@RiverMaidenYour diary is going to be one that I'm more heavily involved in but it would predict other people's futures but her's.
So say she's walking down the street, one of them could be: "Man in blue shirt bumped into me, found out his girlfriend is cheating on him" or that she's overhearing how one student is bragging about test scores, "<blank>-san was caught cheating on all of their previous tests and is now in the principle's office."
Of course, these are all future predictions. Honka herself will not being seeing her death flag but she will be notified of a DEAD END.
Meaning she could have something like:
I saw Yui running up the stairs.
Miye-chan runs into one of Yui's traps, she sounds hurt.
Yui is somewhere around here, but I don't know where she is.
DEAD END
The idea is that Honoka will know the person who does it maybe, but she will not know the cause of it; basically it will be very vague and probably not tell her outright that "Yui is above me and will throw a grenade at me, DEAD END".
Hopefully this will make sense and will work >.>
I also suspect that we might have to use the Pad some more in the future too so there's that to look forward too I guess
