ONA is the short term for original net animation - know in Japan as web anime and it refers to an animation that is directly released onto the Internet.
Did you know that the series Hetalia: Axis Powers is considered an ONA, because each episodes last for a few minutes ?

In the beginning of the 2010's most ONA's were series with short episodes in length, but in the second half of the decade there are now full series available on network streaming services like Netflix or Amazon Prime Video

Your name is Jonah and you came from the tiktok trend. You're smart and rather quiet but you can open up and be really goofy around the right people. Although you tend to hide your emotions, you are actually pretty sensitive on the inside. You want people to stop trying to change you and appreciate you for the way you are
Carter: Oh hey, Jonah's here!
Ronnie: Dude, that's awesome. Jonah's the man

Ona is a very nice, kind, loving person and very affectionate with other people. It is very easy to befriend her and get closer to her. It's easy to get attached to it and it's hard to let it go, but when it leaves, you'll go crazy.
Ona is chaos
