Note: I lost a ton of requests because I went through and deleted a ton of posts. I don't plan to do any more requests (I am super burnt out at the moment), but this was already written. I have a saiki x gn online reader headcanon list half written and may finish it at some point.

Anyways let's get started

As someone who is so desperate to be normal- he doesn't understand why you would want to make yourself look less normal

What Saiki does understand is that you enjoy it

To be fair he sort of changed the normal to prevent him from having to change his hair color

Maybe he is just annoyed by any judgmental thoughts he can hear when you are out in public together.

He likes that your music isn't mainstream, it lets him experience something new for once that is not a headache- or something that can be spoiled.

You have definitely dyed his hair black before, it took a lot of coffee jelly to do it (and slight compliance on his part due to interest in a more normal look- he hated it and his hair was back to bright pink the next day).

You fit right in with his friends for sure

Kaido may have mistaken you for a member of a dark reunion (he challenged you to a fight before Saiki had to get involved)

You go to Kusuo's school and decide you want to decorate your uniform? Well that isn't against school dress code (Supernatural Saiki related powers may or may not be involved)

When he told you about his powers you asked to be shape-shifted into a bat, a crow, or some other really cool animal

He said no

You convinced him one time and somehow managed to get yourself into some sort of mess ("good grief")

For Halloween one year you both switched color palettes

You put on a pink wig ("I could have just changed your hair for you." "But this is more fun!")

And he turned his black again

If you got sad that you weren't able to dye it this time he would have changed it back to let you dye it just this once

You had a lot of fun putting his outfit together from your wardrobe

"Why do you wear so many layers?"

The makeup was even more fun. He made the executive decision to wear his germanium ring so he wouldn't have to hear your constant thoughts of: "He looks so cute", "adorable", etc.

He did refuse to wear any sharp jewelry as he didn't want anything to accidentally put a hole in his gloves. That would not be fun.

All in all, you guys are just chilling

The most attractive thing he finds about you is the fact you respect his desire for peace and quiet
