I Changed After Going to the Human World

It is obvious that four children are fighting against the queen of wits and courage, but when they grow up, everyone has achieved something, but unfortunately everyone has changed. The upright eldest brother became the evil-doing demon king, the kind-hearted second brother became the ruthless demon emperor, the innocent and harmless third brother became the cruel and bloody ghost king. Only the sister who was protected by the eldest brother and several younger brothers was still the eldest princess in the heaven, but is that just that?
