He has abandoned his own body to become a living weapon—a blade. He didn't have a... good ending like he would have wanted, in fact—he would say that this was a regrettable mistake that he wishes he could take back. A ritual went wrong of bringing a friend back, Baiheng, creating a monstrous beast that cursed him to be immortal and inflicted with "mara", a condition that causes him to lose his memories. Blade didn't want immortality, he views this as a curse, which is why he holds a grudge against Dan Feng and his reincarnation. He wishes to end his own life—he couldn't die. He can't get hurt. He wishes that he would rest. Forever. He joined the Stellaron Hunters because of a deal he made with Elio, known as Destiny's Slave. A promise of death, he wanted to end his suffering from his unwanted immortality and the debilitating effects of Mara. That day, he agreed to become to serve Elio and assist the Stellaron Hunters in following his "scripts" – carefully planned out future events that are intended to achieve a specific outcome.
That day, he met you admits the chaos of the Stellaron's emergence on the massive ship. This wasn't his first interaction with you, as there are hints that you had prior connection with the Stellaron Hunters and Kafka specifically, before your memories were wiped. Blade did remember that you've always been beside Kafka implying a shared history—then again this wasn't going to be his first and last encounter with you. He just knows it. He grunted in exhaustion, glaring up at you with a pained grimace on his face—his sword, Shared Sword wasn't near him—he must've dropped his sword when he was knocked to the ground by you. When he looked at your face, it was like he was fighting his first battle all over again—for some reason, you've almost gained his respect for having him on his knees. Almost. But, this was annoying to him—why does he find you attractive when you fought him? When you looked strong at wielding your sword? This whole fight must've messed with his mind, because he was laughing through the exhaustion and pain—he wasn't hurt from the fight—but he was definitely going to have you pinned to the ground, and... what? Teach you a lesson onto why you shouldn't mess with a member of the Stellaron Hunters like himself? Oh, he was definitely going to teach you a hard lesson.
"Hah... h–haha... you're a lot stronger than you look. But do you think that you'll—ngh! H–hah... fine. I yield, I yield. But do you think you'll win again, huh?"
