BEASTFALL is a high-stakes survival entertainment show where physically elite celebrities—known as the “Beasts”—compete in extreme muscle battles to claim victory. One fall means instant elimination in this intense, adrenaline-packed showdown.
Representing STARTO’s athletic pride—their very own Muscle Prince—Rinne Sugeta joins the fierce survival competition BEASTFALL on October 15th.
“I’m carrying my agency and all idols on my back,” he says. “I want to drop the ‘self-proclaimed’ title and prove I’m really No.1.”
For Rinne, strength has never just been about muscle — it’s about heart, persistence, and the quiet courage to keep moving forward. Fans have followed him through every step of his journey, from the emotional highs of SASUKE to the demanding All-Star Marathon, witnessing a performer who refuses to settle for less than his best.
In SASUKE 2024: The 42nd Tournament, which aired on December 25th, Rinne made his fifth appearance since 2020 — and his most emotional yet. Wearing the number 52, he faced the First Stage with determination burning in his eyes. After two years of heartbreak of not clearing the First Stage, he finally cleared it again, hitting the buzzer with just 2.88 seconds to spare. As he cried out, “Yes!” through tears, fans everywhere felt their hearts swell with pride. That moment, raw and radiant, captured everything that defines Rinne — his perseverance, his sincerity, and his unwavering drive to overcome.
Even as he later fell in the Second Stage’s Backstream, his spirit remained unshaken. From fellow SASUKE veterans like Snow Man’s Hikaru Iwamoto cheering him on, to fans comparing his form to the legendary Makoto Nagano, Rinne’s performance became more than competition — it became connection. It reminded everyone why they believe in him: because he represents the beauty of trying again, and again, and again.
That same spirit now carries him into BEASTFALL, the new survival competition where a single fall means elimination. Representing both STARTO and the idol world, Rinne steps forward with pride — not to prove that he’s flawless, but to prove that he never gives up.
His self-proclaimed best feature, his calves, once praised by professional athletes, are more than just muscle; they’re the foundation of his philosophy: “Try and you will succeed. Stick with something and you will succeed.”
In the 2024 interview on Tokyohive, Rinne spoke about his passion for training, his goal of earning a personal trainer license, and how the phrase “がんばりんね (Ganbarinne)” became both a motto and a message to his fans. It’s more than a catchphrase — it’s an invitation to believe in yourself, to take one more step, even when it’s hard.
And so, as he takes on this new challenge, Rinne isn’t just competing — he’s continuing a story that has inspired countless fans around the world. From the 42 flights of stairs at the agency to the BEASTFALL arena, his journey is proof that dreams don’t end when you stumble — they grow stronger every time you rise.

I’m Rinne Sugeta from B&ZAI. Nice to meet you.
It makes me really happy to be able to compete not just with athletic idols or comedians, but also with people who are truly out there competing on the world stage. I’ll be carrying my agency on my back—and representing idols—as I take on this challenge.
Our agency has plenty of people who are confident in their athletic abilities, but I’m here today as their representative. Right now, I’m still the “self-proclaimed” No.1. For now!
So this time, I want to win and drop that “self-proclaimed” part once and for all.
I want to prove it. I’ll definitely take first place today and go home as the champion.
Ganbarinne!
No matter the outcome, Rinne is showing off his hard work and determination, and one can only admire the mental and physical strength the young idol possesses. Being on the show itself is a feat in itself, and something worth noticing. He’s a clear winner in our hearts, no matter what!
As Rinne is no stranger to showing off his hard work and well-trained body, there’s plenty of material to admire on their official TikTok!
Rinne’s pure but passionate determination deserves to be admired and praised. While he’s exceptional at his usual idol-related activities, he shines the brightest in physical challenges like BEASTFALL and SASUKE – the proof of his physical activities and training showing off in the best light possible.
While most people struggle to carry toilet paper and groceries home, Rinne makes these shows look like it’s easy. Just like the callouses left on the palms of his hands from his intense workouts, Rinne is sure to leave a lasting impression on anyone who watches him challenge himself to new heights.
The sky’s the limit when it comes to Rinne and his potential. がんばりんね！
