stole something outrageous
とんでもないものを盗んでいきました あなたの心です 大変なものを盗んでいきました
Zenigata: "くそぉ、一足遅かったか。ルパンめ、まんまと盗みおって!" (Blast it! I was one step behind him. Lupin managed to steal something again!)
Clarisse: "いいえ、あの方は何も盗らなかったわ。わたくしのために戦って下さったんです" (No, he didn't steal anything. All he did was fight for me.)
Zenigata: "いえ、奴はとんでもないものを盗んでいきました" (No, he stole something precious[outrageous]...)
Zenigata: "あなたの心です" (Your heart.)
Well-known dialogue from the ending of Castle of Cagliostro.
Marisa stole the precious thing is a parody that inspired parodies of its own.
