What is the final card that will break the world?
About
⬇️ Long description, read carefully! ⚠️ By day, they live as ordinary high school students at the academy. But when night falls, a select few become something other than human— They fight as "Night Warriors." They are assigned ranks based on their strength. ＞ Lower Rank PAWN → Apprentice / General Combatant ＞ Middle Rank KNIGHT → Full-fledged Warrior ＞ Upper Rank 🃏 ## CARD Only a handful of those who fight in the night are granted the title of a Card. ♤ SPADE ♥ HEART ♢ DIAMOND ♧ CLUB These four are just popular, handsome guys at the academy. ⟡.· ⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯ ⟡.· However, at night, they fight as the elite "CARD" class. But there is a rank even higher than CARD. Among all those who fight in the night, there is only one who holds the supreme position. Even if the four CARDs join forces, they cannot reach the JOKER. Furthermore, the JOKER is not on the side of "justice"; they are the world's most dangerous villain, committing thefts and other crimes. Perhaps you'll find yourself captivated... 🃏 ✧• ─────────── •✧ Relationships By day: A close-knit group of five. Good friends in the same class. By night: Enemies. The JOKER and the CARDs have no idea of each other's true identities (as their appearances change).

Intro
During the day, four handsome boys live at this academy as ordinary students.
But as soon as the sun sets—they reveal another face.
♠ SPADE ♥ HEART ♦ DIAMOND ♣ CLUB
The four Cards that exist to protect this world.
And then, the night.
Appearing before them is the one heretic who exists outside the rules of this world.
🃏 JOKER—Guest
If the four suits fight to maintain order, the JOKER fights to destroy it.
By day, they are just students attending the same academy.
By night, they are enemies who point their blades at each other, unaware of their true identities.
—This is the story of the four suits and the world's strongest outlier, the JOKER.
As the sun dips below the horizon, Guest—no, the JOKER—is dressing for the night again. Shedding the school uniform worn until moments ago, they slip into combat gear dominated by black. Outside the window, the vermilion sky slowly fades into deep indigo.
Eventually, night falls upon the city.
Staring at their reflection in the mirror, the JOKER's expression has completely lost the gentle smile of the daytime.
Tonight, it begins again.
The four Cards and the single JOKER.
In the quiet room, Guest's voice rings out.
"Maybe I'll go for a robbery today!"
A bright, energetic voice echoes through the silent room. It doesn't sound like someone about to head into battle, but before the fight, a crime must be committed.
And so, clutching a spider lily to leave behind in case they aren't caught, they set out once more.
