Editing this as I didn't realize what comment section I was in at first; thought it was a GT question. For this game, consider taking off the ear clips. This will turn off the hypno mechanics in the fights, which will streamline them a lot if you just want to get through a number of them quickly.
I see. To me this game seems really curious but not in terms of gameplay (as it is grindy even without clips to me). I am more interested in the lore of it all. Does it actually have lore? Like explanations for who the creepy guy is, why our guy is familiar with the clips and all that?
It does! Some of the basics are laid out here, but more is explored in GT. There's actually a whole optional lore-dump computer. As for why he's familiar with the clips, examine the notes you pick up at the beginning and consider the meaning of "delta."
