Here is another section of the game that features "dead time" until Dante starts the next mission. For starters, you may want to do Secret Mission 7 Water Prison by swimming back to the Captain's Room and investigating the Captain's skeleton - note that this is the only time you can do this.

You should also investigate the room where the Untouchable was (in the ship) and get a Blue Orb shard (this the other entrance apart from the one that leads out from the ship). Another thing to do is to get the Blue Orb shard in the shallow pool when you leave the confines of the ship and water.

When you're ready to do the mission, head up the stairs and open the door. Head through the corridor and turn left. Circle around the corridor and head to the end. A skeleton holds an Emblem Shield you need to get. Pull the skeleton's arm when asked to open up the exit.

Although you open up the exit, you also set off a booby trap, so jump to avoid the spikes that rise from the ground. Head for the gate and ride the elevator up. You appear by a waterfall.

A Blue Orb shard is on the ledge above the elevator; a Holy Water is at the waterfall's bottom, and a yellow stone is at the waterfall's top. Do what ever you want then head out the waterfall's cave and go down the cliffs in the next area. Look for a mine shaft and use 200 Red Orbs to head through the door.

There is a green stone and a Orb Vase in the same area, and there are three cave entrances available. The top one leads to the waterfall, the middle one to the bridge (and orb vase) and the last one to the exit.

Kill all the monsters in the next area. After killing all the enemies, surrender 100 Red Orbs to the next door, which ends the mission!
