Cashero: Release Date, Cast, Plot—Everything You Need Before It Premieres

Netflix is closing out 2025 with a very Korean spin on superheroes. Cashero takes the classic what-if-I-got-powers setup and turns it into something both funny and painfully relatable: your strength literally depends on how much cash you have on you. Yes, heroism gets itemized.

When and where to watch

Cashero premieres globally on Netflix on December 26, 2025. All episodes drop at once, and the first season is reportedly eight episodes, so it is a clean holiday binge.

You will need an active Netflix subscription. Pricing varies by region; in the US, current monthly plans are $7.99 for Standard with ads, $17.99 for the ad-free Standard plan, and $24.99 for Premium. Mark your calendar for Boxing Day 2025.

The hook

Based on the Kakao webtoon by Team Befar, the series follows Kang Sang-woong (played by Lee Jun-ho), a regular civil servant whose modest dream is just to buy a home. Then he wakes up with powers that scale with the money in his pocket. Every punch costs him.

Every time he throws a punch, his bank balance drops.

That cash-to-muscle exchange rate forces Sang-woong and his longtime girlfriend/fiancée Kim Min-sook to do the math on what saving the day actually costs. It is a funny idea, but it is also very pointed about class, sacrifice, and that nagging feeling you can never quite afford the life you want.

The world (and its weird power rules)

Sang-woong is not the only one with an unorthodox power source. He gets pulled into a hidden scene where a lawyer, Byeon Ho-in, heads up something called the Korean Coalition of Superheroes. Ho-in’s own abilities only kick in when he drinks, and yes, he is the self-appointed chief. Together with Bang Eun-mi, a telekinetic who literally powers up on calories (pastries and bread are her thing), they go after a group known as the Criminal Association, which hunts down people with powers. It is action, romance, and satire in one package, with plenty of heightened, webtoon-style absurdity baked in.

Quick name note: you might see the lead’s name romanized as Kang Sang-ung in some official materials. Same character, same guy.

Cast and who they play

• Lee Jun-ho as Kang Sang-woong: A low-key civil servant whose physical strength scales with the amount of cash he is carrying.
• Kim Hye-jun as Kim Min-sook: Sang-woong’s longtime girlfriend and fiancée, a pragmatic numbers whiz who thinks his powers are inefficient but backs him anyway.
• Kim Hyang-gi as Bang Eun-mi: A young woman with telekinesis fueled by her caloric intake, especially pastries and bread.
• Kim Byung-chul as Byeon Ho-in: A lawyer whose powers activate when he drinks; he has made himself the head of an organization for people with superpowers (the Korean Coalition of Superheroes).
• Kang Han-na as Joanna: The daughter of a wealthy chaebol family.
• Lee Chae-min as Jonathan: Joanna’s younger brother, also from a chaebol family.

Who is making it

Director: Lee Chang-min. Writers: Lee Jane and Jeon Chan-ho. Produced by SLL and Drama House Studio, with Netflix distributing.

Production timeline

Filming kicked off in mid-February 2024 and wrapped five months later in July 2024. It has been in post-production since then to line up for the December 2025 launch.

Why it might be worth your time

Cashero is not trying to be a pure power fantasy. The show is set up to poke at economic inequality, the cost of doing the right thing, and the everyday pressure to make the numbers work. Also, the power mechanics are delightfully odd: cash-backed punches, booze-activated skills, and telekinesis powered by pastry. If you like your superhero stories with humor, heart, and a very human spreadsheet running under the action, this looks like a fun one to end the year with.

Watching or skipping? I am in just to see how many cronuts it takes to move a car.
