Kagura Sohma (Fruit Baskets)

From Animepedia

A few years older than Tohru, Kagura violently declares her love for Kyo. Usually sweet and caring, Kagura is quick to snap Kyo back in line. She believes they are meant for each other because they do not transform into their Zodiac animals when they embrace. That, and the fact that she threatened Kyo with death if he did not agree to the bargain.
