Back in my day people called these "kin lists", but I never clicked with that term 100% honestly. I am not identical to any of these guys but they mean a lot to me!
I'm adding descriptions when I have the time, so ignore if you can't click/read about anything right now!
Main Connection 
Basically what you'd consider a "kin" in the modern day LOL. I relate to these guys very strongly.
Utena Tenjou
Oh Utena…where do I even begin with Utena. I have never seen myself in a character as much as I have with her, her struggles with identity whether it be through her initiative in life, gender, or the very ideals she’s been living up to the whole story just, hit incredibly close to home for me. I also find her to be an absolute beacon of hope and change that I aspire to be like one day. I also find her development and especially her reaction to traumatic circumstances incredibly true to my own experiences. I really adore them so so much….she means the world to me!!!
Rapunzel
Tangled is my favorite disney princess movie and I’ve been associated with Rapunzel via family influence for years. I also just relate to her development and struggles a Ton. She’s also just really similar to me personality wise LOL. We got whimsical silly creature going out into the real world for the first time. She’s also a creative masochist like me so YIPEE! AND SHE GOT MY HAIRCUT!!!
Ena Shinonome
While initially I found myself drawn to Kanade when getting into Project Sekai, it was Ena’s story that absolutely captivated me and made me feel so seen, especially as someone pursuing an artistic career. Her development as she gains true confidence in her abilities, seek actual improvement instead of just chasing after the approval of others and learns to love making art again is just. So. So Real. She is so special to me. I genuinely cried reading Ena6 LOL. Even if you don’t like gacha games (which. Fair) please watch the pjsekai stories on youtube! They’re genuinely so well written its insane and Ena’s not the only one :3
Secondary Connection 
Decent amount of connection! But I usually relate to specific aspects of them rather than their characters as a whole.
Tertiary Connection 
Relate to them a smidge, but mostly enjoy them because they're comforting! Also for characters I related to in the past, but not so much anymore.
