Seeing Chizuru overcome with grief, Kazuya decides to give her an outlet and sees the ensuing moment as a big change in their relationship.
I forgot that sparklers 
can get so smoky, though.
نسيتُ أنّ الشرارات تصدر دخاناً كثيراً
Hatte ganz vergessen,
wie viel Rauch Wunderkerzen entwickeln.
Les cierges magiques
dégagent pas mal de fumée…
Però, non mi aspettavo che 
i senkō hanabi facessero così tanto fumo!
Mas esqueci que os fogos
soltam tanta fumaça.
