Given the timer countdown to prevent grinding and the fact that I can't go back to previous palaces to pick up Personas I may have missed, I suspect that the Okumura fight is just a solid wall that I won't get past on this playthrough.
With the resources I have available, it's just not possible for me to defeat the green guys in two turns.
Perhaps one day, I will start from scratch and try to 100% everything so I stand a chance. But I think for now I'm going to move this game to the "Did Not Finish" column.
I do not think that I am the sort of person to finish an Atlus game. I thought playing on easy would be enough but...it just wasn't.
Still, it was a fun 70 hours. So, though the moment is bittersweet at best, I abandon this game with a light heart.
