Truth Bullet Example 1
Truth Bullets, also known as Verbal Bullets (コトダマ Kotodama), are an item featured in the Danganronpa series. They are used during Class Trials to "shoot" your evidence at a weak point in someone's argument. You gain them during the Investigation Period of a case. As new information pertaining to the case is discovered, Truth Bullets may change. 

Danganronpa 2: Goodbye Despair introduces a similar mechanic called Truth Swords during Rebuttal Showdowns.

Truth Bullets and Truth Swords return in the game Danganronpa V3: Killing Harmony, where a new Lie Bullet mechanic is added.

Unlike in the main games, Truth Bullets are used by Komaru Naegi in Danganronpa Another Episode: Ultra Despair Girls to shoot at Monokuma Units.
