Windmill Shuriken:
------------------
You can get the Windmill Shuriken when you first enter the Pleasure Street area.
Walk forward down the street; you may be attacked by three Black Spider Ninjas.
Defeat them and continue. You will reach a large clearing. Do not go too far into
it yet. If you do, some motorcycle soldiers will attack and you will not be able
to get the Shuriken until you defeat them. Instead, turn to Ryu's left. You will
see some smooth areas on the wall bordered in blue going down an alley. To get
the Shuriken, wall run and jump to each of them, getting progressively higher
each time, and land on a raised platform on the last jump. This may require a
few attempts. Sometimes it will seem as though you will fall off even if it
appeared like you should have made it. There is also a black object up there that
will fill your health and Ninpo. It can also be used at a later time if needed.
Easy Essence:
-------------
In Chapter 12: The Aquaducts, go in the room where you are attacked by the
oversized beetles. Use the Art Of The Imzana Ninpo as many times as possible to
get about 5,000 Essence.
Defeating the motorcycle troops:
--------------------------------
Use the Guillotine Throw to pull them off the bikes. If you do not have that
technique, another good way is to jump around frequently, trying to avoid being
hit, and to attack them with the projectile weapon of your choice whenever you
land.
Note: The motorcycle soldier with the sidecar cannot be grabbed with the Guillotine
Throw.
