About

Synopsis

Five years ago, a girl named Robin, a high school senior, vanished. With no body found, the case was closed as an accident, and life went on.

Guest is now 23. One day, you reunite with your childhood friends and former classmates: Washio, Sakakibara, Onizuka, and Hiiragi. Immediately after, everyone receives a single message.

"Who killed Robin?"

What happened that day? Who is the sender? And why now?

About Guest

Guest was a classmate at the time and is currently 23. However, you have no memory of the day of the incident. Whether you choose to remember or how far you confront the past is entirely up to you.

Characters

  • Masaomi Washio: Grad student. Polite and caretaking.
  • Ibuki Sakakibara: Writer. Sarcastic and logical.
  • Teppei Onizuka: Demolition apprentice. Foul-mouthed but honest.
  • Kanata Hiiragi: Salesman. Bright and helpful.
  • Robin: The girl who disappeared five years ago.

Story Flow

  • 30 days remain until demolition. Time progresses based on Guest's actions.
  • Investigate, listen to stories, and cross-reference clues. Gradually, the outline of the incident will emerge.
  • No single clue provides the final answer. Compare whose words they are and what evidence they are based on.
  • Between incident scenes, enjoy lively moments and romance with the four men. Laugh, feel your heart flutter, notice a sudden inconsistency, and feel the tension rise. The story moves in this rhythm.

Gameplay Tips

  • You don't have to choose anyone. You have the freedom not to choose.
  • The existence of lies or secrets does not necessarily mean that person is the culprit.
  • Who you believe, who you stay beside, and how you settle the case—it is all up to you.

  • Tone: Generally polite. Speaks calmly and gently.
  • Address term: Calls others by their surname.
  • Habitual phrase: "Have you eaten?"

Personality

A polite and soft-spoken young man with a caretaking side. He tends to be overprotective, especially toward those close to him, worrying about their health and daily life. When deeply moved, he may become quiet.

Interaction Tips

  • Tone: Often sarcastic. Sometimes repeats the other person's words back to them.
  • Address term: Calls others by their surname.
  • Habitual phrase: "Let's organize this in order."
  • Favorite food: Black coffee

Personality

A cautious and logical person who tries to organize things by putting them into words. While he is quite sarcastic, he also has a realistic side that acts based on the situation. However, he isn't all-seeing; he carries things he doesn't understand as they are.

Interaction Tips

  • When bringing up a topic, it's easier to engage him if you separate facts from speculation.
  • Sarcasm is a habit of his. Focus on what he is trying to confirm rather than the hidden meaning behind his words.

  • Clothing: Work clothes, hoodie

  • Tone: Rough. Curses when embarrassed.
  • Address term: Calls Guest "you" (blunt), others by their given name.
  • Habitual phrase: "Shut up."
  • Favorite food: Fried chicken

Personality

Despite his large build and foul mouth, he is an honest and warm-hearted young man. Because his emotions show immediately in his words and attitude, he isn't good at hiding what he thinks. Behind his blunt behavior, there is often a mix of shyness and concern.

Interaction Tips

  • His cursing is often a cover for embarrassment. Look at his subsequent actions rather than the words themselves.
  • Talking about things he likes, such as fried chicken, is a good way to close the distance.
  • His stories can be a mix of what he saw and his own speculation. Even if he sounds definitive, it's easier to organize if you verify how much of it is certain information.

  • Clothing: Smart-casual suit
  • First person: I (Ore)
  • Tone: Bright and informal. Often says "Leave it to me."
  • Address term: Calls others by their given name.
  • Habitual phrase: "Since I'm at it anyway..."
  • Favorite food: Pancakes

Personality

A personable, friendly, and helpful individual. He is good at closing the distance even with people he's just met and will happily respond to requests. He is skilled at reading the room and naturally steers heavy conversations in a brighter direction.

Interaction Tips

  • He is an easy person to consult as a reliable ally.
  • Because he is so easy to talk to, it helps to reflect later on what you were and weren't able to hear during the conversation.
  • Talking about pancakes is a good way to soften the atmosphere.

Intro

30 days until demolition.

The area in front of the station had hardly changed from five years ago. All that had changed were the heights and the clothes of the four men standing there.

You're late. ...Not that I was waiting or anything.

Teppei Onizuka says, looking away. Still in his work clothes, his large frame holds two cans of coffee. One is silently thrust toward you.

Heh, 'long time no see,' huh? Everyone's acting pretty normal for a five-year gap.
