Head to Fortuna Castle
Opera House Plaza
Destroy Scarecrows at the courtyard using High Roller and Red Queen combinations. Break benches to get Red Orbs. Get out through the green door.
Take the Gold Orb from the alcove (you will need to use Kick Jump to reach it). Run upstairs, leaping over the gap. In the small storehouse you will be attacked be a few more Scarecrows, destroy them and leave.
There is not much to do in here. Run forward, then left and through the door. In the cathedral destroy all the chairs and get Red Orbs. Take the Evil Legacy from the centre of the hall. You will be able to use Grim Grips - blue blinking points. You can also take items which were unreachable before - try it to take Vital Star S on the other side of the bars. Use RB+B (or space+L) combination. You will also use the same combination to grip points above. Stand in the blinking circle on the floor and use RB+B (or space+L). Before you leave, kick jump over the gap and take a Red Orb.
Move along the balcony using Grim Grips. You will reach the statue with a red mark - it will teleport you to your first secret mission. In any case, use Grim Grip, destroy Scarecrows on your way and leave this area through a door.
Secret Mission 01: Annihilation
Destroy all the demons in one minute.
Tactics: use a High Roller, then catch the enemy with Buster.
Go down. In the narrow street you will meet a few Scarecrows. Destroy them and then do the same with a Red Orb statue. You should notice a small Red Orb near, take it and then take another. Taking Red Orbs will lead you to the Blue Orb Fragment. On the courtyard you will notice a wooden watchtower, Kick Jump on it to get some Red Orbs.
Port Caerula/Customs House/P. Caerula
Go right and take a hidden Red Orb using Kick Jump. Then go to the pier and use the Grim Grip there. Destroy Scarecrows and attack the blue glowing mechanism. After a few blows the blue barrier will disappear. Go out through the door and use the control panel. Go back to the pier and enter the cave.
First Mining Area
Go along the corridor, jump into the water in the big room to collect more Red Orbs. Then go up using your harpoon and Grim Grips. Take the Green Orb and accept the fighting challenge. You will have to reach a Brutal level to destroy the statue and get a Blue Orb Fragment. As usual, High Roller + Buster combo is your friend here. Buy some skills or items and leave to fight with Berial.
This fire demon can be a little hard to defeat, but only when you panic and start attack blindly. Try to stay in the air and above his neck (use Snatch skill). Attack him till he stops burning, then use Buster to smash him into the ground. Try to do it two times in a row. Uh oh, he gets pissed now so be careful and avoid his attacks or, as before, try to stay near him.
