Rento Faina is a Bronze-class adventurer from the Maalt City Adventurers' Guild.

Born as a human, Rentt worked as an adventurer for a decade before dying in an unfortunate encounter with a dragon. Reborn as an undead, Rentt continued his work as an adventurer under the name Rentt Vivie.

As a human, Rentt had a youthful face that didn't change at all during his decade-long career as an Adventurer. He's a charmer, so many girls are in love with him, such as Lorraine, Lily, Fari, and many others. He resembles his mother. After meeting Rina and getting clothes to disguise himself with her help, Rentt now wears a pair of dark gloves to hide his hands, a long-sleeved black robe that hides his arms, and a hood that hides his head, along with a skull-shaped mask that covers his face. Rentt regained his organs and flesh after successfully becoming a unique variant of Lesser Vampire, acquiring smooth, pale skin without scars. He now sports a pair of relatively small black leather wings under his shoulder blades. He also possesses the sharp canines of a vampire that extend in the presence of nearby blood, and crimson red eyes. He is always thirsty for blood.

Personality
Rentt's most notable characteristic and greatest motivation is his lifelong dream of becoming a Mithril-class Adventurer, training every day for 20 years to have the strength necessary to reach that rank. Even in the face of his lack of talent and aptitude, he never gave up.

Because he yearns to reach such heights on his own, Rentt is a solitary adventurer who rarely joins groups. That solitary path, coupled with his perpetual stagnation as a lower Bronze-class adventurer, earned him the nickname "The Thousand-Year Bronze," further distancing him from his peers.

His previous lack of physical strength was compensated for by his insight and street smarts. He could guess Rina's rank and capabilities just by looking at her equipment and movements. Thanks to his habit of forging relationships with every Adventurer he encountered, Rentt developed the ability to assess the character of people he had just met.

Another thing that distinguishes Rentt from most Adventurers is his compassionate nature, which drives him to help those in need. Even after becoming an Undead, Rentt continued to show an honest and charitable attitude towards those in distress, fearing that if he renounced his Humanity, he would be no different from just another monster. He was even willing to risk his life traveling to a dangerous swamp to help the caretaker of an orphanage. Rentt can sometimes be insensitive to the emotions of others, ignoring that some girls have feelings for him.
