Chapter 54: Passive-aggressive Letter

Chapter 54 – Passive-aggressive Letter

The city blurred outside. Towering glass, morning light, people bustling down the streets—none of it mattered inside the vehicle. Inside, it was cold, quiet luxury. Almost too quiet.

Rava stole a glance at Lux.

He was leaning against the window, one leg crossed over the other, gaze distant. Eyes half-lidded. Perfectly still.

Too still.

Not sleeping.

Just... thinking.

Probably.

Maybe.

Or maybe he was just zoning out like some rich guy who’d already decided which color Bentley he was getting.

She bit her lip.

Rava hated that she didn’t know.

She wanted to say something—maybe tease him again. Maybe slide a little closer, nudge his knee, test the waters. Maybe do what she usually did when she liked someone too much and hated how much they got under her skin: distract, seduce, walk away before things got messy.

But this?

This wasn’t the right time.

He looked like a statue right now. Quiet, unreadable.

Dangerous.

And... hurting. Even if he didn’t show it.

So she sat still, hands folded neatly in her lap, pretending her heart wasn’t having a one-on-one fight with her common sense.

Outside the car, morning sped by.

Inside the car, Lux was thinking.

Hard.

—

’System.’

[Yes, sir?]

’We need to talk about what the hell happened.’

[Which part, sir? The divine limbo drag, the triple Seraph assassination, or the part where you emotionally spiral when your girlfriend leaves for three days?]

’Don’t push it.’

[Understood.]

Lux’s eyes narrowed as the thoughts flooded back.

Those three angels? That wasn’t normal.

Normal angels didn’t breach Limbo space. They didn’t drag people into pocket realms unless it was a sanctioned cleansing or celestial-level exorcism. But this? This wasn’t judgment.

It was silencing.

And those Seraphim? They weren’t just "rebels." No.

They were high-tier.

Too coordinated.

Too dangerous.

And too off-grid.

’If they were able to cross dimensions like that, they had to be criminals. Escaped ones. Which means—’

[Which means the Upper Realm’s containment protocol failed.]

’And not a single flaming pigeon came down to say "oops"?’

[Correct.]

’Not even a memo. No banner in the sky. Not even a passive-aggressive dove in a tuxedo with a scroll.’

[None, sir.]

Lux’s jaw clenched.

He didn’t mind being a rogue variable. That was practically a résumé title.

But being attacked—ambushed—in their jurisdiction... and then getting total radio silence?

Nope.

Unacceptable.

’Prepare an official message to the Celestial office.’

[Ah. The passive-aggressive formal letter option. Shall I open the "Professional But Petty" tone setting?]

’Of course. Don’t forget the bullet points.’

[Understood. Drafting message. Will include bullet points and veiled threats masked as legal courtesy.]

’And make sure the subject line is just: "Regarding That Time I Almost Died."’

[Delightful.]

Lux stared out the window.

Calm on the outside.

Inside?

Already flipping through bullet point phrasing.

Subject: Regarding That Time I Almost Died

Dear Esteemed Custodians of Light,

I hope this message finds you radiating divine harmony, sipping cloud nectar, and enjoying the privileges of a bureaucracy that somehow allows high-tier Seraphim to breach cross-realm space and try to murder people on vacation.

I don’t normally reach out—mainly because I thought we were all doing our jobs and playing nice under the terms of the Interplanar Accord (remember that thing you printed in gold and swore on?). But after recent events, I felt compelled to take a moment out of my very busy recovery to highlight a few items for your consideration:

o Seraphim-class entities engaged in unsanctioned cross-realm aggression.

They dropped into the Mortal Realm like unpaid interns with wings and tried to erase me from existence. Not even a "This area is being cleansed by holy forces" warning label.

o Limbo drag detected. Unauthorized. Undocumented.

They didn’t just fight me—they yoinked me into Limbo. Which I’m pretty sure is not covered under your basic angelic engagement policy.

o No correspondence from Upper Realm officials.

Not a scroll. Not a bird. Not even one of those creepy whisper-visions in my dreams. Frankly, I feel ghosted. We had something special, didn’t we?

o No restoration or healing protocol provided post-battle.

I had to fix myself using emergency demonic regeneration and a dark healing spell I unlocked by consuming their weapon. Yes. That’s how bad it got. I literally ate the heavens to survive.

o Strongly considering formal complaint via Interplanar Accord.

Not out of malice. Just... legally righteous indignation. You understand.

At the moment, I am alive (shocking, I know), mildly pissed off, and actively resisting the urge to retaliate with a lawsuit, a public statement, or worse—an open letter to the Divine PR Department.

Please advise on the following:

o Whether said Seraphim were officially sanctioned to operate in Realm C-342.

o If not, what containment protocols failed and when you plan to fix them.

o Who exactly is responsible for my dry cleaning bill and internal bleeding.

I look forward to your response.

Or not.

I’ve started keeping receipts either way.

With reluctant admiration and absolute exhaustion,

Lux Vaelthorn

Chief Financial Overlord of Hell

Department of Infernal Finance & Interrealm Asset Management

Vault Nexus Prime, Sector 7 – Lower Infernal District, adjacent to the Lake of Tax Auditors

(Author note: Are the bullet points intentional? Yes. I mentioned in Chapter 44 that Lux loves bullet points in his formal letter.)

’Nice. Send it.’

[Sent. Expect divine silence or flaming denial in 2-4 business eternities.]

Lux blinked once.

Then leaned back.

He felt a little better now.

Still bruised. Still thinking. But better.

"Hey," Rava said suddenly, drawing his attention.

He turned his head slightly.

"I forgot to ask," she continued. "Any color in mind for the car?"

Lux smirked.

"Something that looks like it belongs in a final boss cutscene."

She snorted. "So... matte black, probably illegal in three countries, and sounds like thunder when you start it?"

"Exactly."

She grinned at him.

Then hesitated.

"You want to go shopping alone?"

He studied her for a second.

Then nodded once. "Come with me."

And just like that—

The tension eased.

The mood shifted.

Even his smile was real now.
