Three days into training, Ravel and I sat on chairs by a rocky outcrop, taking a break. I sipped tea from a thermos—delicious, perfect for my parched throat.

"How's your brother doing?" Ravel asked.

"Pretty good so far," I replied, glancing over.

In the distance—

"No time to rest, Raiser Phenex!" Tannin roared.

"Giving up already? We're just starting!" Tiamat added.

BOOM!

"GYAAA!" Raiser fled, chased by two Dragon Kings.

What a sight—two Demon Lord-tier dragons hounding him! His clothes were shredded, barely covering his lower half.

Reminds me of my summer training. My clothes were like that on day one.

"Difference is, you charged at them head-on. His reaction's more normal," Ddraig said.

What, I'm the weird one?

"Maybe."

Dodging the question, huh?

I'm resting now, but usually, I join Tannin and Tiamat in chasing Raiser. Intense training with a Heavenly Dragon and Dragon Kings, from morning to night, minus meal breaks. Post-training, Raiser collapses and sleeps like the dead. That's been the routine.

"He's complaining but doing the work. His attacks are getting sharper. Keep this up, and he'll pull through," I said.

"Really…" Ravel watched Raiser get blasted by Tannin's breath, worry in her eyes.

"Still worried?"

"Yes… I didn't expect Tannin-sama and Dragon King Tiamat to join you."

Fair. Two Dragon Kings is overkill for a high-class demon.

"Don't worry," I said calmly. "We're not reckless. We're holding back."

Proof? Raiser's still alive. If we went all out, he'd be done on day one. My Sacred Gear's offline, but Ddraig, Tannin, and Tiamat agree. We adjust to his level, though we push hard since he's immortal.

"It won't go too far. Trust me," I assured.

"If you say so, I'll believe you. Thank you for helping my brother," Ravel said.

"No prob. It's your request. I've got this."

"Oh, I made cake!" She placed a basket on the table, revealing small, tasty-looking pancakes.

"You made these? For me?"

"He's in your care… and I promised before."

Right, at that party. She actually did it.

"Try one?" she offered.

"Sure." I took a forkful. Soft texture, perfect sweetness. "Delicious! You're good at this."

"Of course! You're lucky to taste my pancakes. Be grateful!" she huffed.

"Haha…"

Classic tsundere. She's a good girl, though—haughty noble vibe, but pure and kind at heart. I savored the pancakes.

Oh, one thing I've been curious about. "Ravel, what year would you be in a human school?"

"Me? First-year high school in Japan."

"Really? My kouhai, then."

Same as Koneko and Gasper. She's… well-developed for a first-year. More than Asia, even. But Asia's still growing! Exciting times ahead!

Better not tell Alice. She'd cry.

"I want to try Kuoh Academy's uniform," Ravel said.

"Do it! It'll look great."

"Naturally! I'll rock it!"

Her confidence made me glance at her chest. Oops, reflex after that convo. Forgive me!

"May I visit your house again?" she asked.

"Anytime. You're welcome."

"Thank you! I'll come back!" She beamed.

Her smile's cute. Almost patted her head on instinct.

"By the way, Rias-sama and the others are coming tonight. There's a hot spring nearby," Ravel said.

"Hot spring!?"

News to me! Peeking plans activated!

No time to scout a spot with training. I'll wing it.

BOOM!

A huge quake and Raiser's scream. The mountain he was on? Gone.

"Is… is he okay?" Ravel asked, face twitching.

"Uh… he won't die… probably?"

BOOM!

Raiser flew through the air.

"Ease up a bit…" I said.

At my feet, Raiser smoked, charred, eyes rolled back.

Tiamat, unfazed, shrugged. "Oops. Used to sparring you. Misjudged."

"Come on…" I groaned.

I just told Ravel not to worry!

Tannin's used to training young dragons, so he's better at restraint. Tiamat? Maybe a mistake.

"What's up, Issei?" she asked.

"Just… this is tricky."

"What? Anyway, what about this bird?" She pointed at Raiser.

"Let's move him."

"I'll carry him." Tiamat grabbed his leg in her dragon form, dangling him.

…Like a chicken headed to slaughter.

Bit rough, no? At least grab both legs.

"Does it matter?" Ddraig said.

I ignored him and headed to the cave where Raiser and I slept.

