Background / History

Pei Renli lived an unremarkable but happy life on Earth. He was an optimistic young man who enjoyed games, had an ordinary academic and family background, and was raised by both his biological parents and godparents. His name originated as a homophone inspired by a bus announcement, with the characters later changed to give it a more respectable meaning 1.

While using the toilet and playing on his phone, Pei Renli suddenly transmigrated to another world—along with the toilet. He awoke in a luxurious room under the care of Lavna, who informed him that he had arrived according to prophecy as the new Demon King and inherited the previous Demon King's castle and servants 2 3.

His first experience as a Demon King was being forcibly sent to the Demon King Arena's Horror Castle trial. He survived by noticing that the ghostly shear-wielding creatures ignored those who remained still, killing a zombie with a concealed spearhead, and escaping when the trial's participant threshold was met 7 8 9.

After returning, Pei Renli learned that the Demon King System would continue to send him into arena challenges. Rather than rely on luck, he enrolled at Naspar's Adventurer Training School to gain information, learn combat skills, and develop magic before the next countdown expired 9 10 12.

Personality

Pei Renli is highly adaptable. Though initially stunned by transmigration and his sudden status as a Demon King, he quickly accepts practical realities and focuses on immediate problems such as safety, food, information, and training 2 3 9.

He is cautious about revealing his identity and distrustful of paths to power that would make him a feared tyrant. Although the Demon King System allows reputation to be gained through notorious acts, he rejects committing evil for easy progress and insists that being a Demon King is a title rather than an obligation to become villainous 16 25.

His sense of humor is often impulsive and socially disastrous. He introduced himself to the entire school with an exaggerated pose and the declaration, “Feast your eyes upon my holy visage!”, gaining five Reputation at the cost of widespread embarrassment 14 15.

Abilities & Skills

Demon King System

Pei Renli possesses the Demon King System, which displays his level, a countdown to the next Demon King Arena event, and Reputation. Reputation is earned when his name or deeds become widely known and can be exchanged for abilities and items 9 15.

• The System initialized fully after he survived Horror Castle 9.
• Its hourglass countdown is Pei Renli's primary motivation for rapid self-improvement 9 18.
• He remains wary of the System because its easiest reputation-gaining methods encourage violence and fear 16.

Universal Language Comprehension

Pei Renli can instinctively understand and use the multiverse's languages and writing systems, including difficult languages such as Draconic and Ancient Elven 10 17 33 47.

• This aptitude lets him bypass much of the lengthy literacy training normally required of mages 47.
• He uses the ability to study spell materials, recognize magical scripts, and modify alchemical runes 17 47.
• The origin of this ability is unknown and appears unrelated to the Demon King System 17.

Rune Magic

Pei Renli pursues spellcasting through rune magic, using written symbols and casting gestures rather than relying solely on conventional spell-model construction 17 18 43.

• Light — His first successfully cast spell during magic class 16.
• Flash — A cantrip used to create a blinding burst; he employed it against Anton and Sheriff Chatin 17 38 42.
• Mage Armor — His principal defensive spell; it can remain active for at least an hour and protected him from Chatin's warhammer 20 42.
• Magic Missile and Burning Hands — Offensive spells used against goblins, though he recognizes that low-level Magic Missile has limited stopping power against stronger opponents 20 40.
• Cat's Grace and Bull's Strength — Enhancement spells used to improve his allies' agility and strength against the oathbreaker monk Anton 37.
• Pyrotechnics — Used alongside Flash to obscure Anton and create an opening for escape 38.
• Force Fist — A powerful close-range spell he has learned, though he considers it unsuitable for rune casting and intends to study through spell-model construction later 43.

Alchemy

Pei Renli studies potion-making to supplement his limited combat ability and financial resources 31 46 47.

• Produces flasks of strong acid, intended to be thrown like grenades 47.
• Produces healing potions 47.
• Improved an alchemical rune until it achieved an active-ingredient utilization rate of roughly 75% 47.

