GETTING A GUILD MARK IS MANLY!
Sorry, couldn't resist...
He wasn't the strongest when he first joined the guild, he had been a sensitive, poetry-loving kid, rather similar to... Lisanna.
But he'd been like Mira in many ways too. One of those ways had been his devotion. He'd always loved his family, they were the centre of his World. When they joined the guild that family only grew. So he got his mark, white like his families hair across his neck. It was a strange feeling, having the stamp being pressed against such a sensitive area but he didn't mind. It was an important area. It was one of the most targeted spots on the body because it held a vital artery, one that when pierced would instantly kill anyone. So he kept the mark there, as a message to himself. A promise.
As long as blood pumped beneath that mark, as long as he had that beating he'd devote them to his family. For his sisters, for his guild, he'd fight and live for their sake, until his last breath.
After all, that was what a real man did after all.
