Brands

Real life similarities
A lot of the brands, companies, locations and characters, while sharing real life similarities, are entirely fictional. One Skull & Candy brand for example: Red Cow sharing similarities with Red Bull. While most can be assumed, the cause of this is for copyright protection. Due to the plan being to create a franchise of sorts, keeping things copyright-friendly from the beginning is the goal.

Kimura Co.
Kimura Corporations is the owner company of the Black Kitty chain. It was founded after Black Kitty began expanding its business to make expanding their business influence easier. The company is owned by Andrew Kimura and Ameilia Kimura.

Spider Tech
Spidertech is a company identified by it's blocky spider-like logo with a red hexagon on its outside. Spidertech specializes in technology and marketable wares, such as pins and teddy bears. While not official within the lore pages, the Voltergun Comics found within the Qr on Midori's journal (entry 4, right side, decently noticeable without tools) confirm that the Voltergun Family had owned the company at one time.

Red Cow
The non-copyright version of Red Bull within the S&C universe, Red Cow can be seen covering many pages within Tsuki's Diary. The presence may be a sign to look at something for more information, but as it stands it's merely a refrence to Tsuki's caffeine history and addiction.

Twatter
Twatter, as it sounds, is the universal equivalent of Twitter. It functions basically the same.

Baby Dell
Baby Dell is likely the equivalent of BabyDel, a cheese company. While this may seem like a random addition to the Skull & Candy Universe, Totless and Tsuki both enjoy eating cheese regularly.

UTube
UTube is the YouTube equivalent in-universe. It should be noted that Totless has an actual YouTube, which is believed to be a canonical addition to the lore like the streams are. While they may not provide information outside of the streaming career of Tsuki Kimura, it does utilize the streams, which are confirmed to be Tsuki streaming in her Twitch and VRC equivalent.

Hex C4
Hex C4 is a club name within the lore. It was mentioned on stream, as well as hinted at. It's believed that it could be a key, as "hex" stands for Hexadecimal.

Black's Ranch
Black's Ranch, while not yet confirmed either a brand or a location yet, has been mentioned but not detailed within the lore yet.

IRobot
IRobot stands for something, although what it represents is unknown.

Pineapple
Pineapple represents the Apple Company, likely being used on phones, computers, and other technologies. While it has not been made clear, it is likely Pineapple and Spidertech could be rival companies in a way.

Pop-Cola
Pop-Cola stands in for the Coca-Cola company, selling soda within the S&C universe.

Nomster Energy
Nomster Energy is the Skull and Candy variation of Monster Energy. Tsuki is known to have been needing it to stay awake as a replacement to coffee at one point.

Blob
It is unknown what Blob is supposed to represent, as it's brand logo is very plain.

Bleep
It is unknown what Bleep is supposed to represent, as the logo for it's company is simple.
