Name

 * Suisei's surname Hoshimachi「星街」can be divided as such.
 * The first kanji「星」can be read as "Hoshi/Sei" that means "star."
 * The second kanji「街」can be read as "Machi/Kai/Gai" which means "city."
 * So her surname can be translated as "City of stars."
 * Suisei occasionally romanizes her last name as "Hosimati," rather than Hoshimachi, which can be seen in her Twitter handle and various online usernames.

Miscellaneous

 * Considerably multi-talented as she is capable of drawing (her original image was drawn by herself), edit videos, sing, cook and is also a skilled gamer.
 * Suisei lives with her older sister, who is referred to by fans as "Anemachi." Anemachi is extremely attached to Suisei and used to be dependent on her for her cooking skills, but now has turned around and is often cooking for Suisei; Anemachi is very popular between Suisei's friends, specially Miko.
 * She is notably good at playing competitive Tetris.
 * The hashtag #星街すいせい3D (#HoshimachiSuisei3D) became a trending topic worldwide on Twitter when she debuted her 3D model on YouTube.
 * Her birthday and her debut date are the same.
 * A few years before considering being a VTuber, Suisei participated in several auditions for real-life idol agencies, but was rejected due to the "Jack of all trades, Master of none" trait, according to her. This led to her becoming a Virtual Idol, as a way of not giving up on her dream. However, she was already tired of trying by the beginning of 2019 as an indie Virtual Idol (since she worked in an izakaya [Japanese pub], and also had to do the editing of her own videos and other VTubers). Suisei almost gave up, but decided to make one last try. She went to COVER Corp to audition for hololive, but was also rejected, apparently for the same reason as the real-life agencies, since COVER Corp considered that she had many skills (speaking, singing, dancing, drawing and gaming) that could let to failing trying to do everything due to an overload of work. She claims that after receiving rejection e-mail, she e-mailed back seeking for a second chance and is open for suggestion. As a result, hololive replied back to have a second talk; then they told her that she could join, but on the condition of joining INoNaKa Music and focus on music. After more difficulty in INoNaKa Music mostly due to company policy that nearly broke Suisei's heart, she was finally transferred to hololive officially.
 * Suisei has won two editions of hololive Mario Kart 8 Deluxe Tournament.
 * She won the second edition of the tournament on 11 January 2021.
 * She also won the fourth edition of the tournament on 7 January 2023.
 * Suisei popularized the phrase "Hi, honey!" during a Duolingo English learning stream. Although Akai Haato was technically the first to use it, Suisei's endearing delivery of the line, coupled with her recent voice change, has since caused many other members of hololive to repeat it in a similar fashion.
 * Suisei featured "7days," the theme song for episodes 1-3 of the VR game "DYSCHRONIA: Chronos Alternate."
