- Tsundere –

- Yandere –
refers to a character who starts out nice and sweet but eventually becomes dark and obsessive over the one they love.

- Deredere –
refers to a character who is completely kind, happy, and energetic. No matter what may happen, they quickly revert to their cheerful self.

- Kuudere –
refers to a character who is often cold, blunt, and cynical. They may seem very emotionless on the outside, but on the inside they’re very caring — at least when it comes to the ones they love.
- Himedere / Oujidere – refers to a character who wishes to be treated like royalty by the person they love, even if they aren’t royalty in actuality.
- Kamidere –
refers to a character with a god complex. They’re highly arrogant and proud, and aren’t afraid to speak their minds and show everyone how right they are.
