Polygraph

Polygraph is the Quirk used by Makoto Tsukauchi.

Description
Polygraph allows the user to judge the authenticity and genuineness of their target's words, telling them if they speak the truth or if they are lying. The condition for this Quirk's activation is direct physical contact with their target.

Weaknesses
The power is vulnerable to technicalities, as shown when Koichi was able to successfully lie to Makoto because she got his Vigilante name wrong when asking if he was "The Cruller".

Trivia

 * All For One is revealed to have a similar lie detection Quirk he stole from an ancestor of the Tsukauchis, which has grown more powerful due to mixing with his other Quirks. Said Quirk can detect hostility and ill will concealed inside people's speech.
