Appearance
. has black hair that covers part of her eyes but doesn't go far past her neck. She wears predominantly black clothes, and only shows skin on her face, which appears grey in game, though it should be noted that her skin is beige in a drawing made by Calamituff. She wears a black long sleeve sweater with black gloves, a black skirt and short black boots. Her tights are horizontally striped black and white. Her eyes are pitch black with no white. In Version 1, she appears rather different, as a grey sillhouette with long, black hair and hard to see details.

Personality
When you first play as. in Version 2, she's quiet, afraid, and has long pauses between words. As the game progresses, you start to see more of her personality, she's kind and thoughtful towards others, and seems very hopeful about the situations she gets in, always trying to reassure people that it'll be okay. She's prone to breakdowns and falling unconscious, as seen in Chapter 2, and again in the ending of Chapter 3. These seem to be caused by hallucinations and the embodiment of .'s negative emotion, Bloodshot D.

E
. and E appear to be very close, as. attempts to get over trauma from E's suicide throughout the game, and often hallucinates about her. In Chapter 3, E's spirit is the boss, seemingly gone mad due to Bloodshot E being given control over her. She tries to kill. so that she can join her in the afterlife, but gets defeated and returns to her senses. The two get incredibly emotional over what happened to E, each blaming themselves, before settling down as E promises to redeem herself to ., while. feels as though she doesn't have to. They're mentioned to have been like sisters to one another. In the true ending of the game, E leaves. as she belongs with the other spirits, and they share an emotional goodbye.

C
At the good end of Chapter 2,. and Hiveling end up at C's house. C is surprised by the intruders, but lets them stay under her roof as long as they follow her rules. As Chapter 3 progresses, C's cold personality begins to get swept aside, and eventually C tells. about Ellie on the balcony. . comforts C as usual, and C shows that she cares about. and doesn't want her to end up like Ellie. After beating the final boss in Chapter 4, C continues with her plans to have. and Hiveling live with her.

Hiveling
Hiveling is the first interaction with another person. has in the game, and immediately she joins the party due to .'s sympathy. Hiveling later frees. from Left and Right's grasp, going against her hivemind. During Chapter 2,. and Hiveling strengthen their bond as the only company for one another as. leads the way into The Tree. After the final chase against multiple of THEM, Hiveling loses it and starts to panic about their seemingly inevitable demise. . fails to calm her down, instead hallucinating E, which causes her to breakdown and pass out, leaving Hiveling alone. Hiveling immediately regrets what she did, and carries. around with her, looking for safety. To Hiveling's relief,. regains consciousness at the end of Chapter 2. In Chapter 4, Hiveling feels bad again and needs reminded of her importance by ., who brightens her mood. The two are living together with C in the Good Ending.

Kamia
Kamia's first course of action upon meeting. is to attempt to kill her. When defeated, she regains her cool and allows. to hang out with the hive before departing. The two appear to be on good terms despite the attempted murder.

Stripes
Stripes hates all 3 party members in Chapter 3, despite .'s attempts to reason, thinking that they're defending THEM by not letting the spirits take vengeance. . calls back to Stripes during the ending.

Bloodshot D
Bloodshot D is an embodiment of every negative emotion. feels along with her mental state. . tries to reason with Bloodshot D about why her life is worth living, but even by the end of the game, Bloodshot D isn't fully convinced. In Chapter 4's ending, Bloodshot D is still a part of. and no real solution is found, resulting in a bittersweet conclusion. It's likely this way because the story isn't over yet.
