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...
Since vampires don't have a body

temperatura corporal como los humanos,
Los vampiros no tienen

Como vampiros não têm temperatura
corpórea como vocês humanos,
У вампиров нет температуры
 тела, как у людей,
