Dazzling lights, elaborate choreography, and thousands of fans cheering enthusiastically under one roof in Tokyo, Japan. The scene resembles a typical pop star concert, but one detail changes everything: the on-screen superstar has never actually set foot on a stage; she is simply “not human.”
She is Kizuna AI, the two-dimensional anime character who redefined stardom in the digital age as a pioneer of the VTuber phenomenon. Despite a brief hiatus that began in 2022, AI returned to the forefront in February 2025, cementing her status as a global phenomenon.
Behind the digital mask: Humans telling the story. Behind the cute anime face stands an army of creators. In a state-of-the-art studio in Shinjuku, 25-year-old dancer Amika wears a special motion-capture suit, surrounded by 28 cameras that meticulously record her every gesture and translate it into the virtual character.
“VTubers have opened up new horizons for dancers,” says Araki, Kizuna Ai’s veteran choreographer. “Before, the ambition was to dance behind the stars, but now many are joining us to become the ‘engine’ of these characters. The beauty here is that age and physical appearance don’t matter; what matters is the spirit and the performance.”
From a college idea to a “connections” empire: The idea for Kizuna Ai was born from the ambition of two college students, Takeshi Osaka and Junji Matsuda. They chose the name “Kizuna” (meaning “connections” in Japanese) to reflect the program’s desire to connect with people, while the word “Ai” carries a duality; It symbolizes artificial intelligence, and at the same time, it sounds like the Japanese word for “love.”
“We designed the character to be appealing in a Japanese anime style without being over the top, to ensure its acceptance by a wider audience,” explains Osaka, CEO of Activ8. While Western audiences readily embraced her as a living, breathing fictional character, it took Japanese audiences some time to immerse themselves in this phenomenon, which has become part of the “oshikatsu” culture, where fans spend vast sums of money supporting their favorite icons.
Fans… Love Beyond Screens
Ai’s popularity extends far beyond Japan, reaching over 3 million YouTube subscribers. Joe Chaohing, 26, traveled from China to Tokyo just to see her comeback show last September. With tears in his eyes, he said, “I was so sad during her hiatus. Today, I wore the outfit Ai-chan loves… I’m so happy to be here.”
The Real Challenge of Artificial Intelligence
Today, Kizuna Ai faces competition not only from other VTubers but also from AI-generated content. However, Osaka remains optimistic: “No matter how advanced technology becomes, people will always be drawn to the human element behind a character. We are always looking for traces of human effort and struggle in creation, and that’s something a machine alone cannot provide.”
With ambitions reaching for the Coachella World Music Festival and anticipated international collaborations, Kizuna Ai proves that the future may not be entirely human, but it will undoubtedly remain vibrant with human emotion.
