To be added.
Ringo is eccentric and completely obsessed with curry. After trying it just once she left Ishana and dedicated her life to learning about curry. She will ramble on about curry to her junior Touya. Additionally, she has developed a strange opinion on "curry mannerisms," judging a man's enjoyment and etiquette based simply on the state he left his plate in.

She believes that life is all about learning things for oneself and hates things like TOi that take the work out of it.
