Matsuri is a first-year student at Ohananomitsu Middle School and Aijou Rentarou's 27th girlfriend. She's best known for her loud, outgoing personality and gothic lolita style—basically, if there's a festival happening, she's already there. Her enthusiasm for festivals is genuinely unmatched; fans often note it's pretty much her entire personality, and honestly, that's part of her charm.
She's half Japanese and half British, which shows up mainly in her exaggerated British accent whenever she speaks. It's a bit much, but it fits her over-the-top energy perfectly.
Her name comes with some intentional wordplay. "Matsuri" combines the characters for "festival" and "plum," which is fitting given her obsession. "Dei," her surname, comes from an Edo period dialect particle that basically works like "desu" or "da"—it's a quirk baked into her name from the start. Plus, her birthday falls on August 15th, which is Obon Festival in Japan, so the festival connection goes deep.
