Good vocabulary and easy to read. Interesting stories too, especially the one with the free spirit and the twisted mage.
I would have liked to see some more description of the main characters. There are only a few tidbits, and it takes quite some time to realize that Kali is a mage, e.g., Taci is female and has a cyberarm, but nothing more and the only thing we know about Zeebo is that he's probably a troll shaman. Even a few throwaway keywords would help greatly with description and characterization.
The same goes for the location. I'm getting the impression from vocabulary, that Kali is located in London or another British sprawl, which would also fit her ethnic background. This is a good thing, because your writing encourages this association, but a confirmation and description of the environment would be equally helpful.
A few typos, but that's to be expected. No one can proofread their own work reliably
All in all I enjoyed the stories with Kali's Darkness being the best.
The snake & the chameleon has a lot of promise but needs a bit of fine tuning, IMO.
Specific comments on writing and spelling below:
Kali's Darkness: BurnoutAres Alpha is an assault rifle, not holstered. Ares Predator?
'I think they were a shaman?' -> deliberate gender neutral singular they to emphasize the anonymity or a mistake?
Kinezumi's Past:'energy drink' needs to be plural
Taci's reaction to Amarantha's story is first 'stunned' then immediately followed by a huge grin. I don't know anyone who'd react that way to a story about forced prostitution and becoming a hired killer.
The snake & the chameleonPart 1: 'taped his horn' -> tapped?
Part 3: states that Zeebo is an ork, despite the horn he tapped? Did you mean the horn of the car? If so, a small description of the sound would be helpful in part 1.
Part 3: 'singlespider plant' -> space needed
Fernando is misspelled a few times, Fernado, Ferando. Mostly in the part where he interacts with Mr. Yama.
Rules & Fluff: Zeebo repeatedly assenses 'Fernando', but only 1 success is necessary to see if a person is awakened, while 2 are necessary to recognize an aura you have seen before. If you stay close to the rules, he would have immediately realized that 'Fernando' was magically active. If Fernando were an initiate with masking, Zeebo would need to be an initiate, too to break through the mask and he would realize that the mask was present.
Part 3 makes it seem as if Gabi is very inexperienced so having her be an initiate could be weird, but spontaneous self initiation is always a possibility, especially exhibiting the masking metamagical technique as a chameleon.
If the story is located in Chicago, it should be described more closely. Chi-Town is a feral city and the ambiance is very important there and could enhance the story.
Zeebo stating that he sicced a watcher on Fernando after the 2nd scam should be mentioned in the first part of the story, especially since he hadn't decided at this point to catch the scammer.
The blackmail seems unmotivated, especially after Snake having told Zeebo that Fernando will help him in the future ... Starting a relationship on blackmail doesn't usually engender trust or positive feelings and the trust dynamic between the blackmailer ('She could easily call the cops on him') and the blackmailed allowing him to cast spells on her seems off for that reason.
Zeebo also has a very patronizing tone towards her.
It is not explained why Gabi would go to college in an alternate identity.
Rules & Fluff: In part 2, Zeebo summons a spirit to open an astral gateway. He uses it to enter the apartment, but a) only free or great form (guidance) spirits get the astral gateway power and b) astral gateways don't work that way in the rules (or more precisely, astral rifts don't). The workings are a matter of interpretation, but it seems like Zeebo physically entered her apartment through the rift. If he just projected, he could easily just manifest without the need for an astral gateway at all, although Gabi would be unable to see the astral space.
Astral activities are also very dangerous in Chicago, due to lingering FAB-III bacteria strains and resulting mana ebbs often make it difficult.
