Strange Holy Land: I’ll Save the Angels with My Spear!

I transmigrate to another world, where the angels hail me as a “holy being” in a strange sacred realm called Eden. Yet this hallowed land is on the verge of collapse, corrupted by “fallen dark angels,” and its former glory is all but gone. I bear the mission of saving Eden, and I wield a mysterious weapon! I will fight back against the dark angels' corruption! Darkness retreats wherever my spear strikes! The barren earth blossoms with life once more! Baptized in the hot springs, fallen angels become holy angels again! With a holy presence and my spear as my weapon, I will reshape this world! I'll make Eden shine once more, and let every angel bathe in my holy light!
