Magi Craft Meister - Chapter 666

Born without a mana circle into one of the most powerful family of hunters in the country, Luthra was the ultimate failure. Deemed trash and disowned, he was cast out with nothing but the clothes on his back and a cold, self-hating resolve.For five years, he trained his body to its breaking point, only to discover his weakness was a lie. His power wasn't absent—it was a paradox. A 'Negative' mana circle so volatile it had to be sealed by a god at his birth, lest it annihilate his very soul.Now, the seal is cracking. To prevent catastrophe and seize his own destiny, Luthra is given a key: The Negative Leveling System. In this world, power means leveling up. For Luthra, true strength is found by leveling down.Armed with a simple industrial chain and an unshakable pragmatism, he begins his hunt. Every monster core he absorbs pushes him deeper into negative levels, unlocking twisted skills and an incomprehensible strength the world has never seen.They called him a zero. But in a system where Level -10 is stronger than Level 1, Luthra is about to show them what true power looks like from the bottom.

A massive underground labyrinth awaits in an alternate world of swords and magic. With a game-like system much more familiar than spells and magic circles, Beatrice has managed her magic and risen to the position of “strongest”, but she still has her worries.

“Bghohhh!! Bshrrrr…mumble mumble…”

One day, two forum posts titled “I Seem Unsuited for Dating” appeared on Promontory Forum’s Feelings board nearly at the same time.

User A: 「I have a severe case of mysophobia and possessiveness. I cannot accept it if my girlfriend has had relationship experience. I went to see a psychiatrist, but I haven’t improved. I might truly be unsuited for dating.」

User B: 「I think I might be unsuited for dating. I very much enjoy the ambiguous phase of sounding out each other’s feelings, but after becoming official, if they want to hug me, or perhaps kiss me, I will immediately feel nauseous.」

Internet User: 「I beseech that the two of you be together. Don’t go and harm anyone else.」
