Hakui Koyori is a female Japanese VTuber associated with Hololive. She debuted as part of the sixth generation under the name of "Secret Society holoX" alongside La+ Darknesss, Takane Lui, Sakamata Chloe, and Kazama Iroha. Koyori is the one in charge of R&D in Secret Society holoX and is known for her energetic and cheerful personality. While she may appear seiso initially, she has shown a more perverted side, occasionally dropping innuendos and displaying knowledge in NSFW fictions. With her insatiable thirst for knowledge, she often meddles in the affairs of her fellow members, both to help them and to observe their reactions. Despite being the self-proclaimed "brains of the operation," her areas of expertise are limited. Hakui Koyori's strengths include skill with tongue-twisters, good memory, skill with numbers and mental games, detective skill, typing, and voice impersonations.
