A Dragon's Adventure.

Kazami Ryuto is a 16 year old boy that is trying to achieve the highest rank an Adventurer can obtain which is "Superior Platinum." Upon making an oath to obtain that rank as a child, Kazami trained everyday to become strong enough to achieve his goal, but when the time came for him to become an Adventurer, he failed to summon his weapon which is required to achieve your first rank and begin your adventures. Or so he thought.
