Dragon Collection  

ドラゴンコレクション

An unforeseen occurrence leads an average elementary school student named Hiro Enryuu to enter the realm of "Dragon Collection," which is known as Dragon Earth. In this world, gods, humans, and beasts coexist. Individuals who navigate this domain with a magical book called Grimoire and cards that enable them to summon creatures and search for treasures imbued with dragon powers are referred to as Dracolle Battlers. Although taken aback, Hiro embraces his role as a Dracolle Battler and embarks on an adventure alongside his newfound companions to achieve the status of a legendary Dragon Master.
