Merry-san

Mary-san who calls you on the phone, telling you she's nearby...nothing but a prank call, right? Witness the cute and charming life she lives!

This is based on the Japanese urban legend Mary-san. If it makes no sense at all to you, see https://www.kowabana.net/2018/06/09/mary-san/ and it will be a lot more comprehensible, while still being cute.
