Boomerang

Boomerang is a Quirk used by an unnamed Ketsubutsu Academy student.

Description
This Quirk seemingly allows one to change the trajectory of thrown objects. The projectiles also appear to get homing properties.

The projectiles are not unstoppable though, even if they're as hard as concrete. A viscous liquid can easily interrupt their path.

Named Techniques

 * Trajectory: Crescent Moon (軌道弦月): Hardened projectiles are thrown underground, where they travel in a curve towards the target while keeping their trajectory concealed from view.
