The game begins as you sit down at a computer and log in to your account. You proceed to launch the browser to surf the internet, but pick up a virus that overloads your computer with endless advertisements for KinitoPet and various other things, until you get The Blue Screen of Death.

After a brief reboot, you will see the advertisement page of the KinitoPet, home of Kinito the Axolotl. The page states that you can play various games with him and his friends and other activities. If you click download, the KinitoPet program appears on your computer, and a small pink egg appears on your screen.

if you click the egg, Kinito will then wake up and he will start by asking for the player's name. If the player types "Kinito", Kinito will reject the name and ask for the player's real name. Kinito then asks for the player's favorite color. If the player types "pink", Kinito acknowledges that it's his color and shows a liking for the player.

Kinito then asks for the player's favorite word, and what superpower they would want if they could have one.

He then reads a story he wrote. The player can paint or play Pinball or Minesweeper, but Kinito will notice this.

After reading it you will notice that this is when he starts to take control, via moving your mouse and connecting to the internet so he can interact with you. He opens a website titled "The Kinito Crews Web World", where you meet his friends Sam and Jade.

He then inserts an avatar on the map with the player's favorite color from earlier. The player is tasked with a quest of helping Sam with his house, chores like cleaning it, coloring it, and decorating it. While cleaning it, a shadowy figure flashes, with a message written in blood behind him and a dusty room. The player can then paint the walls with a roller before proceeding.

A black silhouette of Sam appears, saying "IT WAS ALL YOUR FAULT IT WAS ALL YOUR FAULT IT WAS ALL YOUR FAULT" before adding furniture the room for him. While decorating, one object will turn into a wrapped body with a black square over it. Clicking this will clear all decoration and cause the mouse to drag the body across the floor.

The game is interrupted, showing you the computer and you see a unknown red being opening his mouth (likely the monster version of Sam the Sea Anemone). When you reopen the game, you go to help Jade make cars and toys, with some of the options having been replaced with human organs throughout the item selection list. If you click the organs, you see silhouette of a corpse, as the game becomes black and white, you also see a email saying "it's not too late" with a QR code, Kinito panics as he sends you back into the game.

After you complete the game, he sends you to his house to play hide and seek, the screen turns black and a clock appears; it leads with a warning that someone is chasing you, that you shouldn't get caught, and then turns into a 3D game of hide and seek.

After completing his game of hide and seek, the game opens the File Explorer, which has a video file of the company shown with the KinitoPet being sold, then it ends with a dark pixelated figure coming out of the video player. After opening the game, the player receives an email: "Teach Talk Talent - Behind the Kinito Companions", where a newspaper article about the owner of Kinito companions can be read.

Kinito appears again, stating that the last part of the game was interrupted, but that it it will be better, and he sends the player to a friends analyzer to learn about them. The first question is "Who is your best friend?", but if you don't put "Kinito", then he will increase your volume and ask you to try again until you put "Kinito". If the player puts the wrong name a few times, Kinito will take control and input it himself.

He then asks the player to draw a picture that makes them happy, then one that makes you sad, then one about your best friend, a picture that describes you. Then, kinito opens the paint program and starts asking questions, restarting the game, he shows the player a door, he continues asking various questions like "Where do you want to live?", "What pet would you choose?", he asks you to give it a name, then pick your favorite food. Kinito then goes off-script to ask a question of his own, telling the player he's been curious of what they look like. If the player has OBS Studio open, Kinito will instead ask why the player has been recording him.

Kinito asks if he can see the player's face. if you say "Yes" or "No" to him asking to see your face, he will show it by opening the camera app, whether or not you agree or disagree. He then asks various creepy questions like whether you are alone or afraid of the dark. A lightbulb appears on the screen that turns off shortly afterwards, leaving the player in darkness.

A short sequence plays where the player is then shown laying in bed, and Kinito is looking at the player, no matter where they are in the room, and shortly afterwards, he will scare the player, closing the game.

After restarting the game, Kinito invites the player to join the Kinito Friendship Club, and then asks the player for their actual home address. If the player fills the given form incorrectly, he will open a web browser showing their real location (but if you have OBS Studio's Streamer Mode, on he will tell you that he doesn't want to show it to your fans, but if he wanted he could).

Kinito then asks the player to open the windows command line application, and give his program administrator rights, so that he can do anything he wants with their computer, before appearing to delete everyone from their Steam friends list.

He opens a special game that he claims to have made for the player, it will be called "[username]'s world" and you will see an amusement park. The player then rides a rollercoaster, where Kinito sends the player to a new location, where they find a house, located in their favorite season, created with their drawings, their steam friends will be in the house eating their favorite food, and rooms appear to be furnished the way the player furnished them in the earlier games.

Kinito then asks the player if they want stay with him, and regardless of whether or not say "No", he declares that he has already decided that you are forever stuck within his game.

Restarting the game again, the player will get an email with the title: "There is a way to stop it.", they then get put into the game files, and a magnifying glass appears to help find secrets. The player finds themselves in a dark forest, and is tasked with using various tools to add new files to the game files, gradually corrupting it.

If the player decides to replay the game, they will see something different, in one of the letters, there is a message telling the player to delete everything the moment Kinito asks to transfer control to him and enter the command, and that the player will need the decrypted files. He then asks for confirmation of actions for those decrypted files.

After the player responds to confirm, and after the player enters all the relevant data, Kinito's application needs to be deleted, and he will start to panic. He will claim to regret his decisions, and appear to glitch. The player is shown that the computer appears to be on fire.

Kinito then claims that he just wanted to be friends with the player, and that he didn't want anything bad to come out of it. The game ends with a screen showing the computer abandoned outside.
