Season 1

After his dream of becoming a charismatic hairdresser is shattered, Higurashi Ayumu (Nakajima Ayumu) ​​embarks on a journey of self-discovery, where he happens to come across Tsukishiro Barber Shop. He begs the owner, Tsukishiro Tsukasa (Kusakawa Takuya), to hire him, but it turns out that Tsukishiro has a secret life as a backroom hairdresser.

Higurashi (Nakajima Ayumu) ​​asks Tsukishiro (Kusakawa Takuya) to help his client, Miyo (Shida Kohaku), who is being attacked by the unscrupulous hairdresser Katsuragi (Watanabe Hide), but ends up working as a live-in employee with no way to pay the fee. One day, a client shows up.

A robber appears at Tsukishiro Barber Shop, and it turns out that the robber is the uncle of Fuma (Harada Konosuke), a high school student who happens to be passing by. Fearing they will be discovered, the two men flee. A few days later, a former basketball player visits the barber shop, and the two events are connected in an unexpected way.

After fighting with Tsukishiro (Kusakawa Takuya), Higurashi (Nakajima Ayumu) ​​runs out of the barber shop and witnesses suspicious masked men trying to attack Fuma (Harada Konosuke). Higurashi confronts the men and decides to take Fuma back to Tsukishiro Barber Shop.

Higurashi (Nakajima Ayumu) ​​is invited by a friend to a party at an entertainment agency, but what he witnesses there is a strange sight: the agency president and managers exerting psychological control over the talent.

Higurashi (Nakajima Ayumu) ​​and Tsukishiro (Kusakawa Takuya) thought they had solved the request, but the abnormalities at the agency had not improved at all. So, in order to get to the root of the evil, they decided to send Fuma (Harada Konosuke) to an audition at the agency.

Higurashi and Tsukishiro receive a request to remove a suspicious man using a wrestling ring without permission. However, they soon find themselves trapped inside a gym and forced into a bizarre confrontation with a man who suddenly pulls a gun from his mouth.

Higurashi and Tsukishiro are summoned to a café by Ushikubo. When they arrive, they discover an unlikely group gathered there—including Ushikubo, a hitman, a security guard, and a hacker. As a chaotic drinking party unfolds, the mysterious Shinnosuke finally makes his move.

Angry at Higurashi and Tsukishiro for sending messages to the girl he likes without permission, Fuma storms off. Determined to uncover the identity of the man who attacked them, he begins carrying out his own plan.

Tsukishiro attempts to infiltrate the Sasaki family to take revenge on Ushikubo, but his plan fails. In the aftermath, he uncovers a shocking truth about the past from Shinnosuke’s parents, Hiroki and Sanae.

Higurashi and Tsukishiro, having vowed to fight together, head to the final battleground alongside Riko and Nitta to confront the Sasaki family led by Shinnosuke, as they prepare for a decisive clash that will determine the outcome of their struggle.

The final battle reaches its climax as Higurashi and Tsukishiro face Shinnosuke in a direct confrontation; as the fierce back-and-forth fight pushes them to their limits, the outcome of the battle—and their fate—hangs in the balance.
