The aftershocks of the fight have badly damaged Higashino Hikaru's phone. All he can find on it are electronic recipes and cooking videos. Whenever he opens it, he hears the friendly call: "Kidnap all the chefs, and you'll make money as soon as you open a restaurant."
At the same time, he discovers that the treasured knives that came with him have developed serious problems!
An old man who claims to be a Special Grade Chef emerges from his beautiful cleaver. He is deeply unimpressed by Higashino Hikaru's dreadful cooking skills and would love to train him around the clock until he can cook dishes that glow.
His elegant chef's knife seems to let him communicate across worlds with a refined, rainbow-haired strongman who eats three hundred pounds of food a day. They can even trade specialties from their respective worlds through the knife.
What's more, Higashino Hikaru discovers that this world is far more complicated than he imagined. Superpowered individuals, espers, and sorcerers are everywhere, not to mention beings who surpass humanity!
Oh!
Higashino Hikaru grips the knife in his hand.
I understand now. It wasn't by chance that I came to this world. The world itself called me here!
I won't just become the king of cooking competitions in the surface world. I'll become the supreme chef of the hidden world, too!
These two knives are the first step toward conquering the world!
Higashino Hikaru bursts into a chuunibyou fantasy, flames blazing around him.
You can't blame him.
After all, before he came here, he was just an ordinary high school student.
And everyone knows high school students can save the world.
...Before Higashino Hikaru can announce his lofty ambitions, a nurse smacks him on the head and orders him to take his medicine.
