As Akari's summer break has finally begun, she wracks her brain to come up with fun, summery things she can do together with Sophie.
However, the ocean or anything outside are all a bad fit for a vampire like Sophie.
Then she has a moment of clarity and realized that a firework festival is at night and a summery activity, so she immediately begins preparing yukata.
Erie and Hinata and join them to go to the festival, however...
I'm standing alone under this tree.
.أنا أقف لوحدي تحت الشجرة
Ich steh gerade ganz
allein im Baumschatten.
Estoy aquí sola bajo el árbol.
Estoy aquí sola bajo el árbol.
Là, je suis seule,
à l’ombre d’un arbre.
Sono qui da sola all'ombra di un albero.
Estou aqui, sozinha, 
embaixo desta árvore.
Сейчас я одна под этим деревом.
