Park Jimin ✖ Sailor Moon
I think Jimin is a shoe-in for Usagi. They have so many characteristics that are similar from adorable clumsiness, all the way down to loving and compassionate to those around them.
Usagi always looks on the bright-side and believes everyone has some good inside of them, I feel Jimin shares this belief. Even when upset he chides people to turn their life around, never outright condemning someone. When someone is hurt or needs a little bit more help, Jimin is always there, worried and ready to do whatever you need to help. Just as Usagi would give anything, including her own life, to help the ones she loves or even those who she had just met.
With their friends they are both balls of energy. Both have this way of picking on their friends in playful banter that always ends up backfiring and they become the ones picked on, but it is always in good fun. Family and friends are important to them and they always strive to do their best, even when they think they are bad at something and have no hope of ever getting better, they still try. Neither one refusing to give up.
