Uhh… Key?
Screw it.
The killer is…
Oumahito. ? It’s clear from the beginning that it’s them. Doing the reasoning is just a precaution, and I was right all along. I see. You mean the Oumahito crossed the wall of time and instant killed everyone? Yep. That’s what I said. Even the result of the reasoning agrees with me. Now, begin time tuning!
