A Himedere refers to a character who wishes to be treated like a princess by the person she loves, even if they aren’t actual royalty. Himedere characters have a princess complex.
Himederes demand to be treated like royalty by their loved ones, even if they are not royalty. Himedere characters are very similar to tsundere characters, but by no means too "princess-like" to be a "Tsundere variation".
They usually get any kind of work to be done by other people, giving orders to everyone around them. They put themselves first in any situation, not caring about others, except the one they love. They always want perfection and success everywhere, from everyone and themselves.
Himederes may have a history that shows the root of their insecurities. Specific moments of abandonment, neglect, and betrayal have commonly been the cause for the himedere's behavior. The purpose of a himedere's backstory is to explain what triggered their attention-seeking behavior, and who in their life is sympathetic to their past.
A himedere can be truly befriended by the few who can see past their ego. Sometimes the himedere takes their companions for granted and chooses to treat them unfairly. Those who tolerate her either let the himedere walk all over them or retaliate eventually, but there is usually a sense of loyalty or a strong bond that is difficult to break.
This type of character is one who has traits of a stereotypical, snooty princess, and comes off at first as arrogant, self-centered, and vain. Still, they have the capacity for love and friendship and often will soften over time, learning a valuable lesson in the process. The male version of this is Oujidere.
Himedere character's behavior is like a spoiled brat but with a princess complex. The kinder and more mature version of this dere is oujodere.
