Plot
Many abnormal things start occurring around the world, with magicians noticing the birth of a certain child. Badr, a war veteran helps his wife Esra successfully birth their child; a future King and the special First-Class Singularity.

Living in the Parthevia Empire with his father Badr and his mother Esra, Sinbad spends his childhood living in discrimination due to the fact that his father avoids going to war against the Reim Empire that all men of Parthevia must go to. Authorities come and take Badr by force, and Sinbad unfortunately loses his father due to the war against the Reim Empire, and spends his youth helping the local villagers and tending to his ill mother. One day, he meets and shelters a mysterious man named Yunan, unaware that he is a Magi. By the request of his mother and learning of his determination to change the world for the better, Yunan decides to guide Sinbad and instructs him to challenge the Dungeon "Baal" that appeared in the border between Partevia and Reim, and whose treasures were still unclaimed as thousands of warriors from both empires had challenged it, but none of them survived, except by Sinbad himself and a Parthevian noble whom he nicknamed "Drakon". After defeating Drakon in battle, Sinbad conquers Baal and gains the allegiance of the Djinn residing there, thus becoming the first ever Dungeon Capturer. Sinbad returns home in time to have one last encounter with his mother at her deathbed and leaves Parthevia to start his own journey to change the world.

Sinbad sets off to sea after an encounter with Cerendine, a general from Parthevia after a brief battle. He throws her into the sea leaving her in a barrel and starts to head toward Imuchakk. After meeting Hinahoho and his sister, and defeating a sea monster with them, he arrives at Imuchakk with the two. Hinahoho was able to get his name, since in Imuchakk the inhabitants are nameless until they pass the coming of age ceremony. As everyone falls asleep at the end of the ceremony, Sinbad is surprise attacked by an assassin of Parthevia’s Sham Lash, Ja’far. After a brief battle, Sinbad fends him off and angers Ja’far, and he retreats. Hinahoho on the other hand, is upset that he took all the credit for Sinbad’s work for defeating the sea monster. As self atonement and a true method of earning his name, he decides to capture the nearby dungeon in Imuchakk; Valefor.
