Kuuenzan

"With the correct timing, higher and further jumps are possible while airborne. Kuuenzan may be activated while attacking in the air."

- In-game text

Kuuenzan or Kūenzan (空円斬), also known as "Sky Spinning Slash", is one of the two special techniques that Zero learns after defeating Split Mushroom in Mega Man X4. It is a spinning attack activated by pressing the attack button in mid-air, and it replaces the original jump attack.
