Kokorowa is a high-ranking goddess residing in the Lofty Realm; her overall demeanour is calm and collected in direct contrast to her best friend Sakuna; Kokorowa is both literally and metaphorically the blue to Sakuna's red. She has worked hard to reach where she is as a high-ranking goddess despite her low birth, and is keen to gain the favour of Lady Kamuhitsuki.
As an inventor goddess, one of Kokorowa's well-known inventions are the automatons standing guard over the Mihashira Capital.
- Kokorowa writes books under the author pseudonym Koushi Oborozuki, AKA Sakuna's favourite author - though she does not know this is Kokorowa.
- Kokorowa's name consists of "Kokoro", meaning "heart/mind" to convey her bright nature, and "wa" (wheel) as she is the goddess of tools and invention.
- She is based on Omoikane from Japanese mythology.
- Kokorowa was designed to contrast Sakuna - i.e. balanced, looks smart, and wears makeup beautifully
