Go right and search an alcove for a smoke bomb. Go around the far left corner of the room and take out the demon. Ascend the staircase and crouch near the top. Wait for the monk to look away and either bypass him or eliminate him. Look up and to the right and grapple to the upper level. Scamper quickly to the wall in front of you to duck under the monk's vision. When he looks away, take him out.
Maneuver through the next series of tunnels and take out the monks and demons along the way. Search the left side of the path for a small health power-up resting on some boxes. Drop off the ledge on the right side of the route and take out the female guard. Leap up the ledges in the corner, then drop down to the floor below. Go around the tower and the hole to a second tower. Look at the top of the second tower for a health power-up. Ascend the ledges in the corner.
Move around the corner to the left and avoid or eliminate the monks. Grapple up to the door at the far end of the path to meet the mission's boss--it's Onikage! This boss resembles Onikage's second incarnation. Don't let him replenish his health with power-ups. When you have him near death, keep the pressure on with combos or damaging items, such as a grenade or sticky bomb.
