Another day of training and planning

[A/N: Yo, some of you really wanted Issei to die, I do have a small plan for him but I haven't decided if I should carry on with it]

___________

<The great lake, Gremory territory>

"I've already been here a few times and I still can't believe how beautiful this place is" I said looking at the giant lake before me in all it's glory.

The great lake is about as big as the Caspian sea which is the largest lake on earth, even though it has the name sea in it, it's still a lake. It is said to be almost a mile deep.

I would one day like to split this lake in half, like how Moses split the red sea in the bible. Hmm...Sera-nee could probably do it.

.

"I know right, anyway, what are we doing today?" asked my crimson haired friend.

"You've seen Sona create those water spheres right, I want you to try and do that with your power of destruction, destroying anything inside. After you've done that try to see how much spheres you can make, also try and slow down or increase the sleed of destruction inside the sphere. It'll help you with control."

"Ohhhh!, that sounds cool, I believe I've seen Nii-sama use something like that before too" she said, nodding eagerly.

.

Yes, it's basically the move Sirzechs use to one shot Creuserey Asmodeus on the anime. I believe it was called rune of extinction.

.

"Me and Sona will be doing what she said we'd do yesterday, learning our capacity and control"

"We should also see how much water we can make, before we tire ourselves out." Sona added.

I nodded, that is indeed a good idea.

"That's the basic plan until lunch break"

.

And so begins another day of training.

To test just how much water I can control I decided to make a giant snake out of water and just try and make it as long as possible.

While Sona, well she's creating what seems to be a whale or is that a blimp I don't even know, mine looks cooler anyway.

"This is harder than it seems" Rias' mumbled pulling me out of my thoughts.

Hmm, so she can already make multiple spheres, but has trouble in making mutiple of them big enough to fit the trees.

She could make one giant sphere but that wouldn't always do, especially in a fight where allies would be present here and there.

But all in all, this is great, I didn't think she'd get this far, it's already alot more than I had hope for today.

The things they did the last two weeks are stuff they should be only be able to do after a few years if they weren't training, I really am just speeding things up.

...

(Few hours later)

"You three are surely working hard"

Well this is a surprise.

"Nii-sama!! what are you doing here?"

"Just looking to see what the cutest little sister in the world and her friends are doing" he said fawning over his sister.

Wow...

Also Sera-nee would definitely disagree on that.

"Good to see you again Lucifer-sama" Sona and I called out.

*sigh* "How many times do I need to tell you two that you don't need to call me that unless on formal gatherings" he said shaking his head.

"I can't, it's disrespectful" Sona replied bluntly. I nodded as well, but I'm just doing it to annoy him, which I have absolutely no reason to expect because I can.

"Nevermind" he said gloomily. "Anyway, how's it going with this training of yours?" he decided to ask.

"It's going GREAT! It's can be a bit tiring but it's also very fun" Rias replied cheerfully.

Good to know she's having fun.

"So, what's the real reason you're here Lucifer-sama?" Sona asked.

"It's really nothing, I have a meeting to attend in Lucifeed with the council, but I decided to vist you guys first instead." he said with a smile as he continued to give Rias headpats. I should also do that more often, she seems to like it.

"Shouldn't you hurry on then?" Sona said bluntly.

Geez Sona, if I didn't know who you are I'd immediately assume you don't want him here.

"Nah, I can just teleport there on the last minute, as long as I'm not late it's fine"

"Nii-sama you really should take your work more seriously" Rias my dear, that's probably never gonna happen.

"Like I said It fi-"

"Sirzechs-sama, so this is where you are" said a sickeningly sweet voice of one of the strongest female in the underworld. AKA Grayfia.

"Umm, he-hehello my dear?" Sirzechs choked out.

"Forgive for the intrusion, but I'll be taking Sirzechs-sama back. He has a meeting to attend after all" she said pulling him by the ear and immediately teleporting away.

...

"Well that just happened"

*Sigh*"Why are the current Satans such a weird bunch" Rias said in a somewhat amused tone.

Wow, she just called her brother, her two bestfriend's sister and father weird in front of them and it seems me and Sona completely agrees with her.

"What do you mean, Sera-nee isn't weird" I defended my favorite magical girl.

"But you agree your dad is weird?" ask Sona who looks at me weirdly.

"Yes" I answered immediately with a straight face. [A/N: TBH Ajuka might be the most normal of the four]

"Let's just eat lunch" Rias interjected clearly not wanting to see me argue about the superiority of Sera-nee, and so we did.

.

.

"You two are planning on travelling around the human world after you get your evil pieces right?"

"I plan to do so, we have six years before we're required to go to high school in Kuoh Academy. I'll take it slow and travel for a few months come home and do the same the following year and so on."

"I see. How bout you Sona?"

"I too will, and I'll be sticking to Japan, to get use to it since that's where we'll be working for the foreseeable future. How about you, are you planning as well?" Sona said and asked.

"I do, I have a few plans for Japan, Britain and Romania"

"OH! I also have plans to visit Romania someday, along with Japan and Italy" Rias chimed in.

Hmm, so Akeno in Japan, Kiba in Italy and Casper in Romania. Ok, I need to join Rias to Romania since I don't know when exactly she found Casper.

"That's GREAT! maybe we can travel together" I suggested.

"YEA! that would be perfect" she nodded happily.

"We'll go whenever you plan to go" I said and she nodded still smiling.

Good, I'm one step closer one of my bishop candidate.

[A/N: At this point, it's really obvious who it is]

"Alright, let's continue our training shall we"

They nodded and we continue training for the rest of the day.

Rias continue doing what she was doing before while Sona and I are decided to practice against each other, by using and controlling water balls to try and hit me while I use Bonnie and Clyde to destroy said water balls while flying around.

'These two sure are resilient and hardworking. At the rate we're going I have no doubt by the time Kokabiel pops either one of them would be able to deal with him easily even without the help of their peerage. And they'll only grow stronger from then on' I thought to myself. I thought as I continue to dodge and shoot.

[A/N: I'm not gonna do something like make them Ultimate class devil just from a year of training or something like that. Gotta make it somewhat realistic]

And just like that the day went without a hitch and another day of training finally came to an end.
