( Yuuki's POV )
After the dark portals disappeared, we dealt with the rest of the enemies really quickly, In fact, repairing the damage to the surroundings of the mansion took us longer.
This battle produced an unexpectedly good harvest, obviously another marble of power from the reincarnated one but also, Two of the reincarnated man's lackeys had sacred gears, these were common sacred gears but that didn't matter to me, I can finally tinker with a sacred gear.
About the monsters we captured, these were seventeen different species that we left in a special place within Kouten, I need to create a special habitat for all of them and for those we had to kill, their parts will be used to make weapons.
Regina took several of the gray undead to analyze and we burned all the rest.
After all that I met with Sirzechs to discuss our situation, As we had agreed, the punishment of the now former Lord Phenex was left to the devils and he was taken to another place by Grayfia.
Sirzechs: I must say, Yuuki that was an impressive display of power, everyone in your faction is something else.
Yuuki: You flatter us too much, I would have liked to see a demon king in action.
Sirzechs: On another occasion maybe, I'm curious, you three are world travelers, how come you are so stronger than them?
Yuuki: We have different experiences and powers, those two were working together because their powers could complement each other, it would have been more difficult if they had fought together.
Sirzechs: I think you're right, what are you going to do now?
Yuuki: After this fight, I have many things to take care of and I will have to return to my world for a few days but if there is an emergency, do not hesitate to call me.
I gave him one of the phones that can communicate between worlds and with the permanent portal in the mansion, so there was no problem there.
Sirzechs: I'll keep that in mind, you're going to take the Phenex lady and daughter with you, aren't you?
Yuuki: They asked me, I guess they are not very happy with the idea of continuing to live in that mansion, What happened to them is partly my fault so I plan to support the Phenex family however I can.
Sirzechs: If it's not too much to ask, could you also take Rias and the others with you?
Yuuki: that's not a problem, but why do you want that?
Sirzechs: They have grown a lot in a couple of days with you, I would like you to continue training them.
Yuuki: of course, like I said that won't be a problem.
////////////////////
Yuuki: Welcome to the Babylon kingdom!
When we left the Underworld I transported us all to our world, right outside the palace so that they could appreciate it at the same time as the city.
Issei: is that a mech?
At the entrance of the palace, there were always two frame gears standing guard, and that attracted the attention of Issei and Saji.
Yuuki: Yes, those are called frame gear.
Saji: Can we ride one of those, please!
Sona: Saji no, we are guests here, don't cause problems.
Yuuki: That's not a problem, if you want, you can pilot one of them later, but first you should relax, walk around the city, everything will be up to me, Afterwards we will have a feast and tomorrow we will resume training.
I asked my maids to be in charge of guiding the devils during their stay and then I moved to my lab, Regina and Matsu were going to investigate the bodies of the undead and all the monsters we captured, When I searched the body of the reincarnated one I found a book with important information about all the monsters, making it easier to create a habitat for them.
When I started experimenting with sacred gears, I found some obvious similarities with Ranko's [Persona] ability, my head was filled with ideas, and in the end, I called her to help me, but when she arrived she was not very enthusiastic.
Ranko: You know Yuuki, I'm not very good at creating things, I don't think I'll be able to help much.
Yuuki: Let me worry about the technical things, I want to ping-pong some ideas with you, this is your power so you should understand it on a deeper level.
Ranko: oh yeah, I can do that.
We argued until lunchtime arrived and when I returned to the mansion I met Lady Phenex, who had a serious expression.
Lady Phenex: Yuuki, I can talk to you about something, it's important.
Yuuki: of course, is there a problem?
Lady Phenex: No problem, I want to ask you to take my daughter Ravel as your fiancée.
Yuuki: I didn't expect that, what brought this on?
Lady Phenex: Recent events have left my family in a delicate situation.
Yuuki: I plan to support your family, going that far is not necessary.
Lady Phenex: I'm looking out for her, right now if any noble family asked for her hand, I couldn't do anything.
Yuuki: and an engagement with me will prevent that.
Lady Phenex: it is the best option, I know that she cares about you and I know that you will treat her right.
Yuuki: well, I'll have to talk to the rest of the girls.
Dama Phenex: Oh, I already talked to them, and they approved of the idea.
That basically means that it's already decided, I approached the Phenex lady staring at her and I took both of her hands.
Yuuki: I understand, I promise you, I will take care of your daughter.
Lady Phenex: I know you will.
We moved to the dining room and while we were eating I kept looking at Ravel but when she looked at me she blushed and quickly moved her gaze, I think the girls talked to her before I could, honestly that wouldn't surprise me.
After that I tried to talk to Ravel alone, When I approached she seemed happy but when I started talking she got too nervous and she ran to her room before I could say what I wanted to say.
Since my matter with Ravel was postponed, I returned to my room and started planning training for tomorrow, It was time for me to concentrate on the specialties of the young devils.
