On an ordinary day, Lucius stumbled upon a strange, run-down shop. At first, he assumed it was abandoned—until he stepped inside.[You have entered the Universal Alchemy Store.][Congratulations! You are now the store’s owner.][Please craft your first potion.]Lucius blinked. 'What kind of joke is this?' But as if guided by an unseen force, he followed the instructions. Minutes later, his first creation was complete.[Love Potion: The drinker will fall in love with the first person they lay eyes on.]Lucius swallowed hard. 'Wait… does this actually work?'Before he could process it, the shop’s door swung open.Standing in the entrance was no ordinary customer—she was an elf. Long, pointed ears, mesmerizing green eyes, and a body sculpted by the gods. A visitor from another world.A dangerous thought crept into his mind.'Should I test it on her?'

The emaciated old man with an alien-like appearance grinned maliciously, while the young girl cried and howled.“Worm, worm, worm, worm, worm, worm...”Countless worms surged towards the girl like a tide, seemingly intent on devouring her completely.The girl instinctively closed her eyes and let out a desperate wail.“Someone... save me!”A breathtaking beam of light cut through the dimness, dispelling the girl's fear and the swarm of worms that filled her vision. Accompanied by a voice that was young but carried a hint of sunshine.“It's okay, I'm here. Big brother is here to protect you.”The boy with purple hair and purple eyes held a scythe in his hand, blocking in front of the girl, and issued a declaration of death to the old man.“You deserve to die, Zouken Matou. No, Makiri Zolgen!”
