[X] Answer truthfully. You'll tell everyone what you saw.
-[X] You were told by someone whose approval you once looked for that you make everything actively worse just by existing.
Honestly, while Tokei tried to kill us, I don't think we fear him or someone like him, we are strong, and even if we met someone stronger there is still some way we could deal with the situation in most cases.
As for the whole "The world isn't real" thing, honestly while it may have been fiction to us in our previous life and while we have some tidbits of meta-knowledge, it doesn't really seem like Daisuke thinks this, he's made friends with people who were supposed to only be characters in a story sure, but he also discovered that they have a deeper personality than what was shown there, he's also made friends with a lot of people who weren't part of the original story and who certainly seem to be just as real as him, at some point you have to wonder, if a simulation is good enough to seem real, feel real and be indistinguishable from reality.....is it really fair to call it fake?
But the greatest problem with the above option is actually one of the reason I think the option I chose makes the most sense, if Daisuke thought the world wasn't real he wouldn't care as much as he does about it, if something were to happen to Ino or Mother or one of his other friends....would he really be unaffacted by it?
I don't think so, in fact I think it would be really easy to assume that if something DID happen to them it could be considered our fault, by our very existance, the world we're living in is certain to be different from the one we still have some memories of, there is no guaranteed Good Ending here.
Because our presence has already caused the butterfly effect to occur and go out of control, and if something goes wrong and the world goes to shit, by say, exploding in another worldwide conflict, Daisuke could very well think he is responsible at least in some way, it's not necessarily true (Vesvius seems to have changed some things with regards to the world that we definitely didn't cause like more competent Jonin) but Daisuke could certainly be very afraid that it is his fault if the world ends up worse than he remembered it being in his memories.
