A spirit was floating in another world's dungeon, missing its memories. Eventually "he" learned to possess other creatures and using the bodies of the beasts in the dungeon, made his way to the outside world. Dragging a young female knight, a pretty young lady, and even a beautiful mercenary into the mix, our protagonist begins his great adventure in this world.

In the world of magic, there lived a kind-hearted prince, Linkenel. Prince Linkenel was born with the most powerful magical power in history. His magical power was so powerful that the king had to seal that power within his body from the time he was an infant, not releasing it until the day he comes of age. On July 1024, on Linkenel’s coming-of-age ceremony, Rieswinn, the God of Water, appeared at the ceremony and attempted to abduct the prince in order to claim Linkenel’s power as his own. As Rieswinn casts his water magic in the hall, drowning everyone within it, to spare the king’s and queen’s lives, Linkenel agreed to join with Rieswinn. As they were about to depart, one of Linkenel’s best companion, a puppy named Lyle, tried to intervene. As Linkenel begged Rieswinn to keep the pup by his side, Rieswinn brutally slaughtered the puppy claiming Linkenel is now his and should not be swayed by anything else.

Shifting to the modern world, Kanba Yoichi, the protagonist, is a high schooler who has been having dreams about Prince Linkenel, who he refers to as his master, since the passing of his mother. However, his dream has always been the same and ends exactly at the same location (where Lyle was slaughtered and Linkenel was taken away) every time for the past six years. Longing to save his “master,” he stumbles across a fortune teller, who gives him a magical coin to “let him see the sequel of the dream he has been having.” After trying to place the coin under his pillow, Yoichi finds himself in the magical world and, there, he meets with his master. And thus, the magical story of the two begins.

The sea in our world has been polluted. All sort of trash were thrown into the sea, making it unpleasant deep under the sea. One of the inhabitant of the sea, Ika Musume (Squid Girl) seeks to exact revenge on humanity for throwing trash into the sea. Clueless about the surface, she seeks to invade humanity alone, trying to rule over the world, only to find herself slaving away at one of the nearest beach-houses for breaking a side of its wall.

Long ago, there existed two different groups of people. One had red blood and the other had blue blood. They co-existed peacefully, but eventually they started to hate each other and a war broke out.
The massive red blood army initially overwhelmed the blue blood, but with the help of new technology developed by Kodo, the prince of the blue blood, the blue bloods were victorious. That technology, called the Haguruma, is a powerful, robot-type machinery capable of devastating destruction.
As the red blood people were enslaved, Kodo realized what monstrosity his people were using his Haguruma for. Helpless red blood people were being hunted down and murdered. Overwhelmed by guilt, Kodo rescued the refugee red bloods and refused to build any more machines. His father, the king, ordered him to be executed, but he barely escaped and now without a home, he must survive on his own.

The story follows a unambitious introverted middle school student called Saike Kuzushiro. After witnessing the death of his childhood friend, Mikan Karatachi, in a road accident. He cries out to God and after a fall, Saike wakes up in bed the previous morning, the day of the accident.

Will history repeat? Can he save Mikan? What power does he have to change the future?
