The world's strongest magician who carries "the crest least suitable for battle" searches for companions to fight together. The ones fit to be his companions would be...!?
here are 4 types of crests in this world. each person can unlock one of them. our main character has the weakest one but he studies the crest on his own and finds out that his crest can become the strongest one with further studying of crests. then after becoming overpowered he goes off killing all dragons on the continent and after killing them he goes to seclusion for 200 years to further perfect his crest.
its an exact copy of "strongest mage with the weakest crest" same character names and shit like the dragon has the same name, looks the same and the sorcerer looks the same too like how blatantly do you want to copy something jesus
