Himari brings a group of her new classmates home with her only to discover that something is very, very wrong with one of them.
Didn't... some kind of black
mist suddenly appear?
هل... ظهر ضباب أسود ما فجأةً؟

d’avoir été enveloppé

una specie di nebbia nera?
Algum tipo de... névoa
escura apareceu de repente?
Какой-то… чёрный туман
вдруг появился?
