Hunter's Trial:

First enter the left door and go down the stairs.  Take the left stairs and head through the north entrance.  You are now at the Test of Hunters so make sure at least one of your characters has a Bow equipped.  Walk north through the door into the next room.  Walk into the woman blocking the northern door, and the test will begin.  You'll have to hit the ninja in the back with an arrow to complete the test.  Then head north into the next room to repeat the process 2 more times.  You'll receive the Fairy Bow for completing this trial.

Trial of Warriors:

Return to the main foyer and take the right door this time.  Walk through the door on the right then go down the stairs and through the door.  Walk north, and you are allowed to take 2 choices: the shortcut with harder monsters, or the long route with the easier ones.  I recommend the shortcut to gain levels.  You'll get the Holy King Helmet for completing this trial.

Now go to the Holy King's Altar which is between the two other Trials.  Examine the altar, and it'll reveal a set of stairs.  Talk to the Skeleton, and it'll ask if you'll take the Painful Test.  Agree, and it'll attack you.  The R Knight can hit you 4 times a round with each hit draining 1 LP.  Use Nature Dance, Triple Thrust or other maximum strength waza to put him out of comission in a single round.  Agree to continue when has asks.  Walk through the entrance in the back of the room.  Walk up the stairs and open the chest, and the floor will collapse!  You'll now have to fight a battle against 3 Dancers and 2 Clowns.  They'll use Charm Spells the first round to attempt to charm the entire party.  Use hit-all waza such as Great Wheel, Firecracker, Megahawk, or Holo Sword to attempt to wipe out the entire enemy party.  After a couple of rounds, the battle will end.  If you manage to wipe out the entire party, you may win a Heartache.  Walk south into the next room and make your way to the top-middle of the room and go through the exit.  Walk up the stairs and open the chest for the Holy King Boots.

By now, you've heard about the pirate Jackal.  He's killed innocent people, kidnapped children, stolen the Holy King's spear, killed Nora's father... basically, he's not a nice guy.  You probably also know that Maximus is the Jackal if you're asked around, but you can't prove it.  Herman/Black thought he killed Jackal long ago and says he can recognize his face anywhere.  Hopefully, you had taken Herman with you through the Water Abyss Gate, and he'll have become Black.  I'm going to refer to Herman/Black as only Black now.  Take Black back to Pidona and enter the Divine Church's headquarters there.  You'll find Maximus greeting Ludwig.  Black will identify Maximus as the Jackal which causes him to panic.  Jackal escapes, and two demons appear.  Everyone, including Ludwig, quickly flees.  Dispatch the two demons then walk behind the desk that Jackal was at.  You'll enter a short dungeon.  Walk south and then turn and continue to the left.  Ignore the double doors, there are only monsters behind them.  Now walk to the north and turn right.  Walk down the stairs to the next level.  Walk down then turn left.  Enter the double doors this time to get some chests containing a Nut [Shirt], Remedy, Soft, 800 G, and an MPotion 3.

This battle should end rather abruptly and leave you wondering why this was even a boss battle.  You should be able to wipe out Ren Wang in a round (maybe 2 if he uses Nap).  Using waza such as Nature Dance and Split Body should quickly finish him off.  His attacks aren't very strong either and are mainly flame/sun based.  He uses Heat Wave sometimes which will do very little damage (0-10) if you have good magic defense.  There's not much that can be said about him.  You shouldn't even have a problem if you don't have any WP left.

You begin this battle with only your main character.  After fighting for the first 2 rounds, another of you party members will show up.  One will show up each round until you have 5 members.  Then you'll have one round before Maximus "transforms" and brings in his guards.  If you've already sealed the Water Abyss Gate, you should be able to wipe out Maximus in the 4th or 5th round- before all your party members return.  Maximus is not strong at all.  Once he transforms, he has the Holy King Relics at his disposal, but still isn't much of a challenge.  4 Max's Guards will appear with this transformation and are only a minor annoyance.  Use waza such as Nature Dance or Split Body to end Maximus's world domination career abruptly.

With Maximus's death, you'll receive all of his Holy King Relics which are: the Glory Staff, the Masquerade, the Holy King Spear (the one stolen from the Workshop), the Seven Star Sword, and the Devil King Axe.  If you are playing as Katrina, you may now return to Loanne with the Masquerade   If you don't have any room in you inventory though, you WON'T get the relics!

This battle is very easy.  If you want to end it quickly, use waza such as Triple Thrust, Final Letter, or Gold Dragon, and the battle will end in less than a round.  Otherwise, this battle shouldn't last long at all, probably 3 rounds tops.  The Soul Sucker has less than 4000 HP.  It's Dissolve attack does half-way decent damage, but that's about all it can really do.  Treat this monster more like a regular monster if you wish.

Now head to Yousei's tent and walk to the backside of the cage.  Examine it, and you'll open the cage freeing her.  Yousei will fly off without a word back to the Fairy Village in the Ake Jungle.

The Dragon Car can be hard if you aren't prepared for the battle.  You'll only get to use 3 characters, and if any of them die, they are knocked off your car and out of the battle.  The Car can get 2 attacks per round and likes to use Poison Mist against the entire party.  Equiping Hid. Leather armor can save 2 of your characters from the poison.  Use waza such as Nature Dance, Split Body or Golden Dragon, or Final Letter to cause around 6000+ damage per round.  The Dragon Car battle won't be very hard if you keep your HP high and have powerful waza.

This Dragon Ruler is the first you will encounter and also the easiest.  It recovers around 700 HP per round and enjoys casting Freeze Wall on itself.  To beat the Dragon, use high end waza such as Final Letter, Nature Dance, Sky Drive, Split Body, or Triple Thrust to inflict loads of damage.  If you have Turtle Shell Split, it will also make the battle much easier by lowering the Dragon's defense every round.  The Dragon Ruler can do a fair amount of damage with its breath attack and Freeze Wall counterattack, but overall, the Dragon shouldn't pose too much of a threat.

Behind the Dragon Ruler is a small island with the Ice Sword encased inside.  Run over and grab it then head out of the Ice Galaxy.

Walk to the west to reach a chest with a Barrier Stone in it.  Return to the previous room and walk into the room to the east.  Open the chest to get an MPotion 2 then return to the previous room.  Now walk to the north and go through the door.  Keep on the railing and take the exit to the right to be in a small room.  Open the chest for a Demon Belt.  Return to the previous room and walk down the stairs.  Take the exit to the north then, in the next room, take the eastern exit.  Walk along the hallway and take the eastern exit once more.  Now walk down the stairs to enter the lower floor.  Continue walking down the stairs then follow the winding path until you reach the stationary beastman which is an Arakes Demon.  Kill the demons and walk through the door.  Now walk through a hidden door on the bottom-left corner and walk south through the exit.  Walk through the western exit, and go north.  Walk along the mirrored path to reach a Storm Dragon and a chest with a Meteo Frag inside then return to the previous room.  Take the eastern exit to get a chest with Fishscales inside.  Return to the previous room and take the southern exit.  Keep walking south to enter a hidden room with a chest containing 500 G.  Walk north to the previous room and take the western path.  This path takes you to the southern end of the room so that you can access a chest with the White Tiger armor in it.

At this point in the game, Arakes should be absurdly easy.  His enjoys using a fire elemental attack, Rear Burner, which doesn't do more than 140 damage when it hits.  His other attacks don't do too much either.  Use waza such as Golden Dragon, Triple Thrust, Final Letter, Dynamic Hit, or Tiger Break to quickly finish this battle.  For me, Golden Dragon (at level 37 swords) did 4890 damage when it hit.  Arakes should die in no time.
