A highly dangerous youkai with the power to manipulate flowers, and reputed creator and original wielder of the Master Spark (which Marisa later "borrowed"). Hinted by Hieda no Akyuu to exhibit a rather polite facade, provided she or her flowers are not harmed. Once described by ZUN as "Youkai moe~", possibly meant as a pun given that the literal meaning of moe is "budding" and Yuuka controls flowers. Yuuka's place of residence is unknown in canon, but is generally assumed to be the Garden of the Sun, where she tends a massive field of sunflowers, and it is known she used to occupy the Dream World mansion Mugenkan with her then-retainer Elly. Frequently portrayed in fan works as the Ultimate Sadistic Creature (USC), as a bloodthirsty psychopath, or as tsundere. Usually some combination of the first two (or of all three). Alternately, she is often depicted as lonely due to this reputation or as very friendly to Team 9 and other children.
Noukarin (Farmer-Yuukarin): Originally a type of Yukkuri Shiteitte Ne, unusually depicted with a full body instead of just as a head. Now this word means Kazami Yuuka wearing a straw hat. Noukarin is frequently depicted with an acoustic guitar and/or with an almost impenetrable rural accent.
Bakerin (Bakery-Yuukarin): A recent variant of Kazami Yuuka who makes bread in her own bakery named "Bakery Kazami". A certain tweet caused this trend.
