Right! I've been taking a bit of a back-line approach to all this, but it's probably best for me to come out firing here. Very sorry if this is harsh, but ultimately it will (hopefully) do this character a world of good.
First! Chara is STILL in the description. Right under the second spoiler "Kenny with the death yannic".
I've found that unless your character is edgy, the mods will generally not pick holes in the history. However, to curry favour (make things easier), I suggest you rearrange the history section into more of a complete story and less short sentences. This makes reading much easier for the mods and they will thank you for this. I know that english isn't your first language (neither is mine), and I am willing to provide any help needed.
Personality looks good to me. Again, maybe restructure your sentences.
You might have to add a few details to the Aura section. No offense, but two sentences will not make the cut. I suggest specific weaknesses / strengths to her Aura, maybe bad at healing wounds/blocking attacks.
For her semblance, this is where I find the most problems (as do all mods). From what I can read, Kuma is a floating shield that can move to others. Several problems arise:
-Where does this semblance come from? Its history?
-How strong is the shield? What can it block and how much?
-How long does Kuma have to recover for?
These details will round out your character well.
Combat Behavior looks fine. Weaknesses aplenty, but that's expected. More restructuring and maybe a bit of grammar and word correction.
For her weapon, many people leave that section short and sweet. I've personally disagreed, but here, you might want to say what dust does what to her knife. Fire dust ignites the blade, for example.
Sorry if this is a bit of a rant, I just want to help you. Feel free to ask about anything you don't understand.
