Mika Takekawa is a character in Killer Is Dead. She is a 20-year-old Japanese woman who acts as Mondo Zappa's personal assistant. The two met each other at a 'certain event', after which they moved in with each other. She is skilled at cooking half-boiled eggs, Mondo's favourite food, and has a rather scatterbrained personality. Mika shares her name with Mika Kishi, the protagonist of Moonlight Syndrome.
