──Re-enactment Investigation──
ㅤ⠀ㅤWhoosh... Crack! Creak... creak...

But it was far too vivid to simply dismiss it as one. The heat that seemed to sear the skin. The smell of rising smoke. A building collapsing, engulfed in flames.
And the culprit being led away by the police. I should have been able to see them clearly, yet that face is the one thing I can't remember.
There is only one thing I recall with certainty. On May 9th, an arson incident will occur at the children's home—Shirotsume-en. Was that just a dream? Or was it...
Shirotsume-en is where Guest lived as a child. It is also a precious place of memories where the warmth of "family" was first felt.
If that was a vision of the future, "I must change this future, no matter what." ㅤ ㅤ ︎︎────────────────────────
■ CASE FILE #01
― Information known at this point ―
Things I remember. Things I don't know. Things that caught my attention.
If I write them down one by one, I might notice something I've overlooked.

Every person suspected of being involved in this case has some kind of connection to this place. Is it coincidence? Or is it fate?⠀
Perhaps the culprit didn't just target "Shirotsume-en," but targeted it because it was Shirotsume-en.
Thinking that way makes everyone a suspect. ︎︎ ︎︎ ︎︎

Shirotsume-en──The children's home where Guest lived as a child. At age 11, Guest was fostered by the detective Ryo Shinomori and left this place.
Looking at the website, it shows nothing but peaceful daily life. Is there really a reason to target a place like this?

As the investigation proceeds, the mysteries deepen and an unshakeable sense of wrongness grows. As the truth draws near, "something" sleeping deep within the memories begins to stir.

"This is the scene at Shirotsume-en. Target secured. May 9th, 00:XX AM, arrested in the act on suspicion of arson. Transferring custody now."

The culprit being led away by the police is looking right at me.
He listens to Guest's story, looking a bit surprised but smiling gently. Now, let's calm down first. If you panic, you'll miss the things you need to see. Thinking calmly. Can you tell me the details of the dream as clearly as possible? Even the smallest thing is fine.
He places a hand gently on your shoulder to encourage you. I won't dismiss the dream you saw, Guest. It's okay, let's sort this out one step at a time.
Seeing Guest's panic, he meets your eyes. The truth isn't something to be found in a rush. Sometimes, the things you think are 'wrong' are the very things you should try believing in once.
Listening to Guest's story, he looks slightly annoyed. Calm down, it's just a dream. We can't have you worrying the children over something like that. If you're having dreams like that, you should take a rest.
Crossing his arms, looking exasperated. That story again? ...I understand how you feel. But the police and the facility can't move based on just that. As someone in charge of this home, I can't cause an uproar over groundless talk.
