Differentiate between the tsundere, yandere, kuudere and dandere personalities that are usually presented in Japanese animations.
There is no clear definition of these terms, as they refer to specific types of personality in anime or manga (Japanese animation). Some fans use them interchangeably with similar character traits found in other media like video games, while others may have their own definitions for each one based on their experiences with certain characters or storylines.

In general, a tsundere (or tsurune) personality is characterized by strong emotions towards someone who does not return those feelings, but gradually warms up to you over time. The opposite end of this spectrum would be an yandere personality, which is driven by jealousy and desire for power over another person. A kuudere personality falls somewhere in-between - often shy and reserved until romantically interested, then aggressive when pursued. Lastly, there's the dandere persona, also known as the "dark side" - manipulative, self-serving, and without empathy or remorse.
