One rainy night, guided by Mikazuki the cat, Mitsuki rescues an injured man. Mysteriously, Mikazuki seems to take a liking to the man who says he’s come to visit his sister who works in the Leaf Village. Soon after, Team 7 is assigned to back up the Leaf Police Force on a security mission. Their client is a president of a company who is being targeted by a serial killer known as "The Rainy Day Killer."
I surmised that since
you attacked in the rain,
،خمّنتُ أنّه بما أنّك تهاجم في المطر
Weil du nur bei Regen angreifst,

Como atacabas los días de lluvia,
deduje que tenía algo que ver.
Como atacabas los días de lluvia,
deduje que tenía algo que ver.

avvenivano sempre sotto la pioggia,
Supus que, como você ataca na chuva,
Раз ты нападаешь лишь во время дождя,
 то с этим как-то связана техника.
