Their last name is Hasaki or sm. I didn't feel like drawing Jupiter so u got Venus. I'll draw Jupiter later (Lololol no I won't)

A bit about Venus:

If you saw Heroes Rising, this is kinda hard to ship this because of what happened. Anyways, she was born several years after Heroes Rising's setting (shhhhhh I know what happened-)

Lololol I forgot half of the movie so half of what I write is barely a spoiler unless I say so

She has Nine's original quirk and she acts like him a bit. She wears a mask like Nine does but it's more of Chisaki's hospital mask not plague doctor. She is a narcissistic sociopath who only cares about herself and thinks she's a goddess compared to everyone else. She's a villain like her fam.

Her younger brother, Jupiter can make natural disasters and hurricanes (Lololol he's a red head because he looks like the planet-)

She is the heir to Nine's cause and has murdered someone.

There's a lot (no there isnt) I can't say about her or Jupiter without it being a spoiler. Here's a list-

Venus's quirk
Where they were born
What they fight for
Why Venus is wearing a jacket (no reason lol-)
And that's pretty much it.
