Tenpengusa

Tenpengusa (天辺草, lit. Heaven's Grass), also known as "Wayward Stars", are Mushi that live in the sea of stars that exists parallel to the River of Light. They resemble comets with long tails, and feed from weaker Mushi in the sky. Occasionally though, when prey is scarce, they will lower their tails down to Earth to try and capture prey there.

Weakness
