April. A young girl stands alone, acting suspiciously in front of the entrance to a middle school... That girl is Hitori Bocchi, a new first year student at the school. And starting today, she's going to become friends with everyone in her class... hopefully!
After all, you've never 
once broken a promise!
!فقبل كلّ شيء، لم تخلفي وعدًا قطّ
Du hast nämlich noch nie
ein Versprechen gebrochen!
Al fin y al cabo,
nunca has roto una promesa.
Al fin y al cabo,
nunca has roto una promesa.
Tu n’as jamais trahi
une promesse, Bocchi.
Perché tu, Bocchi,
non hai mai infranto una promessa!
Afinal, você nunca quebrou
uma promessa, Bocchi!
Ведь ты, Ботти,
всегда выполняешь обещания!
