( Yuuki's POV )
With the help of Matsu and Regina, I finished all the weapons and armor I was working on, the girls spent a few days training with them, and since Regina had already invented a prototype engine that ran on mana, I also finished the motorcycle and other vehicles I was working on.
We were thinking of visiting a new kingdom to look for the reincarnated one in this world but before we decided where to go, Leen appeared excited that she had found another mysterious ruin south of Mismide past the sea of trees in the desert of the Sandora kingdom, Regina refused to answer when Leen asked if that was the library but even if it wasn't we were going to go there, We were traveling in the sky garden and along the way I decided on my new project, like in any good jrpg when you need to travel to distant kingdoms you use a flying ship, I can also create small flying ships to give to the kingdoms of Belfast and Mismide.
While we were flying through the desert the sky garden detected something and then a screen appeared showing us a phrase in the shape of a stingray chasing a group of humans.
Yuuki: Perfect, Regina now we can try that.
Regina handed me some crystal prisms, a Mana traps, these little things could contain the phrase cores and block the outside mana to prevent them from regenerating, I was about to jump into action but Leo stopped me.
Leo: wait Yuuki, leave this to us, you take care of the rescue.
Yuuki: ...I guess that's for the best.
This time Leo and her retainers were going to have all the fun, I teleported together with Elze in front of those who were being chased by the phrase and we created a large hexagonal barrier to block a shower of crystals that Phrase used to attack, I modified the barriers that way to be more useful with our fighting style, girls who focused on long-range combat still used the previous barrier style.
Yuuki: Are you okay there?
The group that was escaping from the phrase was a team of three adventurers and a group of girls being escorted by them, When they recovered from the surprise of our appearance, an adventurer approached us.
Adventurer: we are fine thanks to you, but who are you?
Yuuki: Just a group of adventurers on a family trip, let's move to a safer place.
After moving everyone to a safe place I jumped on a large rock and watched the girls take care of the phrase, Barghest had a full body armor made with my scales, mithril, and phrasium, The crystal that formed the Phrases' bodies, that armor was almost indestructible and could absorb some magical attacks.
Barghest jumped from the sky garden and fell like a meteor in the phrase and it crashed on the ground cracking its entire body, She took flight again and tried to regenerate but Leo didn't let her, she had greaves and boots that combined wind and gravity Materia that allowed air walking, Elze also had the same pair, she used that combined with [accel] to get close and break Phrase's body with a mithril Buster sword, Yukikaze had a short range teleportation Materia when the cores were exposed she used mana traps on them, ending the fight.
Ende: oh that was awesome.
While I was watching the fight the mysterious world traveler, Ende, appeared next to me.
Yuuki: Ende? What are you doing here?
Ende: I felt Phrase's presence and came to take care of him but it seems that you have everything under control.
Yuuki: You can feel them, tell me, do the phrases come from your world?
Ende: ...I am surprised that you can say that I am not from this world.
Yuuki: well I am a fellow world traveler, answer my question.
Ende: No, they don't come from my world.
Yuuki: Is the appearance of the phrases a natural phenomenon or are they looking for something?
Ende: They are looking for someone, I can't say more than that.
Yuuki: so you are an enemy of this world?
Ende: ...No.
The last thing he said wasn't a lie but it wasn't true either.
Yuuki: *sigh* this is about a woman, isn't it?
Ende: how-
Yuuki: I may be in a situation similar to yours, you don't have to tell me everything but I won't let anything hurt my family, I will destroy any phrase in this world.
Ende: That's fine, that way I can concentrate on my mission, see you later Yuuki.
When Ende disappeared I met with the group of adventurers to hear their story, they rescued a group of slaves, all of them women, Since their master had died they wanted to take them to a safe place, they had slavery collars linked with magic, very difficult to remove, As long as they had those collars they would never be free in Sandora's kingdom.
Hearing their predicament, Yumina and I took care of business, I removed all the necklaces with transmutation and opened a portal to our mansion, Yumina told them that the kingdom of Belfast would welcome them with open arms, we would check on them later but for now we continue with our search, and when I went to the sky garden I gave the cores to Regina.
Regina: I can't wait to experiment with this, thanks honey.
Upon receiving the cores she leaned forward and gave me a deep kiss, That surprised me but not as much as when wings of light appeared on her back, It seems that she went through the process of becoming Sekirei without telling me when the kiss ended she lowered part of her lab coat and showed me her shoulder with the number 43, Then I looked at all the girls and the only one who seemed a little upset was Leen, it seems that they had already accepted her into the family, if they agree that is enough for me, I like Regina after all maybe I have a thing for perverted geniuses.
After that we soon found a suspicious sand dome and after Leen used some wind magic, a metal dome was revealed.
Yuuki: How am I going to get in?
Regina: Just walk forward, and you'll go through the wall.
Yuuki: you're not coming?
Regina: It's better if you go alone, but I could accompany you if you give me something in return.
I could feel Leen glaring at me so I decided to go alone, I went through the wall like Regina said and could see the familiar transport platform and after a flash, I was transported to another part of Babylon.
