One cliché after another...
First of all, I deducted three points from 'Graphics' because you tend to use the Japanese style of animation. Use your own.
Second, this is just terrible.
The story is leading toward a road congested with traffic. Everyone takes that route; that highway.
Action is needed, not just talk of it.
"I was trained in martial arts and weapons combat." So what? and for what?
The characters are just puppets used in a plot unsurrounded by a story. There is lack of almost everything essential to make this entertaining. The chacarters have not gone through "deep" tragedy for us to feel sorrow, and they are not doing much "good" to grasp our attention.
Concern yourself with the base of a story. Do not make this a long story told through magnificent anime-style art. Concern yourself with the needs and wants of the characters; let us feel and understand what THEY need. Currently, life is meaningless to them, but what made that? And why don't they make a difference?
Also, keep love aside; it's the downfall of every hero (and vilain). One woman is all that matters, and she is needed only at the end (if needed at all).
Last, do not give the characters super powers. Fireballs, gravity attacks, water elementals... Not needed. Just make them better human beings. As best as they can get without actually being human.
Keep all those points in mind and remember, a plot is useless without a story surrounding, and directing it.
