Flowing water has no shape, drifting wind leaves no trace, and all reasoning depends on the heart. Today's case is related to an urban legend… Legend has it that if you pray to the Hell Puppet Master at midnight, telling him your information and your deepest resentment, the Hell Puppet Master will reveal a complete criminal plan… The only one to uncover the truth is a criminology professor with the nominal title of consultant but far more power than most—Gao Yuanzhao. (I've made some appropriate modifications to the cases to ensure they're exciting, and I won't hesitate to include any female characters; you can check the related sections of the work for more information.)

Illya: "Yu, you went to another world to gain the power to save me, right?" Emiya Yu: "That's right." Chloe & Miyu: "Then what's with all these girls sitting on the sofa?" Upon hearing this, Emiya Yu looked at the Burst Mage, the Blue Ribbon Goddess, the Gluttonous Sisters, and the Elf Family sitting on the sofa, and said naturally: "Oh~ my dear Illya, Miyu, and Chloe (Kuro), saving the world and chasing girls don't conflict, do they?"

Shimizu Mitsuki looked at Hyuga Hiashi with exasperation: "What are you calling me 'son-in-law' for! How many times have I told you, use your job title when you're working!" Sarutobi Hiruzen immediately said, "Mitsuki, look at my fifty million..." "Fifty million? Three hundred million!" Shimura Danzo immediately got drunk: "Mitsuki! Are you preparing a surprise for us old guys?!" Shimizu Mitsuki just shook his head and remained silent. How high does one's position have to be to be considered high? Back home, Yukino Yukinoshita had a blank face. "What's so good about that Sakayanagi Arisu? Why are you so infatuated? Tell me, I want to learn from her!" Shimizu Mitsuki just sighed and replied, "I'm just loyal to love." "But you're loyal to your love for them!" Shimizu Mitsuki didn't want to argue, he just wanted to say, "Let the evil wind of everyday anime's beauty trap blow in!" (Harem, minor ensemble cast)

"Commander of the Ninth Shadow Legion, Ainz Ooal Gown, requests to fight for my lord!"

The skeleton in the deep purple robe knelt on one knee, its ghostly eyes gleaming with unwavering loyalty.

"Go on, Old Bone, keep your spirits up, don't lose points! Give that old hag, the Fake Witch, a little shock."

Natsuki Subaru sat lazily on the Sky Throne and casually waved his hand.

In an instant, tens of millions of shadow warriors, skeleton knights, dragons, and mages surged out like a tidal wave, covering the sky and instantly turning the earth into a pitch-black ocean.

I, Natsuki Subaru, also known as 486, the script master, the god-slayer, the demon god, the master of the Witch of Deception, the strongest Servant, and the number one unranked powerhouse...

I, Natsuki Subaru, am the most powerful Shadow King in the world of crossover anime!

Looking at the dilapidated Yorozuya before him, Tengu Ginyu fell into deep thought...

"Why are there still weirdos in this world?!" Tengu Ginyu put the Time Driver into the Four-Dimensional Chrysanthemum, plopped down in a chair, and burst into tears.

Witch's Journey + Undead Civil War with Ainz Ooal Gown + Re:Zero + Fate + A Certain Magical Index + One-Punch Man. I love Misaka Mikoto's corpse, a body that witnessed darkness yet remained unyielding, radiating youthful vigor. I love Natsuki Subaru's corpse, the thousand-faced remains torn apart by reincarnation, each piece of flesh recording 486 kinds of despair's fragrance. I love the corpse of the witch Elaina, the traveler's corpse recording information about measuring the world. I love Kamijou Touma's corpse, the savior boy falling into eternal slumber, and I will never let you disturb his death! I love the emotions that living beings show in the face of death, and I hate those undead who walk on the earth with twisted souls. Facing the Undead King of the Great Tomb of Nazarick before him, Ron pointed his spear and glared angrily, saying from the bottom of his heart: "Skull, I will bury the soul within you, and finally, send you into the embrace of death!" The undead civil war between necromancer and the Undead King has begun! My name is Ron, a necromancer who occasionally travels through worlds. Are you trying to say I'm overestimating myself? Sorry, in a necromancer's dictionary, there's only whether I want to do it, not whether I dare to do it!

Sincerity is paramount, Takagi Akito admires him immensely, Kashiwagi Eri and Eromanga idolize him fervently, Shiina Mashiro and the Fallen Saint Kuroneko insist on becoming his apprentices… He's hailed as a once-in-a-millennium genius, a prodigy kissed on the hand by the god of manga, but in reality, he's just a soulful artist like ONE. So why is he able to create such popular and critically acclaimed manga? It's simple: he traded his life for it. Of course, besides manga, you can also trade for girls, but that depends on popularity. So—Headhunter, don't come any closer! [Lazy Lin]

It's common knowledge that pink-haired beauties are generally gentle, kind, considerate, and virtuous—ideal girlfriends and wives. Watanabe Yuuki, transported to another world, is surrounded by such beauties: his childhood friend is pink-haired, his neighbor is pink-haired, his school seatmate is pink-haired, the girl in the next class who likes him is pink-haired, his teacher is pink-haired, the stalker girl who's been following him is pink-haired, the beautiful girl he meets is pink-haired, and even the alien is pink-haired. Pink-haired is fine; they're all cute, and he likes pink-haired girls, so finding a girlfriend and living a happy life shouldn't be difficult. But his childhood friend went to study in England, his neighbor is a socially awkward seamstress who stays home all day, and his seatmate is also socially awkward and plays in a band. For some reason, the stalker girl who's been following him is out of the question. He can't betray his ancestors, can he? The beautiful girl he meets seems to have some mental issues. The alien is another story—what about being raped? All the pink-haired girls around him seem a bit off. Why is finding a girlfriend so difficult? So, Watanabe Yuuki turned his attention to Goto Jiri, the most normal-looking among the group of pink-haired girls. Goto Jiri: Yuuki-onii-chan, I'm only seven years old this year.

Shirou, who had only wanted a peaceful and easy life, was unexpectedly struck by a series of events: system awakening, blank class cards, connection to the Throne of Heroes, Servant summoning, and stepping into the Holy Grail War—thus beginning his irreversible path to becoming a nuclear-powered swordsman! The lingering scent of witches, Unlimited Blade Works, the Feast of Flames, the Fourth Progenitor, the covetousness of evil gods, the frenzied feast of god-slaying… bonds that should never have been forged begin to appear…
