If you want to go out, you will also go out from sp.
Tsuda's disappearance (that is, the person in Class 0 of the Metropolitan Police Department mentioned by lz) should be the explanation of the doubt in the conclusion.
In the ending, the key to killing the underground house is the person who can stop time (because time has stopped, this person can make the bullets return to the shooter's position like eleven pairs of bullets). Eleven died, and Diju himself said that he didn't do it. So who is the new ability? Who helped kill Diju?
At the end of the ending, Tsuda (that is, the people in Class 0 of the Metropolitan Police Department mentioned by lz) showed the same external performance as the eleventh stop time ability (for details of the external performance of the eleventh stop time ability, we can see that the eleventh stop time ability disappeared after feeding the kitten, and we can also see that Tsuda suddenly disappeared after taking the kitten away).
It can be understood that Tsuda is the person who helped kill Diju.
(Of course, some people suspect that Tsuda was shown as Tsuda in Class 0 of the Metropolitan Police Department after plastic surgery on1/month1day. This conclusion can be inferred from the ability of those who have the ability in front, but there is no evidence. For example, Tsuda loves to feed cats and eat octopus balls, but Tsuda has not made any evidence that can make people suspect that it is 1 1 month/1day. In the absence of conclusive evidence, I think this kind of reasoning is the illusion that the eleventh party will not be eliminated. After all, no one knows what Nonomura saw except the screenwriter.
By the end of ps, Ma was holding a piece of paper full of names, all of which were characters in the play. Names are divided into black and red, black is alive and red is dead. Finally, some people saw it was black, others saw it was red. I see eleven is red and Tsuda is black. It is very likely that Tsuda didn't die in the early generation, escaped through the ability similar to Eleven, and has been hiding.
