"....this Y (:why) is there to be answered."
He might have been a genius type. But now he was a bit reckless and not depended on logic that much. He would always act as if he's brave and position himself at risky situations, but actually he was a slight coward person. Nevertheless, his ego was big. A type of ambitious person and individualist who always put everything at his own interest and advantage. He’s quite skeptic and rude and not bother to care about others.
Deep down, he was a mixture of narcisstic and paranoid person.
Who he was and how he could get here was a total mystery that he’s really curious to find out.
guns and (if needed) the silver knife.
(but he always avoided to use them and hope wouldn't have to use them ever. in fact, the idea he's using them, even for defend was just ridiculous and too incoherent. ironically, he's skillfull on those)
He remembered nothing, not even his name, probably from contusions and concussions he had due to the crash.
The odd is he got (actually was holding) high-tech guns in his hand the first time he opened his eyes from unconsciousness. And checking his pocket of his pants, he found small knife which its holder made of silver .As he looked carefully, he found small fonts embossed on its surface, “a z u r e “.
A small odd ‘Y’ shape and a much bigger-complex something that looked like heart (the true heart that beats makes you alive, not that cute heart related to silly things like love) was revealed in his left arm as he folded his shirt. Both were tainted in black and looked like tattoo.
A piece wrinkled paper (which oddly not lost during whatever chaos before) in his shirt pocket also had that small Y symbol on it.
As silly as it could be, then he assumed and decided to call himself Azure Heart.
