Biography:Clear Usui

From HandWiki

Template:Infobox social media personality Clear Usui (宇推くりあ, Usui Kuria) is a Japanese virtual YouTuber who commentates on rocket launches and promotes space programs.

Activity

Usui debuted as a "rocketry idol VTuber" on 10 October 2020. She said in interviews that she had been interested in space from a young age, admired the characters of Love Live!, and became a VTuber to pursue both interests. She mainly livestreams rocket launch watchalongs, as well as singing.[1][2]

In 2021, Usui won the Best Fashion Award on Nippon Television's Project V VTuber Awards 2021 for her self-designed outfit, which incorporates rocket motifs.[3]

Usui gained attention in February 2023 for her detailed explanation of the aborted first launch attempt of the first H3 test rocket, and in March 2023 for her call to support JAXA after the failed second launch attempt.[4][5] In July 2023, she was briefly interviewed by and provided footage to local media after livestreaming the explosion of an Epsilon S rocket engine during test firing.[5][6]

In 2025, Usui won a popularity contest on Sanrio's content creation platform Charaforio, and received a 3D character model and performance at Sanrio Virtual Festival 2026.[7][8] Her previous 3D model had become unusable in 2022 when the associated avatar software V-Katsu ended service.[1][9]

Usui has written articles for astronomical magazine Hoshinavi on lunar program HAKUTO-R and space telescope XRISM.[10][17][18] She has also interviewed people in the space industry such as Takafumi Horie.[19]

She was a sponsor of the first and second H3 test rockets, and of miniature Lunar rover SORA-Q.[19][20][21]
