Inside the Castle
Once you get inside the castle talk to the fallen warrior, he tell you that
there's 30 people in the castle that need to be saved. (Also before starting
equip everyone with the Strength rings and braclets you bought at the town
store, to gain more hit points) You can save all 30 People but all you get
is a "seed" from the last people you save. Walk or run if you like
throughout the castle random battle are going to occur anyway. Head to the
stairs and go Downstairs, turn right and follow along the center wall until
you come to a door on the center wall, Go inside. It depends what your Luck
is because as soon as you enter the room you'll be standing the middle of a
purple cloud. Turn left and head upstairs, turn right and continue to head
upstairs. Once you get to the top you'll see dead samuri and one monk in the
corner you can save him if you want, and take the "Passage Key" from the dead
samurai in front of the Buddah statute. Head back Downstairs and go back to
the first floor. Walk along the west wall until you find a hallway, use the
"Passage Key" to unlock the door and head inside.

Continue West until you come to a hallway with stairs, head upstairs and
don't bother with the other rooms unless your trying to find all 30 people.
After you head upstairs follow the hallway until you find the samurai that the
women were talking about and they're being attacked by demons. Help out the
men by defeating the demons, after beating the demons you'll recieve the
"Tower Key." Head back to the main hallway and head to the stairs. There's
a cat standing beside the stairs use the cat to Save and I mean you really
should save. (If your using any cheating device and have Infinite Health, use
this save point and "SAVE" and reset the game without the cheats on. Trust
me you really need to turn them off.) After saving head all the way upstairs
and you'll run into Toki, who's scared out of her mind. Give her the pinwheel
and open the door to the castle tower. Walk Left and go into the room that
you can see from the overhead view, there's boxes stacked on top of each
other. Walk down than to the left to exit. (There's another person hiding
in the boxes when you walk in front of them, help them if you want.) Walk
down the hall South and turn Right at the corner, enter the room to make a
shortcut, the exit to this room is on the far right side. After exiting the
room head north to the stairs and head upstairs. Continue down the hall
until you come to a room. Enter this room and you'll hear someone familier.

Naraku shows up along with Ustugi, After the scene you do battle with Naraku.
I'm tell you right now THERE'S NO CHANCE TO WIN THIS BATTLE. Naraku has a
barrier and no one of your attacks and break it not even the Wind Scar.
Naraku's attack is devasting as soon as it hits you, it should Critcal
everyone and the fight will be over. But if any characters still have any
health left don't bother using your turn to heal everyone just use your
attack and take the damage from Naraku. Because you one has an attack that
can break a barrier (Yet). After losing the samurai come in and try to save
the party and lead everyone out through a secret passage. After the whole
incident, everyone wakes up in a village and no one knows how they got there.
