Ostania's counterintelligence agency and national security bureau conducts spy hunts and keeps surveillance on its citizens to maintain peace within the country. They are also called the Secret Police and are feared. Yor's younger brother Yuri actually belongs to the Secret Police and is hunting down spies while keeping this a secret from Yor and others around him. One day, he suddenly shows up at the Forger residence. The Forgers, who are full of secrets, and Yuri, who has a secret identity, come face to face!
If he's some shithead who's threatening my 
sister, I'll throw him in a cell immediately.
،إن كان وغدًا يهدّد أختي
.فسألقي به في زنزانة في الحال
Wenn du Mistkerl meine Schwester
malträtierst, kommst du hinter Gitter!
Si es un delincuente que pone en peligro
a mi hermana, lo encarcelaré.
Si es un canalla que pone en peligro
a mi hermana, lo meteré en la cárcel.
Si tu as osé la maltraiter,
je te bouclerai sur-le-champ.
Se dovesse rivelarsi un bastardo che mette in pericolo
mia sorella, lo sbatterò dritto in cella!
Se ele for um idiota ameaçando
minha irmã, vou prendê-lo na hora.
Если ты, сволочь, угрожаешь сестре,
сразу же отправишься в тюрьму!
