Chika Ueda is a character in the Persona 2 duology.
"A writer for Sevens' school paper, also known as Rumormonger Chikarin. She's scatterbrained but excels at digging up scoops."
Chika, or Rumormonger Chikarin as she calls herself, is, as the title implies, one of the several people in Sumaru who devotes herself to the flow of information through rumors. She is a first-year student of Seven Sisters High, and works with the school newspaper. She is a classmate of Tatsuya Suou and Lisa Silverman; she is usually found hanging out at the Peace Diner at Yumesaki District. Ghost stories seem to bother her a lot.
