Heraldry! Belt Is Weak? Where's the Knight's Belt!

Those who are born with a coat of arms are born with magical powers! This is a world where everyone will reveal their own crest and awaken their magical powers when they reach the age of seven! Someone awakens the summoner profession, summons monsters from other worlds, and opens passages to other worlds! Someone awakens the power of the elements and burns the world with every move he makes! There are also people who have awakened weapons and can split mountains with one sword and cut off seas with one sword! Qin Mu traveled through time and awakened a emblem when he was five years old, but this emblem... Why a belt? Also, what is the sign-in system? Game consoles are too cool, right? Wait a minute, the belt + system + game reward variant—— Next, please watch out for my transformation! I, Qin Mu, will leave my legend in this world!
