Vivo:

Personality: It would be nice to know a little more about how he thinks/reacts internally to things. Right now he's mostly written about how Vivo doesn't like to talk or interact with people, which is fine, but doesn't give me a great picture of who he really is beyond that.

Fighting style: Feels contradictory, but it may just need more detail. It's totally attack focused with absolutely no defense, but he still dodges and deflects? Also, no mention of how he uses the katana in it despite it being his main weapon. Strange that an all head on attack style has exclusively projectile techniques.

Formatting and spelling/grammar: Remove DF info, remove information in parenthesis, things like “eye site.” Inconsistency with names.

“ this can cause people to lose their feet… I mean footing  “ I'd like him to lose this joke, it makes the description more confusing than it needs to be.

 Bestiale Mezza Spada: A little confusing. How many times is he swinging his sword? I assumed an air slash technique more or less required the swordsman to swing their sword, but the description implies he follows it up with a “real” slash. The technique itself is probably fine either way but I feel clarification is needed.

Bestiale Sotanto : Where is he aiming this? The description implies upward to “split the very sky” (which I'm assuming is just poetic license),  but apparently it “veers off” toward the sky after a few seconds. Again, his intent is probably fine, but I'm very confused by the description.

His katana is listed as a normal weapon, but his history implies it's more durable than a run of the mill katana. “his father even made him his first sword. The only sword he always returns to using after his Marine standard one keeps breaking due to his insane style of fighting. “ Probably not important since no one's going to be policing when/if his sword breaks during normal use. Something to maybe keep in mind though.

I don't really understand why Dan was killed. Apparently to get to Vivo, but there's nothing to indicate that Vivo knew that it was a frame job. Maybe if someone somehow made it clear that it was a warning to him? I would also like to know why the marines are all so against Vivo; it kind of sounds like they were just jealous of him for being really good at his job, which I don't buy. It leans a little too heavily on “The Marines/WG are actually evil!” to have them ruin a promising soldier for no reason. If he was working to root out corruption, or if he established a rival who was working against him it'd make more sense.

Minor, but I'd like to know Vivo's rank when he was discharged from the Marines. I don't believe it's mentioned.
