I was not a dog. I was not a cat. I was nobody. Until someone gave me a name. RepBilly!

✨ BIG NEWS FROM REPBILLY ✨ REPBILLY has officially made his debut on Showrunner. Showrunner is an AI entertainment platform created by the Emmy-winning team at Fable, backed by Amazon, and described by founder Edward Saatchi as the Netflix of AI. And I still can’t quite believe it. REPBILLY is already ranked #9 in the Top 10 Watched. ✨ REPBILLY is a mysterious little creature traveling the world with one question. 「Who am I?」 Along the way, he carries people’s dreams on his back, crossing towns, mountains and valleys, meeting people and quietly becoming part of their stories. There is also a special magic in REPBILLY’s world. 「When REPBILLY carries a dream, that dream is touched by the magic to come true.」 Until just a few months ago, I had never used AI at all. Then circumstances forced me to stop moving the way I normally did. So I became completely absorbed in learning AI, and I began bringing life to REPBILLY, a character and hand-drawn comic I originally created ten years ago. A character that had lived on paper for ten years suddenly began to walk, run, speak and travel across the world. That experience changed everything for me. And now I want REPBILLY to become an opportunity for someone else too. If you have ever thought, 「I want to try AI.」 「I’m curious, but I don’t know where to begin.」 I truly believe REPBILLY on Showrunner can be one of the most wonderful and enjoyable ways to take that first step. You don’t have to be an animator. You don’t have to be a filmmaker. Just imagine something. Now, on Showrunner, you can enter REPBILLY’s world and create your own scenes with him. Send REPBILLY to someone you love. Let him carry your dream. Let him run across the world to meet someone special. Let him deliver a wish to someone far away. Create a little film as a gift. Make someone smile. Move someone’s heart. Turn something that existed only in your imagination into a story you can actually share. Send it privately to someone special. Share it on X or social media. Create something for your family, your friends, or someone you love. Create your own world with REPBILLY and please show me what you create. It honestly feels like a dream. My deepest thanks to Edward Saatchi, who discovered REPBILLY, and to the entire Fable and Showrunner team for opening this incredible new world to him. REPBILLY has always carried people’s dreams. Now he can carry yours too. And when REPBILLY carries your dream, the magic begins. 「REPBILLY will make your dream come true.」 If REPBILLY could carry one dream for you, what would you ask him to deliver? Watch, create and play with REPBILLY on Showrunner showrunnerstudio.com/shows/r… @fableshowrunner #REPBILLY #Showrunner #Fable #Amazon #Emmy #NetflixOfAI #Seedance #AIAnimation #AIStorytelling #AIEntertainment #Animation #CharacterIP #Worldbuilding

What if I’m actually a pig? REPBILLY was searching for who he really was. The little pig was frightened of something. REPBILLY placed the tiny pig—who had barely seen the world—on his back and started running. What would you do if you were REPBILLY?

REPBILLY Episode 30 “AM I A PIG?” – Deep Analysis Summary This is not just a cute short film. On the surface, it’s pure fluff: a soft, round creature named REPBILLY with a star tail, and a tiny pink pig, running through a dreamy pastel world. But underneath that cuteness lies something quiet and heavy about life and identity. REPBILLY is searching for who he really is, wondering, “What if I’m actually a pig?” The little pig, on the other hand, has almost accepted that his fate is to be eaten someday. Both of them are trapped by the question of “what am I, and what is my destiny?” when they meet. Then REPBILLY puts the frightened pig on his back and starts running. That simple act of carrying him begins to shake both of their fates at once. And while they’re running, the little pig suddenly shouts from REPBILLY’s back: “I want to live!” This is the core of the whole piece. It’s not just gratitude for being saved. It’s the exact moment the pig truly believes, for the first time, that another future might be possible. The fact that the cry comes while they’re moving, wind rushing past, makes it feel raw and alive. REPBILLY still doesn’t know who he is, yet he chooses to protect the fragile life in front of him. Before finding his own identity, he decides how he wants to live. That quiet choice hits hard. At the end, the pig says something like, “If I ever meet someone like you, I’ll make sure to tell you.” The one who was saved now carries the possibility of helping someone else someday. Kindness begins to chain. It has the same DNA as Chiikawa: extremely cute on the outside, but with a gentle melancholy and depth underneath. Most comments are just “so cute,” which makes sense — the design is magnetic. But for those who pause, the weight of that single cry, “I want to live,” lands fully. The film strips away almost all explanation and trusts one moment — a shout from the back — to carry everything. That restraint and clarity of feeling is what makes it special.

A flower no one chose. A little creature everyone avoided. And one woman who thought she would never receive flowers from him again. Sometimes, what is overlooked is simply waiting for the person who needs it most.

In July 2016, I drew REPBILLY for the very first time. It all started as a simple doodle. Over the years, I refined and shaped the character into the REPBILLY you see today. REPBILLY is a mysterious creature—neither a dog nor a cat.🐾

Thank you so much for always watching REPBILLY. To be honest, X used to feel like a scary place to me. Everyone is kind, yet on X, people sometimes become someone frightening. Words can become knives, and it’s painful to watch. That’s why I decided to plant the seeds of kindness here. For more than 10 years, I’ve carried a story in my heart. It’s about REPBILLY—a mysterious little creature that is neither a dog nor a cat. I drew REPBILLY over and over again in my sketchbooks until the character finally came to life. Back then, creating an animation felt impossible. I was overwhelmed by my daily work, so REPBILLY continued to live only inside my imagination. Then one day, an accident changed everything. I broke three bones in my leg. The pain was so intense that I could barely breathe, and I became bedridden. I was forced to stop working. That was when I first wondered, “Could AI help me bring REPBILLY to life?” So I started experimenting. I failed countless times. Lying in bed, my mind never stopped working. The entire world of REPBILLY already existed perfectly in my head. Every tiny difference felt wrong, so I spent day after day guiding AI closer and closer to the vision I had imagined. That’s why it makes me a little sad when people simply dismiss my work by saying, “It’s just AI.” To me, AI isn’t creating the story. It’s like working alongside countless animators to bring a world that has lived inside me for years into reality. Today, I feel that REPBILLY is slowly helping kindness spread, little by little. Thank you for being part of this journey. I hope you’ll continue to watch over REPBILLY. I just wanted to share a little piece of my heart today.

REPBILLY is certainly different from everyone else. His lip-shaped fur pattern is unique. I’ve never seen a face like his before. What do you think?

No one knows what REPBILLY really is. Believing it was the only one of its kind… REPBILLY suddenly saw another. Pink eyes. Just for a moment. Was it another lonely soul… or only an illusion?
