A Deal With Lucifer (Part I)

Hikari is a seemingly normal high school student.
His innocent and naive character led him to accept a deal offered by a demon called Lucifer,
who promised to fulfil all his wishes in exchange for his soul. Initially unknown to him,
he is actually inherently anything but ordinary;
he is a being who is capable of disrupting the mysterious balance of the three realms
and his life will be relentlessly pursued.
