Thank you for reporting this issue. This is a strange one, I haven't heard about it before.
For some reason the game doesn't seem to find the relevant files for the characters. The picture of the VN scene you posted with all of the zeros means it can't find the event.ini file of the character it belongs to and the picture of the battle screen shows that it can not find the character's sprites, weirdly enough it did find the ones from the player and generics though, as well as the faction logos.
I can replicate the issue by simply removing the files.
Are you using a fresh, clean version of the game or were any files altered?
Did the intro VN scene (the one before the AP screen shows up) work?
Is perhaps an AV Program interfering? During my testing of the initial pre-release version there was one case where someone had to make an exception rule for the game's directory.
Right now my best guess would be that for some reason any file in the character folder can't be read, while weirdly enough all other files load in perfectly fine. If you wouldn't mind, could you please check if, for example, in "Data\Characters\Main\Yumi\Events\", any files are present?
A lot, perhaps too many to ever include all of them! (。^﹏^)
That seems like a great idea for a special comedy event or something along those lines! Could have a big busty clown Waifu.
Thank you, I hope you had a good one, too!
