腹黒い
Meaning
Scheming, black-hearted — someone who appears nice on the surface but is cunning and manipulative underneath.
腹黒い describes someone whose outward friendliness masks calculating, self-serving intentions. In anime and manga, the 腹黒キャラ (black-hearted character) is a popular archetype — smiling politely while plotting behind the scenes. In real life, it is a strong accusation that goes beyond simple 裏表 to imply active manipulation.
Examples
- あいつ笑顔の裏で腹黒いこと考えてるよ、気をつけて。 Watch out — behind that smile, he's scheming something shady.
- 腹黒い人ほど第一印象がいいから怖いよね。 The scariest thing is that scheming people tend to make the best first impressions.
- 腹黒キャラが実は一番人気あるの面白い。 It's funny how the scheming characters are actually the most popular.
