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!
"I'll uphold my promise with Kai-chan 
and become friends with her again!"
سأحافظ على وعد مع كاي-تشان"
"!وأصبح صديقة لها ثانية
Das Versprechen einhalten
und mich wieder mit Kai-chan vertragen!
"¡Mantendré mi promesa con Kai
y volveremos a ser amigas!".
"¡Mantendré mi promesa con Kai
y volveremos a ser amigas!".
« Je vais tenir ma promesse
et me réconcilier avec Kai ! »
"Manterrò la promessa e tornerò amica di Kai"!
Mantenha a promessa e faça
as pazes com a Kai-chan!
Я исполню обещание,
и мы с Кай снова будем друзьями!
