Onimusha: Warlords/Keep

Open the door of the main building to enter. Inside is a massacre. There is a warrior genma and taller samurai in the room as well. Defeat them and begin exploring.

The first door on the left leads to a corridor filled with warrior genma. It ends with a door locked by a dual thunder barrier. This door leads to a room filled with ninja genma and a new door. The door leads to a room that has the Blue Book and a secret passage activated by a shrine of 3 orbs ,including the still unobtained wind orb, in the corner. You need to have stronger orbs so this is an area that can't be passed yet.

The second door to the left of the main entrance room leads to a small room with a shrine that generates blue souls. There is also a magic mirror and a chest with the Keep Map inside. At the end of the room a strange man will fall from the ceiling to stare at you.

A new enemy
A man trying to catch a boy is found here. He recognizes you and introduces himself as Tokichiro Kinoshita of the Oda clan. After failing to recruit you against the Saito clan he laughs and walks off. The room has 2 new exits and a chest that contains Normal Arrow. The large iron door leads to where you came from.

The wooden door leads to a dead end room filled with weapons. There is also a chest with Journal #3 in it.

The fire orb locked door leads to a room filled with ninja genma and another door. Behind that door is a corridor that leads to a strange looking locked door that needs a part of an image to complete

Walking further you encounter Kaede and Yumemaru. He refuses to say why the other samurai was after him and runs away. Kaede agrees to go after him. The end o f this hallway is another door. At the end of this hallway there is a door and right path that is not clearly visible. The door leads to a dead end room with a well and a trick treasure box that contains a Bow and the book Suzaku on a nearby bookcase. Attacking the rope in the well will make a pail fall to the floor below. Leave the room and go around the corner to a staircase. Grab the Herb from the nearby chest and go upstairs.

Upstairs
The large room upstairs has a tall genma and ninja genma inside around the corner. There are 3 doors to choose from: One by the stairs, a metal door around the corner, and a dual fire orb locked door.

The door near the stairs leads to a dead end room with a well. You will need to come back here later so move on.

The fire orb locked door leads to a book filled room. In the chest on the floor is the R. Crest Piece and Red Book is on the corner of the table near it. There is a trick door in the back of the room around the table but can not be used from this side.

The metal door leads to the upper area of the first room in the keep. There is a door up here with a fire orb lock. Behind that door is a room with soldier genma crawling up out of pits and a tall genma. The next room has breakable wooden boxes that reveal a chest containing Normal Arrow. Follow the staircase up to find a room with a magic mirror, Normal Arrow in a chest, Byakko, and a double fire orb locked door.

Caged
Behind the fire orb locked door Kaede shows up and shares details on the boy. They are both suddenly trapped by falling bars.
