My youth is the blue sea

Kamishiro Shiro: “Let’s experience the sea and youth with a cup of oolong tea!”
Police: "Hey, we know this. The question is why aren't you wearing clothes?"
Kamishiro Shiro: “?((〃????〃))???Youth doesn’t need those things!”
Policeman: "Okay, in that case, it's part of youth to experience the pork chop rice in our office."
