A character from [i][[Getsuyoubi no Tawawa]][/i] that parodies [[Yamamura Sadako]] from [i][[The Ring]][/i]. Her name comes from [[Himura Kiseki]]'s Twitter comments on the character.

Generally resembles Sadako, but with [[alternate breast size|much bigger breasts]] and apparently far less obsession with killing people, as she ceases to show such tendencies from her second appearance onward in favor of developing a possessive quasi-cohabitative relationship with the boy she's currently haunting.

According to [i]Getsuyoubi no Tawawa Sono VIII[/i], she was a popular child actress but "couldn't get a decent job" and got bullied at school after growing up due to her breast size. She died from accidentally falling into a well because of her heavy breasts during the filming of a low-budget [i]The Ring[/i] parody movie in 1998.

She collected many old game consoles and other electronic products from 1990s in the well like [[Super Famicom]], [[Game Boy]], [[Playstation 1]], [[Tamagotchi]] and Cassette boombox.

She has [[very long hair]], [[bangs]] that obscure her eyes, and wears a white [[robe]]. And as noted above, like other female characters in the series, she has [[large breasts]]. Recently, the author has stated she's the [[huge_breasts|largest]] of the current girls.
