Tsundere (EntityClass, 7)

From Compile Worlds

The tsundere is a very common archetype that people tend to either love or hate. As you may know, they may either be mainly tsun-tsun, dere-dere or equally both. Romance tsundere usually have issues with their love interest while still being nice to other people. Non-romance tsundere usually have a hard time acting nice with pretty much anyone, but are actually kinda squishy on the inside. Of course, the inverse for each is also true.

For some reason, many tsundere wear their hair in twintails.
