One hundred years after the extinction of all dragons on earth, Matthew manages to awaken as an SSS-rank Dragon Tamer—only to become a “useless genius,” considering there are no dragons for him to tame. As a result, his girlfriend abandons him; his sworn brothers look down on him; and even his usually amiable mentors cast cold, disdainful glances his way. But what no one knows is that Matthew also awakened a power known as the Dragon Rearing System. Under his care, a fiery-red dragon egg quietly hatches; and now, the legendary Five-Colored Dragons are making their return one by one!

Their union leaves her carrying nine divine eggs. At the Birthing Ceremony, Serena exposes the villains' conspiracy and joins forces with Nereus to defeat them. Together, they abolish the merfolk tail-caste system, and Serena ascends as the Sea Queen, ruling the deep sea alongside the Sea God.
