Aster Arcadia

Who is Aster Arcadia?

Aster Arcadia is an English‑language male VTuber affiliated with NIJISANJI EN (ANYCOLOR Inc.). He debuted as part of the ILUNA wave in July 2022 and is presented in character as a Celestial One born from a supernova whose goal is to spread happiness across the universe.

Aster performed as a singer, streamer, and online personality whose content mixed music, gaming, and variety streams. His official fan mark and colors are represented by the symbols and palette often shown with his name.

Creator & studio

Aster Arcadia was produced under the NIJISANJI project operated by ANYCOLOR Inc. He debuted with the NIJISANJI EN ILUNA group in July 2022 and appeared across the project’s official channels and merchandise.

The character design and key illustrations are credited to illustrator Amaichi Esora (rain1e name in Japanese), who published the character artwork used in official introductions and promotional materials. His on‑screen model is presented in a Live2D style consistent with NIJISANJI EN production assets.

Visual Style and Aesthetics

Aster’s visual design centers on celestial and star motifs. He is commonly depicted with purple hair accented by lighter streaks, star‑shaped accessories, and a color palette that shifts between purple, blue, gold, and magenta.

His look often features a stage‑ready idol aesthetic: layered outfits that mix fantasy elements with contemporary fashion touches, distinctive star ornaments, and a playful, slightly theatrical presence in official art and thumbnails.

Content Type & Format

Aster created primarily prerecorded and live video content on YouTube, supplemented by social posts on X and occasional livestreams on other platforms. His output included full livestreams, short clips, edited music videos, and community posts.

Music and singing were a recurring focus of Aster’s channel: he released covers and participated in group music projects, and music videos and single releases featured as polished, edited content distinct from casual streams.

Beyond music, Aster’s content mixed gaming sessions, free talk and roleplay streams, ASMR and themed variety streams. His on‑screen tone blended upbeat charm and playful flirtation, which shaped how he interacted with viewers and fellow ILUNA members during live chat, clips, and collaborative videos.
