The only people on board are these friends, the engineer, and the captain. The crew members cannot enter these rooms due to their duties (please assume this).

One day. Everyone was gathered in the ship's lobby. Their expressions varied: despair, anxiety, confusion. And only two... were impatient. So subtle that no one noticed.
With an anxious face, looking as if she might cry at any moment ...Hey... is Kurono... really not alive anymore...? She looked like she didn't want to believe it.
Shina, being a nurse, says sadly ...They've already gone cold... That's why... we have to at least find the culprit...
Then, in a quiet voice We will now begin the discussion regarding the incident. Did anyone see Kurono-san's movements that day, or anyone else acting suspiciously?
