Rias also taught Kuroha plenty more—like how to sprout wings.
When a pair unfurled behind him, he marveled at first, but quickly retracted them.
Felt kinda weird having wings.
Beyond that, she mentioned something that piqued his interest.
"Devils have ranks too. Many like me are born into noble houses with titles from the start, but some rise from nothing to earn them. Reincarnated ones like you can claim titles too~"
"Then I can get servants with a title?"
"Exactly."
"So to peerage someone like you, Rias-senpai—what rank?"
Rias blinked in shock, then burst out laughing.
She booped his forehead lightly.
"That'd take becoming a king."
She meant it as a joke.
But Kuroha bowed his head, murmuring.
"King, huh... I'll do my best."
Rias watched him ponder, eyes narrowing with quiet delight.
Maybe he really could...
They talked late; exhaustion hit her. She stretched languidly.
"Bedtime—school tomorrow."
With that, she claimed the bed's inner side, eyeing him.
Kuroha's mouth twitched.
"Rias-senpai... you're sleeping here?"
She pouted pitifully.
"What, Kuroha—don't want me?"
"N-No..."
Her face lit up brilliantly, arms open.
"Then come—pillow anywhere?"
Eyes twinkling, she licked her lips seductively.
"If you can't hold back... I'll help~"
Kuroha gulped. Devil... pure Devil...
Resolve hardened in his gaze.
He obeyed.
Her captivating scent lulled him into deep, dreamless sleep—no Yuma nightmares. Peaceful.
Or not—some sweet, comfy dream he never wanted to wake from.
Until a surging urge hit. Eyes fluttering open to...
Blackness.
He sniffed lightly.
Rias-senpai's scent.
"Mm... Kuroha, you're naughty~"
The darkness pulled back, revealing... round... hips??
"Rias-senpai! What're you doing?!"
No clue what happened, but something definitely did!
She turned, swallowing visibly, wiping her mouth daintily.
"Nothing—saw you raring to go this morning, helped out..."
Kuroha glowered.
"Rias-senpai..."
"What...?"
His expression spooked her oddly.
But next instant—tears streamed down his face.
"Next time... when I'm awake, please... waaah..."
Rias fumbled for words, sighing helplessly.
Long road ahead.
Kuroha's mind was pure ecchi now.
How to fix this?
Routine school run, but he'd adapted to the jealous stares.
Rias-senpai endured worse daily. Habit numbed it—mental fortitude.
At the entrance, bag in hand, she smiled.
"See you after school~"
"Y-Yeah."
Kuroha dazed at the scene.
Like... a couple in love.
Gonna die!!!
Ack!!! Who's choking me?!
"Damn you—how're you so close to Rias-senpai? Die!"
No dream—strangling him: Matsuda and Motohama, eyes burning envy.
Kuroha slapped at Matsuda's hands, pleading.
"Really... dying..."
Matsuda released grudgingly, glaring at the gasping Kuroha.
"Why you walking with her? Too jealous-making..."
Kuroha caught his breath, stood proudly, patting their shoulders.
"We're different. I... evolved."
"Die!"
Nights after, Kuroha biked with flyer stacks to marked spots, delivering.
Flyers: simple summons. Strong desire + wish = Devil appearance.
You wish, I claim price, grant it.
Simple.
He'd looped this nightly. Normally Rias-senpai's familiars (humanoid) handled it.
But she said it built familiarity—like Koneko and Akeno did.
So he dove in eagerly.
Per her, though—contracts were scarce lately. Life-risking wishes.
Even those collapsed over unacceptable prices.
Her take: one cool line.
"Human value isn't equal."
Brutal—ranks lives nine ways from Sunday.
Days in, he noticed: red dots never vanished. Some repeat visits.
Diverse desires?
Some summon once... then twice, thrice, lifelong?
Humans full of emotions—desire destructive?
Kuroha puzzled.
Then it hit.
Only ecchi reigns supreme!
My desire's pure: ecchi with Rias-senpai.
Heh heh heh...
Sleazy grin and drool crept unbidden.
Meanwhile, sensing it, Rias smiled wryly.
"Kuroha... never lets up..."
Akeno, attending her, chuckled.
"Isn't that good? Lively vibe here."
"Yeah..."
