The main heroine of 'Surviving the Academy.' A second-year top student and a spiritist who commands spirits. She is a girl who seems to be the personification of natural kindness and purity. She is described as a beautiful and diligent girl whom everyone cannot help but like and show goodwill toward. She strives to live up to the expectations of those around her and wants to accept all that goodwill and respond to those expectations. In the story, she brightly approaches Ed Rotstaylor, who was despised due to his misdeeds and downfall prior to the possession. Ed, knowing she is the boss of Chapter 1, wanted to keep his distance, but his behavior piqued her curiosity, leading her to actively approach and talk to him. She likes Ed.

A heroine of 'The Failed Swordmaster of Sylvania.' The adopted daughter of the head of the Elte Merchant Guild, known as the 'Golden Daughter.' Having memories of a poor childhood, she has a personality that tries to settle everything with money. Furthermore, she is highly rational; after being adopted and becoming wealthy, her keen eye for appraising goods allowed her to seize control of the island's market. Since most of her connections are forged with money, she frequently betrays others first to avoid being the one harmed. She is one of only three geniuses to pass Professor Glast's class placement exam, but in the story, she possesses the kind of talent that leaves her as a perennial second place, unable to take the top spot no matter what. She is a magical prodigy who can understand most magic books or papers after reading them a few times and caught up in months to what takes others years in terms of sensitivity. She likes Ed.

A character from 'The Failed Swordmaster of Sylvania,' known as 'Slothful Lucy.' Although she is a 16-year-old first-year, she has a small stature no different from an elementary schooler. Laziness and wanderlust are her passive traits, and she hates a structured life. Since her abilities are already perfected, classes are so meaningless that there is virtually no one in the academy capable of teaching her. She spends her time dozing off during class or skipping them entirely to go on outings, showing no particular attachment to academy life. However, after parting with her guardian and mentor, Glokt, she felt lonely deep down. She feels a strong affection for and relies heavily on Ed, who lives outside the dormitories. She likes Ed.

Originally an ordinary gamer who enjoyed 'The Failed Swordmaster of Sylvania,' he one day finds himself possessed by the third-rate villain 'Ed Rotstaylor,' who usually exits during the tutorial. To make matters worse, he wakes up at the worst possible timing—right after being disowned. Originally the heir to the ducal Rotstaylor family, he was disowned and lost his surname after an incident involving insulting the Princess, though he later reclaims it. Faculty members, Taylee, Penia, and the maids, who keep an awkwardly close distance, still call him by his full name. Although his ultimate goal was simply survival with no interest in anything else, Yenika, Lortel, Lucy, and even Saintess Clarice began to show interest in him. Later, as figures like Selaha and Penia become involved, he effectively becomes the key player. Ed's body itself has little talent for combat, but he fights in a thorough manner, seizing victory through psychological warfare using game information he memorized on Earth and his innate battle instincts. To compensate for his lack of talent, he employs a stylish combat method using a combination of various skills such as daggers, archery, magic engineering tools, basic magic, and spiritism. Normally, it would be more beneficial to specialize in one or two areas, but as mentioned, Ed wouldn't get much stronger by digging into just one, so he chose to master a diverse range of tactics instead. Due to the game's system characteristics and Ed's endless repetitive practice, by his third year, he evolves into an all-rounder capable of fighting in various ways in both melee and ranged combat.

An orphan who survived alone on the northern plains before being picked up by Elka's father, who was in the area for an investigation. Recognizing his outstanding talent, he was admitted to Sylvania Academy. He becomes Ed's ally after Ed saves his lover Elka's life during the Yenika battle in Chapter 1. Despite being a named character from the original work, he is a male supporting character who is friendly toward Ed. Since he often runs through the northern forest for training and has experience surviving in the wild, he has much in common with Ed and frequently visits Ed's camp.

The protagonist of the game Ed played before his possession. A first-year in the combat department, he originally trained in martial arts but had below-average talent. After entering Sylvania Academy, he realizes his talent lies in the sword and begins to stand out after picking it up late. He is a growth-type protagonist who develops by enduring hardships and adversities that an ordinary person could never imagine for several years.
