It depends on what you mean.
Are you looking for a non toxic version of Ena who likes her fans.
If you want someone who constantly upbeat high energy back and forth argumentive banter with chat and enjoys being put in her place b/c she is a bit of a masochist, Lumi from phase connect.
If you are looking for a no nonsense loli baba with drunken wife beater energy who still actually banters and cares about her fans, Tenma is your gal.
Uruka has the self deprecation low key masochism boiling under her girl next door persona that is strangely erotic.
Pippa is very bipolar, and her lows are very similar to Ena's lows. Pippa's highs are very bratty and very edgy humor, like Ena. But even at her worse, Pippa still cares and appreciates her fans, her hatred is mostly pointed at her self.
Lia has Ena's combative side, she almost always fights with chat and likes to torcher chat by reading bad yaoi fanfics and other similar stuff. Lia has a big self destructive streak, like Ena. So if things are going to good, expect a biggish yab. But unlike Ena, her tabs tend to be mutually destructive or more self harming then attacks on chat. She has serious self esteem issues she hides behind her high energy zoomer tumbler personality.
I hope this helps you find another oshi, I mostly jumped ship to phase connect myself.
I too was a fan of Ena, not sure if I am still her fan because of the drama of the last month especially her attacks on fellow niji girls.
I still like Selen, Pomu, Elira, Finana and some of the other nigi girls, but it feels like nijisanji is a sinking ship.
I liked Ena, she is a beautiful singer. Self hatred is fine, hilarious even, but you don't shit talk your fellow talents. Managers and staff are ok to shut talk, but never other vtubers in your org.
