In the harsh region known as the borderlands, humans must fight an endless battle against demi-human creatures that come at them relentlessly, intent on taking their land and their gods. A young boy named Kai, fighting to defend his village, sustains a life-threatening injury that causes him to regain memories from a past life. If you're not a guardian bearer, it's like you're playing life on hard mode... Kai's newfound knowledge gives him a new sense of the unfair rule set that governs the world around him. One thing is clear: For those without a god to serve as their guardian, life is a constant struggle for survival. Thus begins the epic tale of a young boy's ascent into a vast world filled with magic, bloodshed, and mystery. (Source: J-Novel Club)

A few young girls with strange powers and a tree that has grown through a railcar cling onto life in a desolate land, searching for its last reservoirs of water. Their routine struggle to survive is interrupted by the arrival of Wakaba, a boy with no memory beyond his own name. The girls and their new companion commit to a perilous journey across seas of burning red fog—all in order to find what they need to sustain themselves on the more distant, dangerous islands swarming with robotic bugs. Their ultimate fate will be decided by their own strength, along with Wakaba's curious ability to understand the Kemurikusa: mysterious glowing leaves with wondrous powers. Besides the girls, Wakaba, and the hordes of ravenous bugs, the Kemurikusa are the last sparks of life surviving in this land. How did things end up this way? Why are there so many empty buildings with no one to live in them? Wakaba and the girls lack the answers to these questions, which means the truth can only be found within the Kemurikusa.

An innocent young man, Ikuroo, has a parasite known as Baoh implanted in his brain by an evil organization, Doress. The parasite makes him nearly immortal and gives him the ability to transform into a really powerful beastie when he's in trouble. Doress intends to use him in some sort of ploy for financial success, world domination, or something along those lines, but when they're transporting him on a train, a young psychic girl, Sumire (who's being held by the organization due to her abilities), sets him free and the two escape together. Of course, Dr. Kasuminome is the mad scientist behind the whole Baoh thing, and he isn't about to let his test subject get away and he has considerable resources (including some superpowered lackeys, as well as a small army) at his disposal.
