Here we have a Bnha oc by the lovely EtherealCity, who has been nothing but a pleasure to work with.

My comments will be in bold

Basics and grounding

Good, there isn't enough characters like this and my main mha character is like this. She used to be heavily involved in the canon plot but I scrapped that because I think characters that are only loosely linked to canon have more freedom and you can be more creative with it.

Character information

For a character that isn't meant to be finished, this character has more description and thought behind it then a lot of completed characters I've seen. I really like the sound of this character so far and she seems pretty unique in her design. You see a lot of characters that don't utilise the fact that they can make their characters however they want.

You say she's curious and all I have to add there is if you ever write a piece with her in then make sure you show this and display this through her actions.

However, I do have a note on something, when writing/filing in a form for someone to review, don't compare it to other characters because it sounds like you're trying to say your character is better than others. I'm not saying that you are, but reviewers aren't interested in other people's characters whilst reviewing yours, and if your character has a unique trait, the person reviewing will probably notice.

Relationships

This is interesting, introducing a cult into the bnha universe makes sense and could work as long as it's well written and you do research about the brainwashing of cults and what goes on in them.

As for a crush, I'll address that later, but I often recommend shipping your character with an oc. However, I am a fan of oc x canon if it's done well and I'll give my views on potential ships later on since you've requested my opinion.

Backstory

An interesting backstory, apart from so needed further development, this is pretty good and it's nice to see a potential new angle to this universe.

Other

I actually really like this quirk and everything here makes sense so, once again, all I think what's needed here is some further development.

Also, Florence and the Machine is a great band so good choice.

Stats

Since there is a 5 here, I recommend having at least one 1 stat to balance it out and keep the character level.

Extra

I like seeing odd random facts like this for characters because it means a lot of thought has been put into it so good job.

There's of course a colourful cast of characters in bnha so I'll say my take on who I think she could get along with. I think she could be great friends with Koda, that's the rock guy in class 1A who talks to animals.

I feel like she has the potential to be shipped with Todoroki or maybe even Kirishima or Shinsou. A softer character would suit her, but I feel like someone who opposes her, like Shinsou, could work too. And whilst I ain't a fan if trauma bonding, she could relate with Todoroki on her struggles. If you want to go for someone less mainstream, then I recommend a character from class 1B, even if I'm not sure who.

Final thoughts
This is a really good character and with a little further development she could become an even better character, so good job!
