Since Shion has a liking towards teasing and playing pranks on others, especially Mion and Keiichi, she is often noted as the internet meme Luv or troll of the Higurashi series. Also, the "Shi" (詩, kanji for poetry) in "Shion" is also spelled the same as "shi" (四, kanji for four), so fans celebrate "Shii's Day" on April 1st, which is also April Fool's Day, as a homage to her name and unique personality.
