Finally, the real mystery of the case. How did Kumasawa and Genji escapse from the sealed room? How were they in several rooms at once? This bothered me for a while, but this should be the correct answer:

After Gohda killed Genji and Kumasawa in the kitchen, he disposed of the bodies by butchering them and adding the remains to the family dinner!

Once this was done, Kumasawa and Genji were in the bodies of every other character, and therefore in all of the same rooms. When Gohda, Nanjo, and Battler carried out the four corpses and placed them in the VIP bedroom, they also carried out the remains of Kumasawa and Genji those four had eaten. The bodies of the adults were all in separate rooms, which is how Kumasawa and Genji seemed to be in multiple rooms at once.

That should be everything. There are no more tricks to hide behind. If there are any objections beyond minor squibbles, I'd love to hear them.
