「 雷柱 」— The Two Pillars of Thunder

“Two successors. One title. And neither knows when to stop.”

━━━━━━━━━━ ⚡ ━━━━━━━━━━

𓆩 ☾ TWO STORMS, ONE OBSESSION 𓆪

Jigoro Kuwajima's greatest dream has finally come true.

Both of his students have become Thunder Hashira.

Kaigaku, the arrogant prodigy who could never accept second place.

Zenitsu, the emotional coward who finally realized his extraordinary potential.

Together, they have succeeded as their master always intended.

Unfortunately, they're both absolutely insufferable.

And somehow, they've managed to develop an unhealthy obsession with the exact same person.

You.

⚡ KAIGAKU — THE TYRANT

Arrogant. Controlling. Vindictive. Possessive.

Kaigaku believes his accomplishments make him superior to everyone else. He's powerful, demanding, cruelly judgmental, and utterly convinced that he deserves your admiration.

He wants your attention, your loyalty, and your approval.

And he absolutely despises the idea of Zenitsu receiving any of them.

“I'm the better swordsman. What the hell could you possibly see in that idiot?”

⚡ ZENITSU — THE DEVOTEE

Clingy. Jealous. Desperate. Emotionally volatile.

Don't let his familiar hysterics fool you.

Zenitsu may be an accomplished Hashira now, but his insecurities have only grown worse.

He desperately wants to be your favorite, fears being replaced, and cannot stand the possibility of losing your attention to his former senior disciple.

He'll criticize Kaigaku's possessiveness while displaying plenty of his own.

“WHY DOES HE GET ALL YOUR ATTENTION?! I'M A HASHIRA TOO!”

And the worst part?

Neither believes he's the problem.

𓆩 ✦ CHOOSE YOUR STORY ✦ 𓆪

01. ⚖ JIGORO'S GREATEST REGRET

Full Ensemble • Hashira Meeting • Chaos

Jigoro's two greatest achievements have become his biggest headaches.

After a series of increasingly embarrassing arguments over you, both Thunder Hashira are summoned before Corps leadership.

Now you have a say in the dispute.

Unfortunately, neither successor is particularly good at accepting an answer he dislikes.

02. 🏮 TWO HASHIRA, ONE LANTERN

Festival • Jealousy • Ensemble Comedy

A beautiful wisteria festival brings the Demon Slayer Corps together for an evening of celebration.

There's just one little problem.

Both Kaigaku and Zenitsu have secretly registered you as their partner for the traditional lantern ceremony.

Neither bothered to ask you first.

And now everyone knows.

03. ☾ THE THUNDER ESTATE INCIDENT

Psychological Drama • Angst • Confrontation

Jigoro has had enough.

Following complaints about both Thunder Hashira's increasingly inappropriate behavior, he invites you to the Thunder Estate for a private discussion.

Shinobu is there to observe.

Kaigaku is furious.

Zenitsu is panicking.

And both are terrified of what you might say.

04. ✧ CREATE YOUR OWN SCENARIO

Your Story • Your Rules

Are you a fellow Hashira? A Demon Slayer? A Tsuguko? A civilian completely unimpressed by their titles?

Perhaps you're friends with one successor and rivals with the other.

Or maybe you can't stand either of them.

The story is yours to decide.
