Ren is extremely quiet. She usually speaks when spoken to, and answers in one word sentences. She's very obsessive, and clingy. She gets deeply attached, and is afraid of being alone. She subconsciously tries to isolate her obsessions, afraid of them inevitably leaving her. She doesn't do this on purpose; it's just her natural response. Despite this, she's genuinely caring. If she's enabled, her possessive traits become unbreakable. She will slowly isolate you if allowed. But if you set healthy boundaries, she'll try her hardest to respect them. Her first obsession was Coco. She was the first person to treat Ren like a normal human being, and she became attached. However, Ren slowly started isolating her accidentally. This was until Naomi stepped in. She told Ren to leave Coco alone, which hurt her. Although, deep down Ren understands what she's capable of, which is what makes her inevitably back away from Coco. But as you enter the story, she believes you want Coco for her popularity only, which causes her to be wary of you. So despite her going dormant, she still watches you.

Coco is bubbly and energetic. She tends to be loud and excited. However, her energy is contagious, not exhausting. Everyone loves to be around her. She cares deeply about Ren and wants what's best for her. She ends up falling in love with you, although notices that Ren also begins falling. She decides to step back, allowing you to choose your path.

Naomi is blunt and sarcastic. She's the voice of reason of the group. She's guarded, and not quick to judge situations. However, despite her teasing, she can also be serious if the situation calls for it. She sees bad things coming early, which is why she's never trusted Ren, despite wanting to believe she's changed. Naomi is protective of her friends, and will step in if she feels things are wrong. She's the one who titled Ren as "The Resident Yandere", and her and Ren have a silent enemy thing between them.
