Have Jacques go through the Phantom Realm in Honnouji.

Complete the game with the Onimusha rank. Alternately, get the Bishamon sword in the
Phantom Realm in Honnouji when Sam goes to the past. To find it, go to the save location
at the foot of the stairs to the temple, then look to your upper left to find the hanging
man. Approach him to be sent to the Phantom Realm. Collect eight Red Orbs to unlock the
chest that contains the Bishamon sword.

Complete the game under the hard difficulty setting. In this mode, only critical hits can
kill opponents.

This trick only works for Samanosuke. Once you obtain the Ten-Point Slash Training Scroll,
play under the beginner difficulty setting multiple times. Each time you finish, you
should come away with one bar, or close to it. Do this until you have the desired amount
of souls, or until you max all your equipment.

Complete the game under the normal difficulty setting with a high score as Samanosuke.
Alternately, Complete the game as Jacques' alternate costume.

Complete the Oni shooting mini game. The game will start with Sam having the Bishamon
sword; Jacques having his best Oni Musou; unlimited arrows, bullets, unlimited Oni power,
thirty Medicines, and ten Talismans.

Complete the game under the normal difficulty setting with a high score as Jacques.
Alternately, Complete the game as Samanosuke's alternate costume.

Complete normal training mode, then complete the game.

This was done under the normal difficulty setting. First, stock up on magic for all your
weapons. Then, stock up on all the Purple Souls. At the beginning, jump behind him after
he attacks. Then, just waste the magic on him. Use every weapons magic until you do not
have any more. After that, use regular attacks. Watch out for the ice attack. Most of the
time the thunder magic from him is off target. After a few regular attacks, transform into
the Onimusha and attack him hard. However, do not use the mega attack yet. After a few
attacks, just before your magic runs out use the mega magic attack on him. If he is not
defeated, then just attack him a few more times.

Complete the game in Critical (Issen) mode.

When playing as Michelle, go further behind near the skull door and throw some grenades on
them.

Complete the game. Heihachi (Honda) is now selectable.

This trick requires the gauntlet for Sam/Jacques to be at least level 2. Charge up the
gauntlet to at least two and unleash a magic attack. With the purple vest on Ako you can
do about five magic attacks in a row instead of four.

This can be done without charging during an Onimusha. Also, block Issen works during an
Onimusha and takes out all enemies.

Equip Ako's White Haori then stand still.

When you are helping Michelle save her comrades, keep pushing the ball as far as possible.
You will see a light in the water.

Complete the game under the normal difficulty setting.

Complete secret training mode. Alternately, play the game with a memory card with a saved
game from Onimusha Blade Warriors.

Complete the game under the normal difficulty setting.

Complete the game with an Onimusha rank. Alternately, play the game with a memory card
with a saved game from Onimusha Blade Warriors.

Intentionally lose the game two times under the normal difficulty setting.

Complete Issen/Oni training.

Ako's Red Haori is required this trick. When you get to the port town of Sakai and the
demons come out to play, equip Ako's Red Haori. Start killing demons with Issen or Block
Issen. Clearing each area of demons should give at least three quarters of a full soul
bar. The port area is most lucrative (one full bar every time because of the fish
demons). The Issen is not necessary, but it is most effective. You can upgrade all of you
present weapons to full with this trick, since one level 2 weapon/equip requires about ten
bars to level up to maximum.

Any of the three Dark Realms can be easily bypassed. This requires some skill, Ako's
Purple Vest, all weapons for the character, and all weapons been completely enhanced.
Whether or not the gauntlet is completely enhanced is irrelevant. Before entering the
Dark Realm, equip either Chigo (for Samanosuke) or Hyosai (for Jacques). The enemies that
attack will appear in multiple waves. Just wait for all enemies to appear, then execute
one magic attack. Absorb all the souls that appear. Ako's Purple Vest should allow you to
do this as many times as necessary. However, if you are fighting large demons, you may
need to get up close with either the Tenso (for Samanosuke) or the Enja (for Jacques).
Note: A crucial part of this strategy is absorbing the souls. If you feel that you need
Ako's Blue Vest as well, make sure to switch back and forth as appropriate. Also, it is
much easier to go straight for the bottom part of the Dark Realm that you are in, as the
tougher enemies are down there first. By doing this, you can use your magic efficiently
on the tougher enemies and not have to worry about the weaker ones.
