The myriad celestia featuring Acheron (who only showed up for 2 seconds) was the biggest nlothingburger possible. Just another "look at the generic bad guys you will only see in 10 years" like the IPC and Everflaming mansion videos. And now Acheron's lore and plot are tied to some shitty male who fans keep sucking off and shipping with her. It's just another Crapitano x Mavuika. Nothing about Frebass. This is the worst direction they could have taken.
Hoyo really never fails to disappoint. At this point I won't be surprised if they add another Otto expy at the Yae planet, concidering how much they now love to shill males and tie women to them
