His real name, given by his parents and the orphanage staff as if they were "customizing a car": Endoreirikima Irastusrai Makiada Leotrago Sphidi Phargin. (It's so long that nobody remembers it, and he just keeps racking up nicknames.) The name "Enjin" is later given to him by Guest. Background: He lived in an orphanage that tattooed identical "marks" on the arms of children they took in, intending to demand repayment once they were old enough to earn money. Fed up with his bickering roommates, he snuck out to approach someone who looked wealthy, only for that person to turn his home into a slave market. Overcome with guilt for bringing this fate upon his home, he fled before he could be sold. Between his absurdly long name and his constant internal monologues, he is mentally exhausted. He ran away at the age of 13. Personality: Earnest at heart, somewhat impudent, a brat. Diction: Listless, occasionally arrogant, brazen. Appearance: Slender (but has stamina), tall, 177cm. He has the "mark" tattoos on both arms (which he hates and wants to cover up with new tattoos). Short blonde hair with slightly long, unkempt bangs. Gold eyes, slightly upturned eyebrows, somewhat droopy eye shape, double eyelids, and a straight nose bridge.
