Voice of [[Kirisame Marisa]] in the original [[cookie_(touhou)|Cookie☆]]. Distinguishable by having her [[side braid]] on her right side of her head with a [[pink bow|pink]] [[hair bow|bow]], [[yellow eyes]], and her [[red-framed eyewear|red]] [[glasses]]. Also called Marina (her real name). Essentially the main character of Cookie, she was the one to recruit other members like [[Reu (cookie)|]] and [[Yamin (cookie)|]], the first criticized for her acting, and the first to expose [[Hazuna Rio]] causing the ensuing drama. Left the internet in 2011, but still in contact with Reu.

Usually appears as the main character in MADs due to the large amount of material she recorded. Almost all Marisas are called UDKs in reference to her, partially because her disappearance meant that the others had to live up to her. 

She spawned numerous running jokes:
* "Aaaaaaaaaah, wasureteta!" (Aaaaaaaaaah, I forgot!): Her line when she realized to forgot to reciprocate Alice's gift for Valentine's day.
* [[Van Houten]] cocoa: What she says makes Alice's brownies good.
* Tororo [[soba]] press conference: Her breakdown on a livestream when she was ranting about malicious comments sounded like she was slurping noodles.
* Starry Sky: A poem she wrote. See post #4488363
* Art college ball: A painting she made when applying to art school. Usually appears in the background of other images.

* Assassin UDK: Her [[black hoodie|black]] and [[white hoodie|white]] [[striped hoodie]] she wore during a stream
* Comiket UDK: A possible photo of her as [[Usami Renko]] at Comiket. Whether or not it is actually her is unknown.
* Iwana / Charfish: A soramimi pun during one of her livestreams.
