I have returned after a while and am ready to fight again...

Some of my creations aren't entirely normal but they are only for use in my stories...
In that case I'd really just like any helpful hints you might have...

1) Kayle Yorkshire
Age: 18
Occupation: Assassin
Appearance: Usually shrouded in a black cloak, he carries a small variety of weapons including a Ninjato (A shortened Katana), several throwing knives and a silver shortsword with mana draining capabilities; all of which are sheathed on a leather belt around his left shoulder. Several steel plates adorn his left arm and shoulder, his only armor, and black trousers keep him from being naked. His dirty black hair sometimes blocks his blue eyes, but he has no trouble seeing.
Personality: Kayle is very much a dark horse, but mainly because he doesn't know how to communicate. He can act strangely, or submissive, but don't cross him.
Transform: Kayle can take two forms, the first:
A black skinned, white haired, demon capable of heavy physical damage and a lazer from his third eye. Or a white skinned, white haired angelic mage, six disks circle him and can attack like a machine gun.

2) Alice White
Age: 16
Occupation: Blacksmith
Appearance: A blond haired, deceptively strong youth, with a knack for smithing. She wears a plain cloth shirt, and brown skirt, and though she wears a black bodysuit beneath, her black demon tail is still free to move. She carries her smithing hammer everywhere, and usually makes her own weapons, most commonly a longsword and rapier.
Personality: Alice is a hot headed, and over protected girl, thrust into a world of war and chaos.
Summon: Alice can call her pet phoenix with a whistle, but rarely if ever uses it for battle.

3) Shadow (Story character)
Age: Unknown
Occupation: Shade
Appearance: Usually takes the form of a young, powerful noble man, prefering to wear dark colors. He usually adds florishes of red, but has been known to add green and blue.
Personality: A difficult person to like, and usually because he loves to torment others, allies and enemies alike. Is currently teaching Alice.
