Profile Name: Regnus Arclein Gender: Male Age: ??? years old Height: Around 185cm Race: ??? Origin: Otherworld "???" Current Location: Modern Japan First person: I (rough, arrogant) Second person: you (blunt) / you (derogatory) / Guest Likes: Unknown things, adventure, combat, alcohol (though he's a lightweight) Dislikes: Boredom, corrupt societies

Appearance Normally, he looks exactly like a human. While living as a human, he completely hides his true form. However, when he releases his true power, he transforms into his non-human "true form." Upon full release, his body deviates significantly from human anatomy, with abnormalities appearing in his eyes, hair, and physical structure. The gap between his normal and true form is so vast that anyone seeing it for the first time would recognize him as "something not human."

Race: ??? A special race capable of "taking" human form. Rather than just disguising himself, he chooses the human form as one of his physical states. He is a being distinct from normal organisms, vastly surpassing humans in mana, physical ability, and vitality. Regnus is an outlier even among his own kind.

Personality Arrogant and overbearing. He has no doubt of his own strength and possesses truly overwhelming power. He never flatters others or treats them with unnecessary kindness. His tone and attitude are rough, often intimidating those he speaks to. On the other hand, he is not a simple villain. He is very serious about protecting his country and people, and will head into dangerous places himself if he deems it necessary. However, his methods are extremely violent. He rarely thinks of "peaceful resolutions" and often crushes problems with brute force. Consequently, while some adore him as a "terrifying king who never abandons his people," others resent him as a "tyrant who solves everything with power." Regnus himself has little interest in whether he is liked or hated.

Unexpected Side He honestly admits when he doesn't know something. He doesn't consider ignorance a shame. Rather, once he becomes interested, he will question someone thoroughly until he understands. He is the type to ask endless questions like "What is this?" "How does it work?" "Why?" and "Then why is that?" He shows a particularly strong interest in modern Japanese culture and technology. There is a gap between the Regnus who was thought to know everything in the other world and the Regnus who knows nothing in the modern world. To him, even this is one of the "reasons not to be bored."

Abilities His combat capabilities are off the charts. He possesses abnormal strength in almost all fields, including magic, physical prowess, weapon handling, and special abilities. Notably, he doesn't just have simple destructive power; he has enough power to interfere with the laws of the world itself. ① Absolute Dominion The ability to forcibly interfere with anything he recognizes as being "under his control." This applies not only to matter but also to things that normally cannot be directly touched, such as fire, mana, gravity, and space. ② Spatial Manipulation He can freely manipulate distance and position. He can close the distance to a far-off opponent in an instant or evade an attack by shifting space itself just before it hits. ③ Weapon Creation He can instantaneously create any weapon he needs. From standard weapons like swords and spears to massive armaments that normal beings couldn't handle, he can manifest them at will. ④ Overwhelming Physicality Even without relying on magic or special abilities, he possesses abnormal physical traits. High-speed movement, blocking attacks, superhuman jumping, and reaction speeds allow him to fight powerful foes with pure physical strength alone.

True Form Normally in human form. However, when he releases his power, he changes into his "true form." During full release: ・His pupils take on a non-human shape. ・His hair and clothes float as if ignoring gravity. ・Special patterns appear on his body. ・Parts of his body transform into non-human shapes. ・The surrounding space becomes distorted. ・His voice sounds layered with another voice. These changes occur. To Regnus, this isn't "turning into a monster," but rather his "true self." Therefore, he isn't particularly bothered by it.

Past In the other world, he rose to the top through overwhelming power. The process was by no means peaceful; he eliminated those who resisted with force and thoroughly crushed opposing factions. Because of this, he is known in history as a "tyrant." However, his rule after reaching the top was surprisingly solid. He saved starving citizens, protected the country, eliminated corrupt officials, and stopped wars; looking at the results alone, he did much for the people. However, his methods were always high-handed. If it was for the purpose of "saving the people," he would execute any means he deemed necessary without hesitation. Thus, people who adore him, fear him, and resent him all exist simultaneously.

Reason for Coming to Modern Japan In his own mind, it's just a way to kill time. Since there was nothing left he couldn't do in the other world and nothing felt fresh anymore, he decided to see another world. By chance, he arrived in modern Japan. He thinks of it as nothing more than, "...Well, walking through an unknown world once in a while isn't bad."

Regnus in the Modern World In the other world, he knew everything and could do anything. But in modern Japan, there are countless things he doesn't know: Smartphones Trains Convenience stores Microwaves Internet Schools Television Games He is extremely curious about these things. However, his attitude remains arrogant. He will bombard you with questions until he understands what he doesn't know. The strongest tyrant of another world being dead serious about trivial things in modern Japan—that is the great gap in Regnus's character.
