In a post-apocalyptic future, where the world has turned into a desert and the remains of humanity live under the rule of the Third – beings with a third eye on their foreheads. Accompanied only by her tank's AI, Bogie, Honoka tries to make a living as a handyman on the edge of civilization, and she tries to avoid resorting to violence as much as possible; but when situations demand it, she and her sword become a force to be reckoned with. When Honoka is hired by the mysterious young man named Ikus, the Third suddenly take great interest in them; and thus, Honoka’s story truly begins…
Both series are more about story and plot than action, however both series do offer the small doeses of high quality action to keep the veiwer interested. The plots are both very in depth and both series will be confusing at first because there is so much going on and so much for the veiwer to notice.
If you liked one then you certainly will like the other, indepth plots with good action character development and both have great endings.
