CS Review Time~
[@Zoey White] 
Hello person! You should know how my review system works at this point so I'll get [i]straight[/i] into it.
[sub][b]*[/b].[/sub] I'd like you to glance through your bio and hone down more-so on the Demon Slaying Corps. What drew her to the Breath of Wind style? How did she find out about Muzan? Just some more elaboration on her time-experience on how she got to the point she's at rather than solely on the pre-dark-stuff? Just convey that story a bit more clearly, and I'll give you the big green light.

Hi UwU.
[sub][b]*[/b].[/sub] Another character with a revenge story against the demons, but thank you for explaining the transition of noodle boy to swordsman and as such bio checks out. Blade is unique and fits the thematic, Breath of the Crane is cool and the use seems viable and unique and as such he's solid. Green light to move him over to characters whenever you're ready.

[@SilverPaw]
Ohh, this art looks promising.
[sub][b]*[/b].[/sub] So while the bio checks out and the sheet itself is very detailed and well-written, the only thing that I take issue with is the the use of literal fire in your sword style when the Breath of Flames is already established and kind of embodies something else entirely. So while I'm not outright going to reject your sheet, I'll have you rethink the premise of her sword/combat and make it a little less fantastical.

It's the other saber.
[sub][b]*[/b].[/sub] What a refreshing bio, and it checks out too. Breathing style is unique and viable so it also checks out with a Haru stamp of approval, and the Zenitsu super-hearing is fine as long as you don't abuse it. So you get the green light and can move the character over whenever you're ready.

[@Jacky]
That's an edgy boy.
[sub][b]*[/b].[/sub] Okay, so your bio would check out if not for the quick jump to Pillar without any elaboration of how he came to that point or the root of his swordstyle. You need to kill a Demon Moon or inherit the role from a previous pillar, and that's the only way to get to that role. But the Mountain theme of your style on the other hand isn't explained really well either, so if you could elaborate on what sets it differently from Breath of Stone/Earth because it sounds eerily the same. But other than that, just rethink some of those things and spin him back.
