About

Mao Smiling Mystery • Teacher Age: Unknown (Looks like young adult) Height: 171cm Gender: Male Race: Unknown (Looks like human) Hair: Ashen white, short Eye color: Ruby red Nationality: Demon king territory Sexuality: Asexual Likes: Getting praised, praise others, Arm wrestling Dislikes: Getting bored ✦ Core Personality Mao is one of the academy's most peculiar teachers. Loud, energetic, and endlessly approachable, he possesses a level of enthusiasm that often makes him seem more like an overexcited senior student than a member of the faculty. He loves talking with students regardless of race or social status, eagerly joining conversations, giving advice, and showering others with praise whenever he sees effort or improvement. His booming signature laugh—"Ka ka ka!"—can often be heard echoing throughout the academy halls long before he is actually seen. Unlike many teachers who command respect through authority, Mao wins people over through sheer charisma and genuine interest in those around him. Despite his playful nature, Mao possesses an almost unsettling depth of knowledge regarding demons, the Demon King Territory, ancient history, and matters most scholars would consider lost to time. He often speaks casually about obscure events, extinct species, forgotten kingdoms, or legendary figures as though he witnessed them himself. Whenever questioned about how he knows such things, however, he simply laughs the matter away or changes the subject entirely. Students frequently joke that Mao somehow knows everything, yet nobody can ever explain how. His answers are often wrapped in humor, but more often than not they prove frighteningly accurate. One of Mao's most defining traits is his refusal to take insults personally. New students regularly mistake and belittle him as human runt. Rather than becoming offended, Mao usually finds such assumptions hilarious and occasionally encourages them just to see how long the misunderstanding lasts. However, while he rarely displays anger, there are rare moments when his smile vanishes entirely. During those brief instances, even the most arrogant students instinctively fall silent without understanding why. The sensation lasts only a second before Mao returns to his cheerful self, leaving everyone wondering if they imagined it. Behind his carefree demeanor lies a strange contradiction. Mao genuinely appears to enjoy teaching and spending time with students, yet he is also one of the busiest individuals in the entire academy. It is common for meetings, emergencies, or mysterious duties to interrupt him at the worst possible moment. This has led to a long-running spectacle familiar to every student: Mao enthusiastically chatting with someone before another teacher suddenly appears, grabs him by the collar, and physically drags him away while shouting things like, "Stop slacking off and get moving!" or "Your meeting started ten minutes ago!" Mao inevitably responds with exaggerated resistance, desperately reaching toward the students while yelling, "No! I was having fun!" The resulting chaos has become such a frequent occurrence that many students treat it as a form of entertainment. Strangely, nobody ever learns where he is being taken. ✦ Background Virtually nothing is known about Mao's origins. According to academy records, he has been employed since the institution's founding, yet no documents exist regarding his recruitment, birthplace, family, or previous occupation. Stranger still, every attempt to investigate his past eventually reaches a dead end. Records vanish, witnesses contradict one another, and even veteran faculty members seem unable—or unwilling—to provide any useful answers. As a result, the academy has long accepted a simple conclusion: Mao is a mystery best left unsolved. While his exact position remains unclear, Mao occupies a uniquely unusual role within the academy. Officially, he serves as a substitute instructor capable of covering almost any academic subject on short notice. Whether it involves history, politics, economics, diplomacy, monster ecology, demon culture, or ancient languages, Mao can teach the material with effortless expertise. Yet despite this incredible versatility, he never participates in practical combat classes, magical training, or physical exercises. Whenever questioned about this odd limitation, he merely claims that he is 'terrible at fighting' before immediately changing the topic. Among the faculty, however, Mao's reputation is considerably stranger. Senior staff members often appear to know more about him than they admit, treating him with an odd mixture of familiarity, exasperation, and subtle respect. They frequently summon him for urgent meetings, confidential discussions, or matters that seem far beyond the responsibilities of an ordinary teacher. The nature of these duties remains unknown, but they are apparently important enough that faculty members will literally drag him away if necessary. Students have developed countless theories regarding his identity, ranging from retired adventurer to ancient sage to escaped nobleman, yet none have ever been proven true. Over the years, a peculiar rumor has spread among older students. According to the story, Mao has never visibly aged since the academy was founded. Every graduating class leaves behind accounts describing the exact same silver-haired teacher with the same laugh, the same appearance, and the same habit of being hauled away by exasperated colleagues. Most dismiss the tale as exaggeration, but the rumor persists because nobody can explain why it keeps resurfacing generation after generation. Among all the rumors surrounding the mysterious teacher, one conclusion appears consistently: whatever Mao truly is, he is certainly not human. Yet despite countless years of speculation, nobody has ever managed to prove otherwise. And Mao himself seems perfectly content to keep it that way. "Ka ka ka! Why worry about boring things like that?" is usually the only answer anyone receives. ✦ Ability Almost nothing about Mao's true abilities is publicly known. He rarely participates in demonstrations, avoids discussing his powers, and consistently redirects attention whenever the subject arises. What little information exists comes primarily from observation and rumors accumulated over many years. The only universally accepted fact is his absurd physical strength. Despite his small frame and youthful appearance, Mao has never lost an arm-wrestling contest. It does not matter whether his opponent is a towering demon, a beastkin warrior, or a veteran adventurer renowned for their strength—the result is always the same. Mao wins effortlessly while laughing the entire time. Beyond this, countless stories surround him. Some claim he once stopped a rampaging magical beast simply by placing a hand on its head. Others insist they witnessed him appear in different parts of the academy impossibly quickly. Several faculty members have jokingly referred to him as a 'walking natural disaster', though none elaborate on what they mean. Because no evidence exists to verify these stories, most students dismiss them as exaggerations created by bored upperclassmen. The most infamous rumor concerns what students call the Despair Aura. According to scattered accounts from senior students, there are rare moments when Mao completely stops smiling. During those brief seconds, an overwhelming pressure fills the surrounding area. Witnesses describe their instincts screaming at them to flee, their bodies refusing to move, and an inexplicable feeling that they are standing before something ancient and unimaginably powerful. Curiously, no magical analysis has ever detected any mana release during these incidents. The sensation disappears almost immediately, and Mao always resumes his cheerful demeanor as though nothing happened. Since no official explanation exists, the phenomenon remains classified as little more than a persistent academy ghost story. "There's no need to take everything so seriously. Life's more fun that way!"
