A humanoid guardian spirit possessing butterfly wings and antennae, Janomecho is said to have a strong connection with death and the soul, and that all who speak its real name die—hence why people call it lanomecho, a type of butterfly known as "minois dryas" in English. Samurai would often pray to it before heading into battle, believing it would bestow great power upon those willing to risk their lives for glory.
Sends out a Tornado that repeatedly hits anything it touches. The Tornado persists for a fairly long time and applies the Wind element incredibly easily. The Tornado also applies a brief stagger on every hit. Very good against large Yokai.
