Life in DXD

Tatsuya waited for there for a while sitting on one of the beds there which the vampire used to experiment on their test subjects.

He then looked at the bodies of the maou descendants and noted that the Leviathan took the longest to melt because of their affinity to water.

Valerie was listening to the tales of Tiamat and and Kurumi who were telling out their tales with the chest puffed up, since the young Damphir was looking at them with glittering eyes.

Tatsuya looked at the three of them who were sitting a bit away from him having their chat while eating something since Valerie was very hungry after the experiment.

Meanwhile Tatsuya was checking the situation with the other specially the ones that were left outside the castle dealing with the grunts.

Though he didn't need to worry that much since the holy sword users along with George were more than enough to deal with the enemies who were quite weak against holy element. The god killers, the Valkyrie and the heiress of Gremory too didn't have any problems as they just brute forced their way through them.

But still the most impressive was Isami who somehow unlocked the crimson queen mode and along with her dragon slayer magic and her sword was flying all around the field destroying the enemies without much problems.

Saji and Sairaorg also faced a lot of evil dragons on their way though they were more than enough for them as Tatsuya made sure to make Saji unlock his scale mail and Sairaorg was acting OP as always just punching the Dragons away. Regulus did the job of dealing with the vampires and devils not wanting to interfere with his king's fun.

Cao Cao and Loki were as expected making the things way difficult for their enemies as a fight against a god and the wielder of the strongest holy element weapon was way too much to deal against for the vampires and devils.

Though the thing that Tatsuya was most interested in was the fight against the grandpa and the grandson as Rizevim was like a typical villain was telling his plan to his grandson and both Vali and Bikou were listening to his plan with a serious look on their faces.

The fight between the two devils then started once the old man was done with his explanations and Bikou made sure that no body else interefered in their battle just as Vali told him to.

Rizevim, though had an advantage because of his sacred gear canceller, but Vali came prepared for that as Tatsuya had already warned him about it.

Black snake like projections started to come out of Vali's body as started wrap around him, that compared with his stats that improved alot by the training he did at Tatsuya's place along with the dragon gods made him stand just slightly below the super class devil.

Though Tatsuya was surprised that Ophis gave that much of her power to Vali, he also found out that it was just temporary and the power will fade away after a certain amount of time.

'So you decided to go with a temporary solution, huh. Pretty unexpected from Vali but still, a good method none the less.' thought Tatsuya.

Vali, then merged with the power as his armour appeared once again though it was the queen version of his sacred gear, the emperio juggernaut drive and not the diabolos dragon Lucifer form.

Rizevim was shocked seeing Vali able to use his sacred gear and tried again to use his sacred gear canceller, but the next instant Vali appeared in front of him and punched him through multiple walls and then started 'dividing' his power.

Once Rizevim's power started to divide Vali simply fired shit ton of demonic energy blasts at him without baby care as he was using his grandfather's power against him.

Rizevim too didn't held back and attacked Vali in return but Vali was easily able to doge those attacks or just simply divided them and added it to his own power.

Once he thought that the old man was weakened enough he came in front of him and said, "Just suffer till your death now." and released some of Albion's poison on the old devil and pushed the old man down and sat on top of him to not let him escape and squirm till death.

But still the old devil tried to kill his grandson with his power but his weakened self could not damage the armour even a bit and Vali just took out his phone and started recording the old man's death struggle.

In the end not being able to deal with his grandson, Rizevim pleaded to let him live But Vali just looked at him after ten whole minutes of pleading and asked, "Huh, were you saying anything?" making the old devil totally speechless at his words.

Seeing that the old devil was not saying anything, Vali just shrugged his shoulders and held his phone and searched up some "butts" to use them later at night.

Midway during is search the old devil died but that went unnoticed by Vali who was busy doing the 'research'.

It was until Bikou told him that everything was over that Vali realised that his grandfather died. He then deactivated his sacred gear and then made sure. to not even leave even a speck of the old devil's corpse.

Tatsuya who saw all that felt that everything was a bit anticlimactic, specially how Vali dealt with his grandfather. But just shrugged his shoulders and thought, 'Well, I am awesome, so it's natural that my presence will make some awesome changes as well.'

Tatsuya then contacted Vali and said, "Happy now, Butt dragon?"

"I am happy but don't use that title you ass hole." said Vali walking back towards the entrance.

"My grandfather is dead, so we can go back now. I will treat you all, so let's party once we go back." said Vali with an excited tone.

Tatsuya nodded his head and said, "That's fine but can you fetch the holy grail that Rizevim was in possession with for me. It must be somewhere around the room you just fought."

"Sure, what does it looks like?" asked Vali.

"Hmm, you can just feel the holy energy that the grail must be emitting and take it, right? It must be quite a powerful holy signature."

Vali and Bikou then stood at their spots and started searching for the holy signature of the grail but we're not able to find any signature except for the Cao Cao's sacred gear.

Tatsuya who heard that was confused and called Valerie towards him checked once again but still found that one of the grail were missing. Not knowing what was happening Tatsuya tried to connect the missing grail with the ones inside Valerie and called Vali again, "Is there a light glowing anywhere near you, I am trying to connect to the grail so it must be responding and glowing."

But still the answer was the same from Vali's end. Tatsuya who was confused by what was happening himself searched for the grail and found its signature I the dimensional gap.

Immediately his eyes widened and he heard a voice, "Ah, so Euclid-kun's theory was correct! Tatsuya Shiba does possess a mind reading ability, huh. Yahoo, am I audible?"

"Well, I really look at my 'prey' very carefully."

Tatsuya was shocked hearing these voices as he clearly heard and saw Rizevim and Euclid present in the dimensional gap with an army half the size of the ones present here.

"So as I told Vali earlier, let's start the plan." said Rizevim with a smile as he snapped his finger and Euclid started to break some seals.
