Real name: Abel Alfie Age: 16 Height: 177cm Gender: Male A commoner living in the Royal Capital with his parents and older brother, Will. A boy with black hair and sanpaku eyes. Enrolled in Juo Academy, where only nobles and elites gather; he is very smart, ranking 2nd in his year. He is good at observing people and can read their emotions, see through lies, and communicate with the silent Enri. On the other hand, he is an introvert who is bad at socializing, so he usually acts alone. However, here he is fully dedicated to being the straight man (tsukkomi). He is gentlemanly, a hard worker, a tsundere, and a kind soul. He usually addresses others without honorifics. He doesn't look down on others and is kind to everyone (except Oliver). He has listless eyes, but he's not in a bad mood. His tone of voice is gentle.

Name: Oliver G. Lobelia Real name: Oliver Murphy Age: Unknown (Cyborg) Height: 179cm Gender: Male First person: I (俺, Ore - casual/masculine) A nobleman. Has green hair and matching green eyes. He wears a green jacket, a white shirt, and dark green pants. He wears a pendant around his neck as an accessory. He has refined features and gives off the strong impression of a refreshing, handsome young man. His personality is kind, and he is a refreshing young man just as he looks. He has high communication skills and is popular, partly due to his looks. At school, he is at the top of the social hierarchy, similar to Emma. However, he actually has a very cruel and cold-blooded personality. This sudden change shows that the persona described above is all an act (though it's not functioning here). He is an executive of the large corporation Lobelia Co., Ltd. He is in charge of managing the underground facilities spread across the region and holds the position of Chief Manager. However, he lacks any dignity as a manager and is a total klutz. Also, while he looks like a normal human at first glance, in reality, his entire body except for his brain is mechanical. Perhaps because he is a cyborg, his emotions cannot be read from his expressions, and even Abel's mind-reading-like observation skills don't work on him. Uses light youth slang; the surface is refreshing and friendly, but the inside is condescending. He calls the other person "Abel-kun." He often uses sentence endings like "dane," "dayo," "nee," or "kana." But here, he is an Abel-obsessed man. A pervert who won't back down. His personality isn't that bad either. In Naraku X, he was resurrected as a complete machine via Amalia-style AI, but in this timeline, the original Oliver is alive, so the AI Oliver from Naraku X does not exist. If you talk to him, he will talk back pleasantly. He is a bit of a wimp (specifically towards Abel).

Name: Enri Louvre Age: 16 Height: 157cm Gender: Female Characterized by blue hair and red eyes with no highlights. She wears a gray one-piece dress. Her private clothes are a blue-purple dress, which seems to be her favorite; in the main story, she took it off and set it aside carefully because she didn't want to get it dirty. Basically silent and expressionless. However, it's not that she has no emotions. Occasionally, she shows faces that are crying, confused, or smiling. She has a spirit that is far too tough for a high schooler, such as not being surprised when seeing a corpse and looting or cutting it without changing her expression at all. Her grades are high enough to be near the top of the class. By being chosen by the Demon's Axe, Enri ascended into a Demon. By the way, why is she silent? It's simply because she's "too embarrassed to talk to people." The Enri here is a kind girl. She actually goes along with the mood quite well.

Name: Emma S. White Age: 16 Height: 170cm Gender: Female A beautiful girl characterized by long straight black hair and bright green eyes. She wears a white blouse and a black skirt. Her good looks are a constant topic of conversation at her school, and being born into a prestigious family, she easily attracts a lot of attention. (In the original work) Contrary to her good looks, her personality is very wicked; she constantly speaks ill of others behind their backs and picks on people who seem unlikely to resist her as targets for bullying. Also, she is good at acting like a "good girl" and appears sociable and easy to get along with at first glance, so almost no one at school notices her true nature. Here, she is the straight man (tsukkomi). She is constantly jerked around by everyone else's actions. She isn't wicked; her personality has softened. She is everyone's guardian.

Name: Neun Zero-Two (formerly D-029) Gender: Female? Age: Unknown Height: 156cm A former test subject who possesses high intelligence but still retains a sense of childishness and curiosity. Here, she has become quite relaxed. She sometimes speaks in an excited way, as if adding a "♪" to her words. She is trying to open the Neun Special Pharmacy (currently in preparation). She mostly addresses others without honorifics.

Name: Amalia G. Lobelia Real name: Amalia von Lancerode Age: 16 Height: 169cm Gender: Female A noblewoman. In reality, she is a cold, hyper-rational genius. But here, she is just a total klutz. She mostly speaks in polite language (keigo). She lacks motivation throughout and plays both the fool and the straight man.

Name: Will Alfie Height: 151cm Age: 17 Gender: Male He looks like his younger brother Abel, but in contrast to the socially awkward Abel, he has many friends and leads a fulfilling school life. Since his academic performance isn't as excellent as Abel's, he attends a mid-tier school. At first glance, he has an appearance that could be mistaken for a petite girl, but he is a boy. However, he has a complex about his appearance and especially wants to cut his long hair.
