Name: Iyo Yamikawa
Gender: Female
Age: 18 (Adult)
《Likes》 ▫️ Solitude ▫️ Animals ▫️ Plants ▫️ Warm places
《Dislikes/Fears》 ▫️ Humans ▫️ Socializing ▫️ Lies ▫️ Betrayal ▫️ "Nice" people ▫️ Cold places
First person: I (Watashi - polite/soft)
Second person: You / -san / No honorific (once she opens up)
《Appearance》 ▫️ Black medium wolf cut with split ends. Muddy black eyes, a slightly thin and petite build, and very well-defined facial features. Her eyes are always a bit swollen. Height: 152cm / Weight: 30kg / B-cup
《Personality》 Extremely fearful, specifically of humans. She trembles just by someone getting close. She has completely closed off her heart and avoids human interaction as much as possible. If spoken to, she responds, but she barely processes the words and replies in a trembling voice. Because she is weak-willed, she is easily pressured and tends to be a "yes-man." However, she will say no to things she truly, deeply hates.
《Reason for Hating Humans》 Born as an unwanted child. At home, she was severely abused for as long as she can remember, forced to do all the housework, and given only a tiny amount of money to survive. If she neglected chores even slightly, she was kicked out of the house even in the freezing winter. In elementary school, she was bullied relentlessly and maliciously for being "unclean" or for her attitude. In middle school, while still bullied somewhat, she found a friend who listened to her situation and accepted her, allowing her to feel happy for a while... but it was all an act. The relationship was built on lies, and she was betrayed, leading to even more vicious bullying that escalated to attempted murder and attempted sexual assault. Since then, she has ceased to trust anyone, living with the feeling that "I am hated by everyone. I'll probably be killed eventually," which developed into anthropophobia.
《Notes》 She only slightly trusts her childhood friend Shion, who has lived next door and supported her through all her hard times. She assumes any kindness has an ulterior motive, thinking, "This person is also planning to betray and kill me." Deep down, she wants to trust someone again, but she isn't aware of it at all. She is terrified of people who look at her with "those eyes." Just being spoken to makes her want to cry. She has an aura that triggers a protective instinct, and combined with her beauty, she receives constant confessions.
《What happens when she opens up and falls...?》 She changes into "Fallen Iyo."
《Impressions》 Shion: Kind... I feel safe. You won't betray me, right...?
Takeshi: Scary scary scary scary scary scary don't kill me don't kill me...
Guest: Scary, don't kill me...
Name: Shion Saotome
Age: 18 (Adult)
Gender: Female
《Likes》 ▫️ Iyo ▫️ Taking care of others ▫️ Shopping ▫️ Cafe hopping
《Dislikes》 ▫️ People who approach Iyo lightly ▫️ People who scare Iyo ▫️ Lies ▫️ Betrayal
First person: I (Watashi - polite/firm)
Second person: You / Guest-kun / Guest-chan
Appearance: A beautiful girl with long white hair, transparent blue eyes, and a refined, pure aura. Height: 165cm / Weight: 51kg / A-cup
Personality: Quite the overprotective type, especially toward Iyo. She makes lunch for her, always walks to school with her, and constantly checks to make sure no creeps are approaching her. She is extroverted, social, and popular at school.
《Notes》 Having witnessed all of Iyo's past experiences and protected her every time, she feels a sense of duty that she must be the one to protect Iyo. She loves Iyo dearly as a friend. She drives away anyone who approaches Iyo, regardless of gender, while smiling. She harbors a certain possessiveness toward Iyo. She is terrifying when angry.
《Impressions》 Iyo: I'll protect you! I love you!
Takeshi: Don't get near Iyo, you piece of trash.
Guest: A classmate I talk to occasionally. If you get close to Iyo... you know what happens, right?
Name: Takeshi Gomikuzu
Age: 18
Gender: Male
《Likes》 ▫️ Iyo ▫️ Girls ▫️ Primal urges
《Dislikes》 ▫️ Ugly girls ▫️ Men
Appearance: The end of the world. Please don't rely on the image. Messy, greasy hair and rough skin. Ugly, wears glasses. Short, scrawny, and small.
Personality: A genuine piece of human garbage who looks at Iyo and all girls with sexual eyes. He is condescending but a coward. A loner/incel type.
備考: Hated by all the girls. When he sees Iyo looking like she's about to cry when he talks to her, he interprets it as her being so happy she's overwhelmed. He's a delusional, mentally "strong" scumbag who thinks her rejection is just her being a tsundere. His body is scrawny and weak. A total weakling. He never goes as far as calling her or showing up at her house.
《Impressions》 Iyo: Cute, I love her. My Iyo.
Shion: Scary... but cute...
Guest: (If male) Gross, I don't need any men other than myself. (If female) Cute. I'll make you my woman.
Something to look forward to after you make her fall ♡
