No premiere date announced yet. Check out the ANN article for additional information. Synopsis from AniList:
Always ready for a fight! Destruction for destruction’s sake! The online streamer Aoringo is a troll, making the worst of the worst of boundary-pushing flamebait content and raking in the revenue from the hate-watchers. You may think he’s nothing more than a bottom feeder and a drain on society, but in reality, he’s high school dropout Souji Enishiro, a caring older brother with a sweet tooth who loves nothing more than his little sister. His viral videos? Just a way to pay his sister’s medical bills. And even if all of humanity hates him, he doesn’t care, so long as his little sister gets better. But then, something very strange begins to happen…
Something to note here is the one of the cast members announced is Fairouz Ai, who had previously announced a hiatus to her activities. So, this is hopefully a sign that things are improving on her end as she is one of my favorite VAs.
