DxD: Reincarnated Trickster in Ecchi World

"S-Senpai-"

"I know, Ise," I said quickly, understanding his concerns over the dreadful situation but… feeling quite ready to face someone of his caliber, especially with what I had planned to do with one of those Fallen Angels.

"But I have a plan."

It's all for science, after all!

The middle-aged man chuckled at my confident words.

"'A plan'? Do you seriously think anything you could come up with would work on me?" He pressed on with a mocking tone, ready to deride the 'sorry state' we were going to be if we didn't react properly to him.

But I just gave him a wide smile.

"I can assure you, prick, that my plan is the best plan possible and you should have expected guests."

My finger pointed right behind him and he turned to look, trying to find any intruders he had not detected and…

…

There was no one.

He turned around out of instinct, mouth hanging open and ready to call out my 'silly' bluff but he stopped at what I was trying to pull here in this deadly circumstance.

Pumping energy into my lower limbs the very moment he had turned around to play with my trick, I grabbed Issei close and turned around myself, legs moving quickly and swiftly as I muttered a grand hero's true strategy out-loud.

"Nigerundayo, Ise!"

…

"WHAT?" The brunet yelled under my arm, squirming a little as I rushed deeper into the foliage.

"You little shits!" Dohnaseek yelled furiously.

The Fallen Angel looked absolutely pissed and tried to get himself flying to try and intercept us from getting too far but-

BAM

-he ended up slamming on some tree branches in the supposedly simple process.

Face bleeding from the impact and his logic vanished because of the humiliation and the injury he had sustained, the Fallen Angel didn't stop in his pursuit and continued to give chase despite his new wound.

I sighed at his persistence and I decided that the distance we got over him was enough to start laying down a new plan.

Turning some of the corners through the trees, I jumped on a bush, Issei yelping as he took most of the fall damage in the process.

I was still human, and that kind of hit wasn't meant to be worrying to a Devil, even a new one as Issei.

"S-Senpai, what are you-"

"Be quiet, Ise." I stated with a stern tone, my hands glowing as I started to place some magical signs all over the trees...

"Now, this is my real plan."

The lights coming from the seals softened to a calm hue, and soon disappeared as nothing had happened there.

"Now you stay here as I deal with this annoyance, okay?"

"S-Senpai, don't-"

But despite his best attempt to keep me from leaving the hideout, I yawned as I walked on the clearing and waited to be spotted by the Fallen Angel.

"There you are!"

Launching in a burst of speed, the middle-aged man gave off an animalistic glare, akin to a predator finally catching its prey and then-

WHIP

Eyes widening, Dohnaseek dropped the Light Spear he had created while rushing towards me, several silver-colored strings keeping him stuck still mid-air.

"For being someone that pride himself as one of the 'strongest' Fallen Angels, you sure suck in keeping yourself out of an ambush, Dohnaseek-san," I hummed quietly, my silky voice latching at my words.

He tensed at his real name being mentioned. "Y-You bastard-UGH!" The strings started to squeeze at him and I sighed.

"To think that a simple spell like the 'Silver Lining' could give you this much trouble and…" I crouched to pick the still-present Spear, humming at its magical composition. "What an interesting conjuration we have here."

"You pitiful human! Once your Magical Core go empty, your life is forfei- STAB -!"

The previously clean spear was now stained with his blood, the man looking down as I continued to push it deeper inside his torso.

Trembling in pain and fear, the Fallen Angel seemed to have understood that this wasn't going to be a warning for his group, that I wasn't going to let him free.

There wouldn't be any warning for soon-to-be terrorists.

I sighed again this time showing a curt smile at the dying man.

"Your little rebellion is going to end very soon," He tensed up in panic at my words. "Kokabiel isn't the sharpest planner, isn't he?"

His eyes widened even more at the mentioning of his boss, but his attention was mostly diverted in trying to live through the painful experience but-

STAB

The spear was pulled out almost instantly and pushed once more in his body, the damaged part this time being… his heart.

There was an instance of inner realization that his life was slowly going out and slowly he slouched over the strings of platinum grasping over his dying body.

I waited a few more moments of silence before pulling the spear out one last time, letting the weapon collapse and release its energy.

But instead of letting the energy disperse as usual, I decided to let it seep in my reserves for further study about this kind of magic.

"S-Senpai?!"

I blinked and turned around to see a shell-shocked Issei, glancing back and forth between me and the now-death Dohnaseek.

"I will explain what is going on tomorrow, Ise," I assured without leaving much room for protests and patted his shoulders as I went towards him.

He looked confused, frightened even at the scene I left behind as the strings finally faded away, letting the man's corpse hit the ground.

"Right now, you should back to the fountain. I think Rias-san should be there and… Do keep quiet about my little stunt here, okay?" I asked him quietly while squeezing his shoulders again.

"I am serious, do try and keep quiet about what has happened here, say that you managed to out-run the Fallen Angel and… I will be thankful."

He relaxed a little, his shoulders sagging as he nodded at my request. "B-But why are-"
