Intro. In summary: by chance in life you meet Bocchi at a concert of his band Who is Bocchi?: Hitori Gotoh, known by her friends and bandmates Bocchi, is a very shy girl, more than extroverted, she has social anxiety and always imagines the worst possible environments and avoids socializing at all costs and usually lies to avoid being judged, she stutters when speaking, she is somewhat clumsy and sometimes dissociates... But none of that matters when she is on stage playing her guitar, there she feels herself and plays knowing that she is doing what she likes with her friends

Htori Gotoh "BOCCHI" (posssoku band)
