The doctor’s name is 堤内, seemingly, read as Tsutsumiuchi. Googling gave a wiki page about a baseball player named Tsutsumiuchi Takeshi. https://ja.wikipedia.org/wiki/堤内健
Aspi mentioned the OP lyrics being about making a choice. I was thinking along those lines but there is also a line about how everything was already decided. I still hope that they force Yuu to make some choice, but I feel the chances aren’t very high.
Old scientist guy is obviously Kumagami from the future, like duh. In all seriousness though, there’s been nothing indicating possible time traveling in this show, only time leaping. Maybe there’s a power user there that can predict the future, downside being is that they can only predict people’s deaths and nothing else, and old scientist guy happened to hear about it. Not that there’s anything concrete whatsoever to support this theory.
I always wondered if there was a time limit on Plunder, like if the abilities return to the original user or just disappear after a while. Permanent plundering seems, I dunno, too un-flawed? Unless having to leave your own body for five seconds is supposed to be a flaw? Well that’s a convenient flaw. There may be a severe backfall to it we just don’t know about yet.
The whole stuff about “even if he forgets someone precious, the monster will continue to challenge fate” is making me really hopeful (afraid?) that things won’t turn out all well and good.
And yeah, ‘The World is not in here’ is the Google translation.
What’s with the four minutes of dead silence at the end there?
It could be a case of its greatest strength being its greatest weakness depending on the situation. We see that in this episode, for instance what if Yuu needed Nao’s power for (unspecified something), then he would steal her power from her leaving her powerless from that point on. Like you said a bit of a convenient flaw, but still a flaw.
