The Lock

The Stand looks like an enormous U-shaped padlock, its face engraved with the character for money. It clasps onto a target's heart and appears sunk into their chest, and as with most Stands only those with powers of their own can see it, the victim included having no clue it is there. Tamami can also carry it around as a solid object, as he did when Rohan Kishibe summoned him to prove Josuke was cheating at dice. Colored art shows it brown in the manga and a metallic grey and red in the anime.

An automatic Stand with no fighting power, The Lock suits Tamami's small-minded schemes and turns genuinely dangerous by nudging its targets toward suicide. Once he stirs guilt in someone, he can call up the Lock inside their chest, and from there their guilt compounds without pause, stacking with fresh accusations as the Lock swells larger and heavier. It lingers on indefinitely even far from Tamami, lifting only when the victim is driven to take their own life, when Tamami chooses to release it, or when the cause of the guilt is removed, usually by paying him off or by realizing there was nothing to feel guilty for. He can plant guilt over imagined wrongs and burden several people at once, though the pressure can be undone from the other side, as when Koichi coaxed his mother out of her guilt and lifted the Lock. Tamami claims that harming someone bearing the Lock rebounds on the attacker, though that is never shown. The Stand can also read honesty, moving when it senses a truthful person and holding still against a liar, a trait that surfaced during Josuke's dice game with Rohan.

Tamami Kobayashi, a petty con artist of Morioh, is the Stand's user. Koichi Hirose and his family were among the first caught by it, with Koichi eventually learning to shake its grip on his mother.
