Chaz is the main character (after the bad thing that happens to Alys). He was living on the streets until Alys picked him up and taught him the ways of hunting. He's a swordsman, and the strongest character when it comes to physical strength.

Alys is quite the famous hunter. She's your typical comic relief/won't do anything for free female lead (like Lina Inverse from Slayers). However, she doesn't remain the leading character for long because something bad happens to her. She uses a nifty bladed boomerang as her weapon. It damages all the enemies on the screen at once.

Hahn is an assistant at the Piata academy. His idol is Professor Holt who disappeared when he went to inspect Birth Valley. He joins your battle party before you enter the academy's monster-infested basement. Hahn just plain sucks. His attack/defense is low and his arsenal of attacks only consists of basic or low-level techniques. I popped open a bottle of champagne when he left my battle party for good. LEAVE ME, HAHN, AND DON'T EVA COME BACK!!

Rune is quite the special character, indeed. He holds with him a very special past that will eventually be revealed to you towards the end of the game. You're going to absolutely LUST over Rune and his powerful techniques & magical spells. However, his defense is very low. You might as well equip him with two shields. Rune first joins you pretty early in the game. Then he leaves you! >_< And just when you're about to mail a bomb to the programmers of Phantasy Star 4, Rune eventually rejoins after you go through a couple quests.

Gryz lives to avenge his parents, who were killed when the dark wizard Zio destroyed the village of Molcum. The only other surviving member of his family is his little sister, who remains in the village of Tonoe. Gryz relies on brute strength and his skill with the axe. As you may have already guessed, Gryz joins you when you arrive in Tonoe.

Rika is a biological construction created by Seed, one of the last computers on Motavia. She has spent her whole live in Seed's bio plant. You'll like Rika; she learns some pretty strong healing spells fairly quickly and her psychical attacks are adequately strong.

Demi was created to act as a systems controller for the climate stations built on Motavia. She is the only one who is able to interface with Nurvus, but has been captured by Zio. She just joins you for a short time. Since she is an android, the ways for her to get cured and revived are differently than with humans: she has some self-repair skills for herself, she requires the item "Repair-Kit" in order to be revived during battle, she automatically revives when you win a battle and self-restores 1 HP for each step you take when walking.

Wren is an android and the system controller on the Kuran satellite. He feels a sense of responsibility to the problems going on with the system computers, so he decides to join once you meet him. Because of his android characteristics, it would be best to keep him in front of your battle party to take the majority of damage during battle. Wren is really awesome! He attacks with all sorts of vulcans and laser guns and other things of that nature.

Raja is a sarcastic old priest who protected the Temple near Ryuon until someone had the nerve to land a large spaceship on it. You're going to LOVE him! He's the healer of the game so he learns all of the healing spells the game has to offer. He also spurts out a lot dumb jokes that will make you go -_-;;

Kyra an is an Esper from the Esper Mansion. Ugh, and she sucks big-time! She's weak in every area. I was trying to hold up a crucifix or something to keep her away from me, but it didn't work. The only thing I like about her is that she attacks with the same bladed boomerang as Alys does. Fortunately, she doesn't stay with you for long.
