About
Sithle (シスル) is a Tokyo‑based Japanese cosplayer, costume designer, and variety‑show host whose vibrant handmade outfits and upbeat personality have drawn more than 560k followers across X, Instagram, and other platforms. Her self‑sewn costumes range from classic anime heroines to completely original characters, each photographed with a careful eye for lighting, fabric drape, and color. In January 2023, she fronted her own late‑night TV special, Sithle no Mira Kosu! on Nagoya Television (Me‑Tele), stepping into the role of on‑air MC while guiding guests through the craft of dressing up for the camera. The station later immortalized her “Year of the Rabbit” outfit as a 3‑D NFT, underscoring her crossover from convention favorite to mainstream media personality.
Before Fame
Born on January 21, 1996 (the date fans celebrate each year), Sithle kept most early details private but occasionally dropped clues on social media. A 2016 post about battling an “endless” graduation thesis shows she was still a university senior when she started sewing cosplay looks and attending summer Comiket that same year. After college, she signed with specialist talent agency 12COMPANY, juggling a full‑time office job by day and costume work at night; she has since left the roster to operate independently. Gaming remained her relaxation outlet—she often tweets about late‑night sessions and calls herself a long‑time fan of VTuber Sakura Miko.
Trivia
- Height: 161 cm, noticeably taller than the average Japanese woman, which gives extra presence in platform heels and elaborate wigs.
- DIY Ethos: Every major outfit is patterned, cut, and stitched by her, a skill that impressed Me‑Tele producers enough to dedicate a segment to her tailoring process.
- Commercial Work: In 2022, she appeared as fencing master Tsukahara Bokuden in the national TV commercial for the mobile RPG Houchi Shoujo, sharing screen time with actress Miyo Imada.
- Tech Firsts: Her 3‑D capture session used 115 cameras arranged in a full circle, producing a digital model that fans can display in AR—one of the earliest NFT tie‑ins for a Japanese cosplayer.
- Nickname: Friends on her private account call her “Sis‑nee,” a playful nod to the big‑sister energy she brings to photo shoots.
Family Life
Sithle keeps relatives out of the spotlight—no names or photos of parents or siblings have surfaced, and even her real name is undisclosed. What fans do know is that she lives on her own and refers to herself as a hardworking “corporate drone” who races from the office to the sewing machine most evenings. Support comes mainly from an online “found family” of followers who fund photo books on BOOTH or subscribe to her FANBOX for behind‑the‑scenes videos.
