A discreet investigation with 極秘

Detective Mouri’s favorite idol, Yoko, comes to his agency after receiving threatening calls and candid photos. Her manager hopes to keep the matter quiet to protect her image.
- 毛利:
- 「承知
( しました!極秘( に調査( するとしましょう!!」- “Got it! Let's investigate this discreetly!!”
- ヨーコ:
- 「あ、ありがとうございます!!」
- “Thank you very much!!”
Key Points
1極秘( = “strictly confidential”
- In this scene, 極秘
( に means Mouri will handle the investigation very discreetly and keep it out of public view. - The 極- part adds intensity, so this is stronger than just saying something is merely hidden or private.
2Adverb use: 極秘( に 調査( する
- Here 極秘
( works adverbially with に, modifying 調査( する. - The full idea is “to investigate in a highly confidential way”.
3〜するとしましょう softens the declaration a little
- Rather than a blunt 調査
( します, 調査( するとしましょう has a slightly performative “all right, let’s proceed that way” feel.
4承知( しました is formal and businesslike
- 承知
( しました is a polite “understood” often used when accepting a request or instruction. - That formality matches the client-facing situation, even though Mouri’s double exclamation marks show his excitement.
