Update now there are 2 ways to deal with this, my method of brute force, the other is "fixing" the file

1st method fix the file yourself by following this other guide linked by 十六夜咲夜 (Sakuya Izayoi)

2nd method, brute force when the error appears you may think your screwed or the game is stuck, but not so, by holding the enter key you can slide show the battle, whilst holding enter mash one of the other menu buttons for your item to use or attack, when selecting an item mash the up or down arrow key to scroll, in order to get past the barrier part you must defeat either Futo or Tojiko,

The best way to do so is to use Yukari and attack buff her with Tenshi or a p-up item, i'd also reccomend giving Yukari an accessory that prevents sleep, next when you buffed up, focus soley on Futo or Tojiko and use Yukaris special attack "Fantasy Manjo-parasol",

it does tons of damage so it should only take 1-2 attacks to take your target down as they both have 1000 hp, after Futo/Tojiko is down the barrier thats supposed to spawn will disappear and the error message will stop, thus the game will go back to normal, now take out the other one and then Miko as fast as you can before Miko can revive the 2, fortunately this is the only fight in the game with this barrier move.
