Not sure how to feel about this.

Hitori is a socially bankrupt school girl, in trying to end her anxiety, she picks up the guitar and plays online under the alias Guitar Hero, three years later she makes no progress until one day she's scouted to join Kessoku Band, finally acquiring friends and earning the nickname Bocchi, Hitori now has to deal with the social aspects of having friends.
Bocchi feels like the ultimate relatable character, as an introvert myself who has a limit in people tolerance, Bocchi can be seen as a release, but considering this is a comedy and much of it coming from Bocchi's freakouts, it can come off as in extremely poor taste; the most infamous scene being the glitch scream which the actress did without sound editing when the thought of social media is presented to Bocchi although her answer is surprisingly accurate.
I'm very much in the middle ground for this as I can see it from both sides, to compare Bocchi to two other anime protagonists with similar traits; her anxiety feels less self inflicted than Tomoko from Watamote but no where near as sympathetic as Komi from Komi Can't Communicate, a season 2 should give us a good feel for where this series is going and how Bocchi will finish as a character.
No dub, but I doubt any actress could replicate that infamous glitch scream.
Final Verdict: I need more time to properly give this series a proper rating, for now it's at least enjoyable.