Survival and Tactical Judgment

Pei Renli compensates for poor physical ability through observation, preparation, and situational magic.

• Remained motionless to evade Horror Castle's ghostly creatures after recognizing that they targeted fleeing victims 7.
• Killed a zombie by using the hidden spearhead in his rod 8.
• Identified the abnormal number of goblins encountered during his first mission and warned his party that more were likely nearby 20.
• Recognized evidence of Sheriff Chatin's involvement in the Curtain Star City conspiracy, though he later judged that exposing the sheriff immediately had been reckless 43.

Equipment / Weapons / Items

• Spear of Blessing — Given by Lavna before he entered the Adventurer Training School; activating it releases a conspicuous cross-shaped Solar Flame Burst to summon Lavna's aid 11 14.
• Short staff / rod with concealed spearhead — Used during Horror Castle; its hidden blade allowed him to kill a zombie 6 8.
• Makeshift wooden staff — Used for magic due to his lack of money 48.
• Flasks of strong acid — Alchemical thrown weapons 47.
• Healing potions — Crafted through his potion studies 47.

Relationships

• Lavna — His loyal servant and shadow familiar, created by the previous Demon King to serve the successor. She provides information, medical care, security measures, weapons, teleportation support, and covert protection 3 14 15 20 46.
• Philfi — A newcomer Demon King who saved Pei Renli from a zombie in Horror Castle; they briefly cooperated before being separated 8.
• Kaya Vigreen — Classmate and frequent sparring partner. Pei Renli investigates the rumors of her curse, respects her superior martial skill, and later advises her on friendship and self-accommodation 12 28 44.
• Koura — Rabbit-eared beastfolk classmate, gossip collector, and mission companion. Their relationship is friendly but often strained by Koura's rumor-spreading and teasing 13 28 29.
• Eve — Quiet mage classmate and neighbor who advises Pei Renli on spellcasting. They support one another in missions and magical study 17 28 37 43.
• Gary — Heavily armored classmate who initially fears Kaya's supposed curse. He later joins Pei Renli on the underground research mission 13 48.
• Litia — Tabaxi classmate and leader of Pei Renli's first assigned adventuring party 19 20.
• Alton — Halfling classmate who later recruits Pei Renli for an exploration of the underground research facilities beneath the school 13 48.

Story Role / Major Arcs

Transmigration and Demon King Succession

Pei Renli inherits the role of Demon King, Lavna's service, Demon King Castle, and the System's arena obligations despite having no prior combat power or understanding of the world 2 3 9.

Horror Castle

He enters the Beginner-difficulty Horror Castle event with tens of thousands of newcomer Demon Kings. Survival depends more on caution and luck than direct strength, establishing his need to prepare for future arena trials 4 7 8 9.

Adventurer Training School

Pei Renli enrolls in Naspar to learn practical survival skills. His physical ratings are only E in strength, constitution, and agility, but his magic power is rated C, leading him to focus on rune magic and intensive daily training 11 15 17 18.

Curtain Star City Investigation

Pei Renli joins Koura, Eve, and Kaya in investigating disappearances connected to human trafficking. He disguises himself as a woman to lure Jixiu into a trap, helps confront Anton in the sewers, and becomes involved in the exposure of Sheriff Chatin's conspiracy 28 29 36 38 42 43.

Alchemical Study and Underground Exploration

Following the Curtain Star City mission, Pei Renli spends ten days developing alchemical supplies and improving runes. He is subsequently recruited by Alton to explore the dangerous ancient research facilities beneath the Adventurer Training School 47 48.

Trivia

• The characters in Pei Renli's name were chosen to approximate a bus-stop announcement that inspired his father; the respectable meaning of “benevolence and courtesy” was added afterward 1.
• He gained five Reputation by making an embarrassing public self-introduction at the school assembly 14 15.
• He acted as bait in a human-trafficking investigation by crossdressing, treating the disguise as a practical necessity rather than something shameful 29.
