DxD: A World Where T*tties Defy Gravity [ Chapter 50: Impossible! ] (Patreon)

Rex took his sword away from Kiba's throat, and turned it back into a hairband, and tied his hair up again. He then offered his hand to the blonde wannabe-Casanova, and pulled him to his feet. 

Kiba, though he looked suspiciously at Rex, didn't look like he was going to pull out a sword and try to cut him up at a moment's notice.

"Anyway." Rex replied. "If I might make a suggestion, Kiba, why don't you try to put it behind you? I can't see being angry at the Holy Sword Project doing you any good."

"Why should I?" Kiba asked. "All it's done is cause me and my friends who died unending misery, and I-"

"Can't change it." Rex cut in. "If time travel was possible, which it isn't, I wouldn't recommend going back to stop yourself and your friends from dying at the hands of that Project. Not only would it probably break a fourth-dimensional law or twenty, just like going back in time to take the virginity of some- I dunno -some slutty present-MILF and father her child would, but that's beside the point."

Kiba was silent as Rex kept talking.

"Kiba, think for a second. When you died as a result of the Holy Sword Project, and died in the exact way you did, by presumably inhaling a dose of Zyklon B and/or chloroform into your system, what happened?"

"I... I was saved by Rias." Kiba replied. "She made me into her Knight."

"Indeed." Rex replied. "And has your experience as Rias' Knight been good or bad?"

"Good, definitely!" Kiba replied, slightly more defiantly than he would have liked. "I, the Sword of Rias Gremory, respect Rias and Mirajane as my King and Queen, respectively, along with seeing them as sisters I never had. Koneko, while a little closed-off from the world, is very nice, and a good friend, and Isane is quite nice. I can't imagine life without them, but, Rex… where are you going with this?"

"Well, let me ask you something else, Kiba." Rex replied. "Did you ever stop to think, even once, in the 20 years that have happened since the Holy Sword Project ended, that it was the catalyst that set off you getting reincarnated as a Devil, and meeting the people who you view as the siblings you never had? The people who, in your words, you can't imagine life without?"

"I..." Kiba looked down. "I never thought of it that way."

"Thought not." Rex replied. "So, Kiba, though I empathise with your anger at the Holy Sword Project, how about you channel your anger at it in a different direction? Like, I dunno, into trying to become as strong as you can possibly be, so you can be a better 'Sword of Rias Gremory'?"

Kiba looked thoughtful for a second, before adopting a resolute look on his face.

"I'll try." He replied.

"Good man." Rex replied. He created a sword out of the Primordial Power of Darkness. "Now that we've got that mushy shit out of the way, let's get back to training, Sword-Birther. I got a few ideas as to some special swords you can create."

"So, how's everyone's training going?" Palutena asked, as she sat down, a few feet away, and watched Rias and her peerage eat dinner or rather, a picnic-dinner, prepared by Akeno and Asia inside the dimension they were in. 

After the dinner, Rias and her peerage would have a mock-fight against each other for around half a week, before they went to bed. "What've you been doing for the past two months?"

"I've been doing magical training with Akeno." Rias replied. "She's helping me create a magical mine-field, with a combination of Power of Destruction and sleeping magic."

Rias' peerage gave small noises of interest through their food.

"Mira?" Palutena asked.

"Valian's helping me with my Sacred Gear." Mirajane replied. "She's been helping me with using my different forms of it, and helping me control myself while in said forms."

"...Akasha's been helping me with kicking in a fight." Koneko replied. "...She's considering teaching me savate."

"What's-" Isane asked, but Palutena answered the question of the current host of Ddraig before she could finish asking it.

"Martial art. Originated at around the beginning of the 19th century in France. Rex is exceptional at it."

"Oh." Isane replied, nodding.

"So, what have you two done for training?" Palutena asked, turning to Kiba and Isane. "My husband didn't carve you up into pieces, I see, Kiba."

"No, he didn't." Kiba replied. "He's actually been really nice. Rex' given me some ideas as to some new swords I can create with Sword Birth. Like a lightning-sword, one that controls gravity, and one that controls other swords."

"Cool." Palutena replied. "And Isane?"

"Tobio's been giving me some pointers in magic, and he's helping me with speed and stamina." Isane replied. "Even with those weights on, I feel a lot stronger."

"Well, when you take them off, on the day of the Rating Game with Riser, and after you win, you might have to work on restraining your newfound strength. I remember Rex not doing so, and well..." She shrugged. "I won't go into that."

Rias and her peerage continued eating their dinner for another five minutes, before Rias spoke up after finishing her sandwich.

"Speaking of Rex, Palutena, do you know where he might be?" Rias asked.

"Oh, Rex?" Palutena repeated. "He said he's going to see some friends of his. In the Grigori."

"The Grigori?" Rias blinked. "You mean the Fallen Angel organization that accounts for around 95% of all known Fallen Angels? Why would Rex associate with them?"

"What other Grigori do you think I refer to, Rias?" Palutena asked, slightly sarcastically and also slightly playfully. "And Rex would probably associate with them because their, arguably, highest-ranking female member is one of his wives, even if she is his first-cousin once removed."

Palutena took a bottle of Coca-Cola, opened it, and took a drink.
