I guess at this point an anty-fantasy player can go with this reasoning.

Spoiler for higurashi:

batler's memories work in the same way as rika's memories did, everything that piece batler does gets trasnferred to meta battler's memory too, except for the few minutes before piece battler dies; the only difference is that piece battler is not getting any memories from the previous worlds back.
Still, that means that we can only 100% trust anything that peice batler has witnessed except for the little bit of time before he dies (it's not necesary to make the cut at midnight, if piece batler somehow dies at 2am then we can trust the midnight); there is no point to make up /modify events witnessed by batler in that case, because he will get the memories and discover that the stuff was a lie anyway.
