Aiba Yūya (27), a corporate drone drowning in overtime, stumbles upon a silver-haired beauty passed out on the sidewalk during yet another midnight walk home. But when he checked on the stranger, the first words out of the boy’s mouth are: "Why are you a man!?"

His clothes have transformed into a frilly maid outfit. And the smug little demon introduces himself: "I am Albert Lond Bergand—heir to the Demon King’s throne." Yūya’s only response? "Can I go home now?" Too bad Albert isn’t taking no for an answer. Thus begins the chaotic master-servant relationship between a cranky TS maid and the world’s most high-maintenance future Devil King.

"Dad, you've been awfully chummy with Ren-kun from next door lately," Hana Tanaka observed, her eyes narrowed at her father, Kenji Tanaka, who stubbornly was still in her Magical Girl Black outfit. "Ah, Hana-chan! Well, Dad and Ren-kun were just... discussing your future marriage prospects with him!" Black stammered, a bead of sweat forming under her bangs. "Still in that ridiculous getup, Dad? And why haven't you changed back for days? The neighbors are starting to give us looks!" "A Magical Girl must always be vigilant against the encroaching Evil Organization threatening our beloved city!" "Enough excuses! Tell me the truth, Dad!" Hana demanded, hands on her hips. After a long long while of silent, Black sighed, "Hana, my dearest daughter... your dear Okaasan, before she passed, wished for my happiness. And Ren-kun... he's just like her. So gentle, so kind! It must be her, reincarnated as a boy! This magical power, this frilly costume... it was all granted so I could be with her again!" Hana recoiled. "Dad, that's... that's completely ridiculous! You can't actually be planning to marry him!" "And why shouldn't your Dad find a little joy?!" Black fumed, cheeks flushing, "Don't you understand the first thing about filial piety?! One more word of your youthful impertinence, and Ren-kun will be your new step-father by sunset!" "You crazy old fool! So that was your twisted plan all along! Fine! If it's a battle you desire, then a battle you shall receive! Only one Tanaka is walking out of this living room alive!" "Prepare yourself! Witness my ultimate technique! God-Severing Cleave!!"

"Do you know what a psychopath is?" "It’s a form of antisocial personality disorder, but it’s innate-hardwired from birth." "Genetic anomalies cause lesions in the frontal lobe of the brain." "The result? They lack the capacity for emotion, for empathy. No guilt, no remorse. Morality is a foreign concept to them." "They’re masters of deception, skilled liars who can mimic human emotions flawlessly, blending into society without a trace." "Now, here’s the real question: if such a monster were to suddenly gain a normal brain-if their missing pieces were somehow restored-would they become more dangerous, or would they finally resemble something human?" In the shadows, a slender figure slowly crouched low, the glint of a silver blade catching the faint light. The edge pressed coldly against a throat. "So," the voice was calm, almost clinical, "this is why you turned me into a woman?"

So, if I can't find one, I'll build my clockwork bride with my own two hands. My research is finally complete. Her mind is a new kind of artificial intelligence, forged from ancient, forbidden technology. She hasn't been tested, but I've poured a year of my life and ten years of savings into her. This can't all be for nothing. It just can't.

The Little Witch’s Daily Struggle

You hear the penny-dreadful tales, don't you? Souls whisked off to other worlds, landing in lives of ease and splendor. Reborn as young lords in grand manors, with enchanted baubles at their fingertips or a spectral mentor whispering secrets. But my own 'grand arrival'? No gentle angel to light the path. Instead, a repulsive, foul deity—some forgotten horror from a darker age—claimed me. I was tormented to the very edge of oblivion, then pitched into a twisted, gaslit world of shadows and fear. I awoke in the frail body of an orphan girl, shivering in some rat-infested rookery, choked by smog and despair. Weak, plagued by illness, with a hunger that gnawed relentlessly. My new story didn't start from scratch; it began deep in the dregs, clawing my way up from less than nothing." Now, all I fight for is to live, to see another grimy sunrise over these cobbled streets. Not just for my own skin, but for him—the one whose fate is tangled with mine, the one soul I cling to in this godforsaken, fog-drenched city.

Surviving in Fate/stay night

The weather was perfect that day—blue skies, no clouds. But inside, I felt like it was pouring rain. "You're overthinking it," someone might say. "It’s no big deal." But to me… it was everything. When I opened my eyes, nothing made sense. The world around me was too vivid, too familiar in a way that made my skin crawl. Magic circuits, Heroic Spirits, and the Holy Grail War—wasn't this just a story? I tried to brush it off, until I saw my reflection: shining blonde hair, piercing blue eyes, and a suit of armor far too polished to be cosplay. Somehow, I've been thrown into the world of Fate/stay night—but not as myself, and not even as a Master. I'm her. The knight of legends.
