Girl

Girl (default name) is the main character and protagonist of Cat in the Box. She is an aspiring Youtuber and, at the beginning of the game, intends to explore the Mansion in hopes of posting her experience on social media for it to go viral. The player may name the protagonist themselves, however Girl is what is entered by default.

Appearance
Girl has upper back length, blonde hair partially tied back and a chin length fringe parted in the middle to frame her face. She wears a gray zipper hoodie with a long-sleeved black shirt underneath and jeans. Later in the game she can be seen in the mirror to have developed dark circles under her eyes.

Story
Girl is an upcoming paranormal Youtuber, who seeks out haunted places and vlogs her exploration of them. In the latest of many attempts to go viral, she, with the help of her sister, pulls together the resources to visit an abandoned Mansion that recently housed a cult that inexplicably disappeared recently. She enters the Mansion claiming it is far different from the others she has visited in the past.

While roaming the Mansion, she encounters a figure covered in a bag, who attempts to chase and kill her. Girl runs away and finds a hiding spot in a dark room behind some boxes. The killer nearly finds her, but hears the sound of a door opening elsewhere and leaves. After waiting for a moment, Girl feels it safe to come out. She finds that her phone, if she had it to begin with, is missing and that she must have dropped it while running away. She decides to leave the Mansion and regroup. However, the way she came in no longer leads outside, but to yet another room in the Mansion. There, the Stranger introduces herself from behind the door, asks for chocolate, and reveals that they are both trapped inside the Mansion. In order to escape, the Stranger guides Girl on what to do: exploring, turning on a generator, gathering Ritual ingredients, and more—all while keeping her appearance and identity a secret.

Deceive ending
Girl complies with the Stranger's instructions and cuts off her finger for the Ritual. However, as she is chanting, the Stranger quickly leaves, leaving Girl behind. After the Ritual ends, Girl finds that the room is now completely empty and the Stranger nowhere to be seen. Annoyed, she goes to leave the Mansion. As she enters the entrance room, she finds a series of memos left behind by the Stranger and a camcorder tape, revealing that there has been a 'break in the space-time continuum' and that 'only one may leave'. Realizing what this must mean, Girl frantically goes back and forth around where the exit is supposed to be, calling out for the Stanger. She stands in the room left of the entrance, completely at a loss for what to do, when she hears the sound of a door opening. The credits roll.

Epitaph ending
If Girl fights off the Stranger and chooses to sacrifice someone else's finger, she will seemingly successfully leave the Mansion. At first, it appears that she is back at home with her sister, the events of the game seeming to have not even taken place. However, as she goes to sit at the dining table, a statue from the Mansion seems to watch over her, as the cutscene is revealed to be a dream. In reality, Girl runs off the cliff shown at the beginning of the game, with many bodies - all being her own - surrounding her.

Divine ending
If Girl fights off the Stranger and uses her own finger, the Ritual will succeed and she will be able to leave the Mansion. The final cutscene shows Girl in the hospital, with her sister visiting her. After her sister leaves, lightning strikes and tentacles appear, showing that while she may have escaped, she may have also released the being trapped in the Mansion into the world.
