Synopsis

After Lumine and her friends were killed by a cursed gun, they were given a second chance at life in another world as its defenders. Lumine, now equipped with power over time, must deal with... her friends making dumb decisions that would constantly get them in near-death situations; either having dinosaurs chasing after them or having kings waging wars against them.
In this new world, they are faced with clouds that rain lava, and fire. Snakes that are used as light bulbs, a floating ocean, a nation inside of a toad, and more.
Of course, Lumine spends most of her time gaining new powers from skill cards or going on murder sprees to level up.
