( Yuuki's POV )
Although somewhat surprised I invited Xenovia inside, after the way they left I didn't expect that she would come back and ask to join my side.
Yuuki: I am going to reject someone talented like you but could you tell me why the sudden decision.
Xenovia: Well, I no longer feel that the church is the place where I belong and I believe that here I can find that again.
Yuuki: That's fine with me, but you know what our main goal is.
Xenovia: Yes, that woman Ana talked to me and Irina about that the other night, I think that will help me find what she was looking for.
Yuuki: say no more, just a warning training is going to be much harder than before.
Xenovia: I didn't expect anything less from you.
Xenovia didn't have many belongings so when the young devils finished their preparations we returned to Babylon Castle, I let my maid take care of our guests while I moved to the back of the castle where the girls were training, Since Xenovia had nothing to move to her new room, she followed me.
Xenovia: wow, what is this place?
Yuuki: That's the recently built Babylon Coliseum.
To make the test of breaking more limits safer we built a coliseum around our special training ground, With that we could control everything that happened within its perimeter, such as terrain, weather, gravity, and all that, I entered the spectator stands and there I found Ravel and Eu watching the rest of the girls train, Eu noticed my presence immediately but Ravel had no idea so I crept closer to them and kissed the top of their heads.
Yuuki: hey I'm back.
Eu: um... Welcome back.
Ravel blushed at my gesture, while Eu gave me a cold welcome but I could feel the strong feelings in her words, I sat next to the two of them and watched the training.
The methods they were using were different from normal, they were not fighting hollow dragon armor, They were fighting in groups of one against Ten and there was a rotation of those who fought against the groups of ten, I guess they were the ones closest to breaking their limits.
Ravel: ehem Yuuki, are you sure it's a good idea to have a guy like him join our group?
Ravel pointed me to Kokabiel who was training together with the girls, Those who come from his world have their doubts about that guy but I was sure that the atmosphere of our family would rub off on him quickly.
Yuuki: Don't worry, he will be another member of the family in no time.
As I looked at the girls I was surprised at how strong they had become since the last time I saw them, they were very serious about accompanying me this time, I had no doubts that Tsukiumi would cross over to the next level, she is the strongest Sekirei after all but I was surprised at everyone who was approaching her level.
When the training was over and the girls noticed I was there, Chiho and Saya-shi took me aside to talk about all the monsters they had tamed, We moved to the floating island where the habitat they managed was, and when we got there a bunch of monsters ran towards the girls and rubbed their heads against them, it was a quite a sight all those monsters acting as their pets.
Saya-shi: What do you think, very impressive eh.
Yuuki: It really is.
Chiho: Leen told us that we could form pacts with these creatures to increase their powers, as if they were summoned creatures.
Yuuki: That sounds perfect, you already have everything prepared.
Chiho: of course!
I spent some time helping the girls with their preparations for the pacts with the tamed monsters but as always there was something on my agenda and immediately after that I was called by Regina why that pale girl we had rescued had woken up, again.
////////////////////
Regina: just as I thought, you gave her too much of your blood.
The moment I arrived Regina tried to blame me, because she wasn't specific, about the amount of blood I should have given to the girl we saved but I stayed calm and tried to move past that.
Yuuki: ...Is she okay?
Regina: oh she's perfectly fine, she regained her senses and I even talked to her a little.
Yuuki: then, why are you saying that I gave her too much blood?
Regina: It's because your blood not only fixed her aggressive behavior, but she received a bit of your powers, specifically she can stop time around her for a short moment.
Yuuki: are you serious?
Regina: You hear those kinds of stories all the time, of warriors who consume dragon meat and bathe in their blood to gain incredible powers, The point is that you must be careful who you give your blood to, you must not let anyone take it.
Yuuki: Thanks, I'll be careful with that.
Regina: see that you do, of course that doesn't apply to your lovely fiancée who might want to experiment a little with it~
Yuuki: Go ahead take what you want, I also want to experiment a little.
Regina: thank you darling~
Yuuki: but first back to the girl, did you say you talked to her?
Regina: yep, she said her name is Sakuya, I asked her about the world she comes from but she said she doesn't remember much.
Yuuki: maybe there isn't much good to remember, her world must be infested with those gray zombies.
Regina: She called those things kabanes and I think you're right.
Yuuki: well you already created a cure so we should search their world and give them a hand.
Regina: I will inform Matsu.
