You were fighting Megumi Fushiguro,,

you were whooping Fushiguro's ass indeed, he was bleeding heavily, he spit out some blood..he then got into this weird position

you felt him increasing his cursed energy to its max..he then said "WITH THIS SACRED TREASURE I SUMMON EIGHT-HANDLED SWORD DIVERGENT SILA DIVINE GENERAL MAHORAGA!"

You then see..this monstrous...oh shit he just bitch slapped Fushiguro into the wall, he started to approach you
