 Bishamon O Flute
 
 There are two places in there game where a very strange man hanging
 from the ceiling by his feet, stares at you and ignores you. Later in
 the game, after you use the Evil Plate and open the door, he will
 talk to you. The man will now take you (whenever desired), to the
 Dark Realm. In the Dark Realm, killing monsters until two portals
 open; one to go up and one to go down. Keep going down to the last
 level (20th) while collecting all the items in route. There will be
 no monsters to kill on the last level. Open the box to get the
 Bishamon O flute. Keep the flute just before the last fight with the
 Demon King.  
 
 Bishamon Sword
 
 In the Demon Realm (just after you destroy the Ultimate Creation) is
 a save mirror and three doors. Go to the door that resembles an iron
 gate. It will not open at first. Use the Bishimon O flute on it and
 enter. Go to the Bishimon Sword jutting out of the Skull Demon wall
 object and take it. It is more powerful than all three of your
 weapons put together, and it has speed. The sword also has an
 unlimited supply of magic.

What's Your Grade? :
Onimusha: Warlords allows you the opportunity to rate your progress, based on a 
series of points. The perfect score is 30, meaning you have to score all available 
points in three categories: 

Time taken to complete 
Up to 3 Hours= 10 points
3-4 Hours= 7 points
4-5 Hours= 5 points
5 or more Hours=3 points 

Number of demons killed 
0-399= 3 points
400-499= 5 points
500-599= 7 points
600 or more= 10 points 

Number of souls collected by the gauntlet 
0-34,999= 3 points
35,000-44,999= 5 points
45,000-54,999= 7 points
55,000 or more= 10 points 

The points add up as follows: 
0-9= D
10-17= C
18-24= B
25-29= A
30= S 

If you score a perfect 30 and earn an S rating, Kaede will get a special costume of 
her own... and it's quite demonic. Access it from the same menu as Samanosuke's 
Panda outfit.
