Hibiki gets lost when she's forced to walk to school alone. While angrily thinking about how Ren refuses to accompany her, she begins reminscing about how they first met and became friends...
And so we started going 
to kindergarten together...
...وهكذا بدأنا نذهبُ إلى الحضانة معاً
Und seither gingen wir
immer zusammen in den Kindergarten.
Comenzamos a ir al jardín juntas…
Comenzamos a ir juntas a la guardería...
Ainsi, nous allions
à la maternelle ensemble.
E così iniziammo ad andare a scuola insieme...
Então, começamos ir para o jardim juntas.
