(After the events of Elfen lied)

It all starts just as the anime ends, everyone is having lunch, Nana is really enjoying dinner and Kouta, I was thinking about what happened, when suddenly, Wanta, Mayu's puppy, starts barking, when he saw what was happening, he saw that there was A strange woman in front of his door, the sun did not let him see her very well, to which Kouta asked out loud about her.

Kouta: Hello? Who are you? Sorry, this is no longer a store!

?: I don't come for any of that.

Kouta: Huh?

?: You are kouta, right?

Kouta: Ah, yes, that's me.

The mysterious woman had a somewhat elegant and cold voice, she heard a sigh.

?: You can open the door?

Kouta:...

The others noticed the girl's presence, Nana felt a sense of mystery and went to see what was happening.

Nana: What's going on here?

Nana, upon seeing the woman, her feeling of mystery changed to distrust, so she activated her vectors and approached the woman. Kouta, noticing that, tried to stop Nana.

Nana: Who are you and what do you want?!

Kouta: Nana wait!

?:...I see that they leave me no choice.

The mysterious woman raised her hand, forcing the door open, but without hurting anyone, Mayu and Yuka ran to see what was happening, Mayu held her puppy in her arms.

Mayu: What's going on here?

?: I don't want to hurt anyone, right, I need them urgently, especially you, kouta.

The woman revealed herself, she had an average statue, bright dark colored eyes, tight and elegant clothes along with a face that showed coldness.

Kouta: but what.

Nana: how did you do that, you're not a diclonius but you're not a normal human either!

?: My name is Mitsuki Kaname, and I urgently need help.

All: ...

Kouta finally let Mitsuki into her house, giving him some tea so he could relax a little and finally tell her that she was passing.

Mitsuki: Thank you (Takes a sip of tea).

Kouta: Can you tell us what's happening?

Yuka: And how did you open the door just like that?!

Mitsuki: To begin with, Kouta, I've been looking for you for many years...

All that?!

Mitsuki: What I say is true, so many things have happened that still torment me, I felt that there was something in you kouta that, I decided to observe not only you but the others, hidden in the shadows until I knew when was the time to see you.

Kouta: that's...

Nana: Come to think of it, I felt something close to many of us, that something wasn't Lucy or another diclonius, or even a human being.

Yuka, not having an answer about the door, stands in front of Mitsuki to complain to him.

Yuka: None of that explains why you could almost break down the door!

Mitsuki: I'm sorry, I'm also a diclonius like all of you, only without the horns. In addition, in these years that I was looking for them, I also developed other skills such as manipulating and controlling electricity.

Mayu: What?! Nana the diclonius can do that?

Nana: (Confused) No, as far as I know, we only have vectors! Mitsuki, what are you?

Mitsuki: There will come a time when I can give information but, this is not it.

Yuka: then why do you want our help?

Mitsuki: Kakuzawa and... Three musical boxes...

Yuka: Who?

Kouta: Kakuzawa is looking for the music boxes...?

Mayu: Who and what are they talking about?

Nana: Kakuzawa is the director of the laboratory where Lucy and I were locked up, where dad used to be, before Mariko...

Nana: Wait! You're not saying that...

Mitsuki: Yes, the Diclonius research center is still active and it doesn't have good intentions.

Nana: That's ridiculous! He wanted to destroy us.

Mitsuki: It's not...

Kouta: but...

Mayu: If what you say is true, how will we stop it.

Kouta: And what does that have to do with music boxes?! Wait...

Kouta went to the room in her house.

Nana: Mitsuki?

Mayu: What's going on here?

Mitsuki: Wait.

After a few seconds Kouta returned with the music box.

Kouta: Are you talking about this one?

Kouta: Are you talking about this one?

Mitsuki: Yes!

Nana: Why is that box so important?!

Mitsuki: That will be known later, but I will just say that it is not a common music box, it has something inside that Kakuzawa wants to release.

Yuka: Do I still not understand?

Mitsuki: Don't worry, it's normal that they don't understand it.

Nana: Wait, how do we know we can trust you?

Mitsuki: We won't be able to do it in this universe, we have to go to another place, only there will they find the artifacts they need so they can return to this universe and find Saint and Moka's boxes, you will have to take your music box... .

Kouta: Wow wow wow, this is going very fast.

Mitsuki: I'm sorry... We just have to go.

Kouta: Do we all have to go or alone...

Mitsuki: I only need you, Kouta and Yuka.

Nana: Wait, no, I'm not going to leave them alone with, her!

Mayu: I don't mind taking care of the house.

Mitsuki: Well, it's decided, Mayu will stay while you

three will accompany me.

Nana: I'll just go so you don't do anything with them, understand?

Mitsuki just nodded, leading Kouta, Yuka and Nana to where she told them...

Mitsuki's flashback.

Mitsuki: Are you sure she can trust me?

?: More than sure, you and "the others" will be able to avoid the summoning of the Lilium brothers and in the process change the sad history of this world, the ancient humans locked those beings in the three music boxes after purging the ancient diclonius, it was only a matter of time before they fell into someone's hands, or at least that of lilium.

Mitsuki: But...

?: Listen, I know you're scared, so am I... But...

End of Mitsuki's flashback.

Preview of the next episode.

Mitsuki: I had to endure a lot of their retaliation, but it could be worth it, a chance to start over, everyone deserves a second chance, right? In the next episode of "Yo-kai lied" Reunion?
