To me at least Sonico is way worse. At least Zone-Tan has a personality.
I can't believe I gave her anime two shots after my brother kept hyping it up when it first aired. I still can't believe that he became an apologist until the series finished.
She's not great, she's a really nothing character for a mascot, and that show was awful too
also she spawned Super Pochaco and I don't even wanna start with that
she's just tittys for the sake of tittys
