I, Constantine, Rule Hogwarts!

John Constantine transmigrates to the world of Harry Potter, only to discover that there's far more here than just wizards!

Demons whisper in Knockturn Alley, vengeful spirits howl in the Restricted Section, and even Hogwarts Castle has become a beacon attracting cosmic evil gods!

Luckily, the Codex of Sacred Judgment awakens!

While young wizards are still learning the Levitation Charm, John is already tearing apart S-rank demons with his bare hands, taking resentful alchemists as servants, and building a heroic-spirit maid squad!

Potions Class? Professor Snape, I've got some ingredients from Hell here. Want to learn?

Transfiguration? Professor McGonagall, sorry, but I use my Transfiguration to reshape the laws of reality!

Dumbledore? Old man, times have changed! Your white magic is no match for Chaos Titans and cosmic sweepers!

From exorcist to Lord of Chaos, I, John Constantine, will take control of Hogwarts, hunt gods and demons, and rebuild the world!

When Hermione blooms for me across the chaotic cosmos, I will crown her in the new age I have forged with my own hands!
