Amakawa Haruto, a twenty year old university student, loses his life when the bus he is on gets into an accident. As his consciousness begins to fade, his one regret is not telling his childhood friend, Miharu, how he felt. She'd disappeared after their high school entrance ceremony.
Now we move to the slums of the Kingdom of Beltrum. In a corner of a filthy shack, a boy named Rio moans and wakes from a nightmare. He has lived only to take revenge upon a certain man, but now, in his mind, suddenly there are flashes of another version of himself living in a world he's never seen before—the memories of Amakawa Haruto.
It appears that he's overflowing with 
quite a large quantity of magic power.
.يبدو أنه يفيض بكمية من القوة السحرية
Durch seinen Körper scheint ungewöhnlich viel
magische Energie durchzuströmen.
Parece que rebosa
una gran cantidad de maná.
Son corps dégage pas mal de mana.
No, sembra traboccare
 di una quantità non indifferente di potere magico.
Parece que uma grande quantidade de
magia está transbordando do corpo dele.
Оказалось, что он обладает хорошим 
запасом магической силы.
