is it perhaps the fact that she became a sailor senshi at thirteen, a whole year before anyone else? the fact that she was alone and kicking ass with no backup, and managed to kick the dark kingdom out of an entire country despite that fact?
how about because she’s the leader of the guardian senshi, the princess’s decoy, and thus had to learn statecraft and everything that goes into being the heir of a system-spanning empire, PLUS bodyguard training and her own duties as crown princess of venus? or the fact that she has a crush on one of prince endymion’s guardians, but kills him regardless of her own feelings when he helps lead a rebellion against the moon?
what about the fact that she is simultaneously fun-loving quirky romantic ditz AND the hyper pragmatic quick thinker, the planner, the one who is her princess’s sword and shield and greatest general? or the fact that she is destined to never fall in love, despite being the human incarnation of aphrodite?
there are as many reasons to love venus as there are facets to her personality
