Natsuiro Matsuri夏色まつり

hololive 1st Generation VTuber, singer, and entertainer whose official character premise is a novice school cheerleader.

Natsuiro Matsuri (夏色まつり) is a hololive production 1st Generation VTuber whose character premise is a cheerful rookie on her school’s cheerleading team. Festival-loving and openly affectionate in her official introduction, she brings that energy to singing, gaming, and playful exchanges with viewers. She debuted on June 1, 2018, calls her fans Matsurisu, and dreams of becoming a top idol and voice actress.

Biography

A cheerleader with a festival spirit

Matsuri’s official character introduction places her as a rookie on a school cheerleading team. She loves festivals, events, and making friends; the group spirit of a celebration fits both her name and her signature “Wasshoi!” greeting. The school setting belongs to her VTuber character premise rather than to the private biography of the person behind the avatar.

Joining hololive 1st Generation

Her official debut-stream date is June 1, 2018. hololive identifies her as a member of its 1st Generation, a designation that situates her among the company’s early VTuber talents. Her cheerful “Wasshoi!” introduction and festival motif make her performance identity immediately recognizable.

Streams and creative ambitions

Matsuri’s official talent page emphasizes singing and gaming streams enjoyed with her viewers. It lists FPS games and singing as hobbies, flexibility and changing voices as skills, and an ambition to excel as both an idol and a voice actress. She also openly presents herself as a VTuber fan, making enthusiasm for the medium part of her public persona.

An expanding music catalog

“HiHi High Tension!” was released on July 23, 2021. hololive identifies it as Matsuri’s first original song and says it was initially unveiled at the end of her birthday concert. This marked a documented step from her performance-focused streams into officially released original music.

Her album “Chasing the Dream ~After School Spotlight~” was released on February 25, 2026, with a 14-track listing on hololive’s official music page. Its selection includes “HiHi High Tension!,” “ENDLESS FES,” and “LOVE LETTER,” showing songs from different phases of her music releases grouped into one album.

Performances and releases through November 2026

In May 2025, hololive announced Matsuri and fellow 1st Generation member Akai Haato as special guests for the New York date of its “hololive STAGE World Tour’25 -Synchronize!-.” This is a verified announcement of participation, not independent confirmation of every aspect of the eventual live show.

The official catalog also lists Matsuri’s single “Senshu Sensation,” released November 2, 2026. Her career is ongoing; unlike a completed fictional narrative, her public activity has no fixed canonical ending to recount.

Personality and Motivations

Her official introduction stresses energy, sociability, and affection: Matsuri loves the collective excitement of festivals, performances, and games. Her greeting is deliberately exuberant, and her public message suggests an entertainer determined to show fans her own version of an idol rather than follow a single prescribed image.

Matsuri plays with a cheeky contrast between the “purity” label in her greeting and the mischievous side acknowledged in her own official message. That tension is part of the presented persona; it should not be treated as evidence about the private individual behind the avatar.

Her ambition is direct: to become a top idol and voice actress. Singing, doing voices, and performing for an audience give that dream different creative outlets. Her official message adds a characteristically stubborn note: she wants to become the best idol she can be in her own way.

Appearance

In her recognizable original official design, Matsuri has light taupe-brown hair with uneven bangs, a prominent curved strand rising from the top of her head, and a side ponytail fastened by a dark ribbon with vivid green accents and a small pale mascot-like ornament. Her eyes are bright blue-green. These details are visible in hololive’s official character images.

Her cheerleader-inspired outfit is built around orange, white, black, and lime green: a cropped orange short-sleeved top with a broad white sailor-style neckline, a dark front panel, and a bright green neck ribbon, paired with a short white pleated skirt. Official full-body illustrations also show dark legwear and white lace-up boots. Alternate costumes exist, so this description refers specifically to the original featured design.

Interesting facts

Her fan name, Matsurisu, is also represented by squirrels; the official profile explains that “risu” means “squirrel” in Japanese.

The pun connects the name of her audience to a recognizable community mascot rather than treating it as an arbitrary nickname.

Hololive’s official profile uses #夏まつch for streams and #祭絵 for fan art.

The two distinct tags help separate broadcast discussion from artwork made by fans.

“HiHi High Tension!” was first revealed at the end of Matsuri’s birthday concert before its July 2021 release.

Its reveal tied her debut original song to a live celebration, not just to a routine music listing.

Hololive’s official Matsuri profile groups “Ebifrion,” “loot boxes,” and “donuts” under the same catchphrases heading.

Those unusually varied terms capture the stream-culture references recorded in her official persona, beyond the standard debut and birthday facts.
