DXD: Hard To Kill

As the albino-haired shinigami from another world cut down the human magician of chaos brigade, he stopped all movements the moment he heard something he didn't expect to still hear in another world.

[DING.... 27921 EXP gained]

[LEVEL UP] [LEVEL UP]

The air around the otherworldly Shiro changed as his eyes became blank. The human magicians of chaos brigade felt a cold chill run down the back of their spine as a glint finally appeared in his eyes and he yelled.

"EXPERIENCE!!!!" he roared as he charged into the fray with a look of hunger on his visage

Watching his counterpart run around in a frenzy spewing profanities and words such as 'Killsteal' or 'experience' along with maniacal laughter, the silver eyed crimsonette opted to ignore it and turn to his parents.

"Hi mom, hey dad" he greeted his parents as he heard the sound of his student dragon emperor form a crater on the ground.

"I thought you said you did not wish to attend the summit." His mother stated as he did remember refusing the invitation

"I just didn't want to show up for the boring meeting, this on the other hand is so much more interesting" Shiro clarified

"By the way dad. Why are we just letting Issei fight Vali by himself when we have some of the strongest beings of the three factions?" he asked unsure of why they were literally doing nothing as everyone else was fighting. Seriously just one of them could probobly take care of this invasion.

The aforementioned father just put his hand on his child's shoulder.

"Because it's romantic!" he said with stars in his eyes dumbfounding the shinigami

"Romantic?" Shiro repeated to his father

"Two rivals that have fought each other for centuries! It is the pinnacle of a man's romance! Can you not see Aversis? If we were to interfere then that would be just rude!" the crimson haired satan exclaimed as his son just dumbly nodded

"Enough about your father's delusions of grandeur. What's this I hear about you causing trouble in India?" His mother asked sternly as her gaze sharpened causing the shinigami to back off a step.

He snapped his head towards the magical girl with a look of betrayal

"You bitch!" he said pointing at the Leviathan

"That's what you get Shiro-tan. Do you know the amount of paperwork I had to do because of your mess!?" the female Devil King said as she stuck out her tongue towards the shinigami

Shiro turned his gaze towards Kuroka with eyes pleading to save him but she was already next to her sister as she ignored his plight. Luckily he was saved by a certain vanishing dragon when he heard

[HALF DIMENSION!] came the voice of what he assumed was Albion

Everything in the space near Vali started to become smaller. The shinigami could feel something was trying to affect him but failing.

"He is warping the dimensions, it is extremely dangerous" stated the arch-angel

"That isn't fair!" Rias said as she watched the school shrink

"Of course it isn't whenever there are dragons around." Azazel said not really fazed by the situation as he smirked

"Let's add something else unfair to this then" he continued as he looked over the future harem king

"Hey Red Dragon Emperor! Hyodo Issei." the fallen governor called out

Turning his attention "What do you want?" Issei asked as he tried to think of a way to stop his rival

The smile never left the fallen "Let me explain this to you simply, so even you can understand" Azazel said as he began to explain

"That power halves things around it. Which means.... Rias Gremory's bust will also become half size" he finished clarifying as the red dragon emperor seemed to go into a trance muttering things about 'Oppai' and 'halved'

Shiro felt the air change as he looked towards his student snapping

"DON'T F.U.C.K WITH ME!!"

[BOOST] came the voice of Draig as bursts of energy broke around the red dragon emperor. Strangely enough Shiro noticed the boost didn't actually affect Issei. The shinigami's mouth hanged open the moment he saw his student raising something up to point at his enemy.

"Is that my fish?" the silver eyed crimsonette blurted out as he wasn't sure when the Dragon Emperor took his fish

"YOU SAY YOU'RE GOING TO HALVE MY BUCHOU'S OPPAI!?" he exclaimed

"What?" dumbly questioned the vanishing dragon as he looked at the giant bass in his rival's hand begin to glow red and gold

"I WON'T FORGIVE YOU!" [BOOST] "YOU'RE THE ONLY ONE I WILL NEVER FORGIVE VALI!"

[BOOST!] [BOOST!] [BOOST!] [BOOST!] [BOOST!] the sound of continuous boosts went on as everyone looked in awe at the aura the fish gave out

"What the hell is he doing to my fish!?" Shiro cried

[System detects the fish's holy attribute being boosted] rang out the sound of the system

'System where did you get that fish? And why does it have a holy attribute?' he asked the system dumbly

[The bass is a regular fish, however it has lived within Avalon soaking in the environment around it. System detects Holy attribute equivalent to the real Excalibur after boosts and still increasing] the system clarified to the dumbfounded shinigami. In hindsight he probobly should have suspected something when the fish didn't break on impact with an ultimate class devil.

"Hahaha, his power is increasing exponentially just to keep his master's b.r.e.a.s.t from getting smaller?" the fallen governor laughed as he put up a barrier

The red dragon emperor held up the giant bass as a red avatar of it continued to enlarge sending out waves of holy energy. "Just try to lay a finger on Rias Gremory you bastard!" Issei roared as the energy from the fish reached it's height

"I'LL DESTROY YOU SO COMPLETELY, YOU'LL NEVER BE ABLE TO REINCARNATE AGAIN, VALI!"the future harem king declared as he pulled the fish back and yelled the first words that came to his mind.

"FISH...CALIBURRRR!!!" he yelled bringing down the giant bass as red gold light destroyed the vanishing dragon's armor sending him flying out of the barrier

Everyone just kept staring with open mouths at the power of the giant fish that could be on par with legendary weapons.

"I don't know whether to be proud or pissed" the crimsonette spoke up as he was deciding whether to be proud since Issei was his student or mad at the fact that he pulled something off more ridiculous than himself

∞

Teleporting to his house with his nekoshou lover after escaping the aftermath, the two dumbly looked at the giant missing land infront of them where their house was supposed to be.

The shinigami took a deep breath and threw up his hands

"MY HOUSE!!!"

his cry woke up all the neighbors