Hours later, I left unconscious Raiser and flew to the hot spring. Peeking's a must!

Nursing Raiser? Nah! I tied him up tight with fireproof rope. No way he's crashing this.

"You're a demon," Ddraig said.

Only I get to see the girls naked! Anyone else tries, I'm a demon!

Per the local dragons' map, I was close. Then, a fast-moving presence approached. That aura…

"Red Dragon Emperor! You sneaking off to peek alone!?" Raiser roared, flame wings blazing, charging at me.

What!? I tied him up tight! He broke free!?

He screeched to a stop, pointing. "You won't hog the view! I'm peeking too!"

"You overheard me and Ravel!? Focus on training!"

"Shut up! I want to see Rias's breasts!" he yelled.

"What!?"

"I endured this training for this moment!"

He knew about the hot spring. Figured Rias would visit and bathe. Clever bastard.

"Take training seriously!" I snapped.

"I am! That's why I waited for this! I'll beat you and peek!"

WHOOSH!

His flames surged, hotter than ever—even more than our Rating Game.

"You've got some dirty guts!" I shouted.

Give me back my time!

"Shut up!" Raiser charged, flames blazing.

Why's he faster than in training!?

His fiery fist flew at me. "Take this!"

I dodged, landing a counter to his face. Normally, he'd be out.

But—

He tanked it, standing firm despite my fist sinking into his face. Then he countered, flames erupting, hurling massive fireballs.

I leapt back, dodging. Blood dripped from his nose, but his eyes burned.

He really wants to see Rias naked.

I'd do the same in his shoes.

I steadied myself, breathing deep. "Fine, Raiser, I respect it! You're as pervy as me! A true pervert!"

Red aura enveloped me, shaking the air. If he's serious, I'll match him. Some things a man's gotta do!

"Ultimate! Invincible! The mightiest dragon's power! Vanish!" I roared.

"Your power won't crush my dream!" he shot back, reversing our old Rating Game lines.

"What a sight," Ddraig muttered.

Ignore him! I'm defending the girls' honor! Raiser's not passing!

BOOM! BOOM!

Phoenix flames clashed with my red aura in the sky, trading blows relentlessly.

Ten minutes in, I was stunned. Despite my hits, Raiser wouldn't fall. Normally, breaking a Phenex's spirit works, but not now. His body was battered, yet his flames grew stronger with each regeneration.

What tenacity! His pervy guts are unreal!

"I'll… peek!" he panted.

Glancing back, I saw lights in the dark—too close to the hot spring. Any closer, and the girls might notice and leave.

Time to end this.

"Didn't expect you to be this tough. But you're done!" I reached into my pocket and tossed something at him.

"What!?" His eyes widened.

An ultra-lewd magazine, my finest pick. No man could resist!

Perfect for a perv-driven Raiser.

As expected, he froze. I didn't miss my chance.

Entering my zone, I roared, "Become a star!"

WHAM!

My kick sent him rocketing into the sky, twinkling like a star.

I exhaled, releasing my zone.

Immortal perverts are scary. Unbreakable.

Now, the path's clear. I grabbed the magazine and headed to the hot spring—an open-air bath, easy to peek into.

There! Rias and Akeno, naked! Everyone else, relaxing in the water. Perfect view!

Good thing I blasted Raiser. This is mine alone!

Wait… that rock outcrop ahead. Closer view from there.

I crept over, then—

"Oh…" I locked eyes with Miu.

Crap! Too focused to notice her!

"Big brother?" she called.

The others gathered. "Issei? Why're you here?" Rias asked.

"Issei-kun?" Akeno purred.

"You came too?" Asia said.

"Classic Issei, sneaking a peek," Xenovia noted.

Boobs everywhere! A parade of perfection!

"Issei-sama!?" Ravel's voice.

I turned—naked Ravel. Impressive chest.

Staring, nosebleeding, I was in awe.

"Issei… you… you!" Alice, red-faced, sparked with lightning.

Ravel's flame wings flared.

I'm dead.

"PERVERT!" Alice screamed.

"LEWD ISSEI-SAMA!" Ravel yelled.

ZAP! BOOM!

Their attacks charred me.

Days later, Raiser overcame his dragon phobia, regaining confidence from our rematch.

Guess perversion is power. Justice.

Next: the school trip arc!
