On Earth, precisely in the Nobi house. It was almost dinner time and in Nobita's room, Doraemon was working on something while Selene and the owner of the room watched with curiosity what he was doing, they had no idea what was going on because the robot was preventing them from seeing him work, until they heard a "That's it!" from the blue cat.

The result? A curious bracelet with a purple shiny line with the drawing of a small bat under it, Selene really liked bats so the unusual object seemed adorable to her "This is a... What would I call this thing?" Doraemon thinks about it until he starts "There! A vampire protective bracelet! When Selene puts it on, it will activate a special protective energy to prevent sunlight from harming her, it will also make her body able to produce shadows, and also make her body able to be reflected, thus preventing other humans from knowing that she is a vampire while protecting her from the sun. Although that won't help her with things like vervain or garlic and it won't block her vampire powers. So Selene, be careful not to overdo it."

"I understand the garlic but. Why the vervains?" Nobita asks confused.

"It's a weakness we've had for generations, they're like poison to us, if we come into contact with that plant it burns us like acid, and if we ingest it for some reason, it will weaken us and block our healing properties for a while, which makes a vampire an easy target if they can't be cured, if another species takes the vervain in an infusion and a vampire bites it, it will have the weakening effect as if this ate vervain directly" Selene says.

"Let's try it, right now we're already entering the night so, we'll use the dawn set to test the power of the bracelet" Doraemon gives the bracelet to Selene, who starts putting it on while Doraemon takes the set out of his pocket.

Nobita smiles "I didn't know there was a specific gadget to protect vampires"

"There isn't one per se, not one I can get, so I used the Machine to create gadgets to create the bracelet blueprint and build it. I just hope it works"

As soon as the vampire puts on the bracelet properly, it emits a purple glow that envelops her body and disappears in a second. Nobita closes the curtains in the room and turns off the light to eliminate as much artificial light as possible for a better result. He also removes the night light that protected her since it wasn't going to be necessary if it was going to work.

Darkness had taken over the room, especially since it was already nighttime, so Doraemon takes control of the artificial sun "Are you ready? This small sun, even if it is artificial, emits real sunlight. Don't worry, if it doesn't work and you feel pain, let me know and I'll turn it off quickly"

Selene exhales deeply and with a serious look nods "Do it Doraemon, we don't have daylight or sunlight on our planet, but I have learned about the environment of your planet thanks to my aunt's instructions and the books of our ancestors about their old planet, which I know could kill me, and I have tried to stick a finger out near the window when it was daytime and I almost lost it. But I trust you, I'm ready" Nobita was worried because he didn't want his friend to get hurt, so he approaches her to be by her side smiling at her and in case it doesn't work, he can protect her with his body by standing in front of her so she doesn't get sunlight.

The robot cat turns on the small sun and it immediately rises, radiating sunlight and illuminating the room as if the light in the room was on. Selene had closed her eyes in fear, clenching her fists as she trembled. Seconds later she realizes that nothing had happened to her. Nobita is surprised to see the result; the gadget had worked.

Hearing her friend's light laugh of happiness makes the platinum girl slowly open her eyes to look at herself, she was fine, she looks at the little sun blocking her gaze because of the light towards her eyes, although that was normal even humans were bothered by that, but she was surprised, she wasn't burning, she wasn't turning into dust, she didn't even feel pain or anything, she also notices that her body was producing a shadow, which excites her. "The light isn't hurting me, and... I have shadows, the only shadows I've seen are from the animal species of my planet and yours"

"And you haven't seen the best part" Nobita smiles at the vampire, something was behind her back, it was the small mirror on her desk, which he gives to her, marveling as she holds it...

She could see herself, she could see how she looked, her clothes, her gaze, her hair, everything about her was now reflected in the small mirror, the blush on her cheeks from that sensation was noticeable on her pale skin, Nobita also peeks out. "It's the first time in my life that I see myself in a crystal, we have crystals but we don't reflect ourselves in them, we need the opinion of others to know how we look"

"Now you can see how pretty you are, Selene" Both Doraemon and the girl are surprised by the clumsy boy's comment, until he himself realizes what he just said and getting nervous and with a red face he moves his hands quickly "I-I-I-I mean, now you can see your reflection there!" The boy with glasses laughs sadly while putting his hand on his head, a reaction that for the vampiress was pleasant and for the robot cat it was another sign for another smiling look.

The platinum girl can't help the excitement of being able to experience a different life, even if it's for a while "I'm so excited, thanks Nobita, thanks to both of you!" The vampiress makes her bat wings appear while she jumps for that emotion that invades her body and with those same wings she wraps her human friend in hug mode at the same time that she hugs him with her arms.

It was a double vampire hug that made Nobita blush again, in fact, he had already lost count of how many times she had made his face that tomato color, only limiting himself to laughing embarrassedly and with a "You're welcome" in hesitation.

Nobita's mother called everyone to dinner, Nobisuke had also arrived, who having a slight background on the guest thanks to his wife, or well, the explanation of the (power of persuasion) of the platinum girl, welcomed her, so, placing one more chair at the kitchen table, everyone had dinner quietly.

The vampiress was slowly learning the customs of the place that would be her temporary home, now her horizons had expanded thanks to the gadget she had to use all the time if she wanted to continue experiencing more human sensations. Even at bath time when she had to use it.

After that, it was Nobita and Doraemon's turn to bathe. The boy decided to stay a little longer in the bathtub to reflect on what was happening. He was without his glasses through which his eyes with charcoal pupils could be seen. He wondered what his life would be like with Selene in it. He was able to fulfill his wish of finding the girl he had dreamed of 3 times. Although in reality it was an almost different way than they met in the real world, he felt good about having helped her with her problem.

Although he still didn't understand why he was the only one she could talk to mentally and that feeling of an old friendship that was very recent, but that didn't bother him because, after all, it was a nice experience to help her avoid a fate that she felt chained to and that she didn't like.

He really wanted to tell his friends the next day ("Hey, she's a vampire, apologize to me!") But he felt a bit rushed about the idea of introducing her as she is to others. The pair of evil vampires who want to hurt her caused damage in the city, he feared repercussions for her even if he told his closest friends. Anyway, so many things the boy had to think about, but he came up with a curious idea that made him smile.

When he finished his bath and got dressed in his pajamas, Nobita goes upstairs saying goodnight to his parents, he enters his room and sees that the Anywhere Door was in the middle of his room while Doraemon was waiting for something with his arms crossed. "Why is the Anywhere Door outside your pocket? Where is Selene?"

"Oh, it's because she has to feed. I left it for her so she could go to a place where she can feed on blood, controlling herself of course, which is what she did the first time after she bit you. According to her, since she's a first-class vampire, she can resist longer without taking blood. Of course, that compared to a month of travel where her side dishes ran out quickly are very different situations. Also, she will avoid contact with the Scarlet Moon people if she goes to (have dinner) somewhere far away" Doraemon says while Nobita takes out his futon again that he put away when he went down to dinner.

"But she ate dinner with us" Nobita says somewhat confused

"Yeah but remember that vampires need blood to live, the food we eat doesn't satisfy their appetite for blood. She told me that normal food tasted sour to her, it's possible that her species has different taste buds than ours, although I noticed that she really liked the cherry tomatoes for dinner. Maybe red foods taste the same to both vampires and humans and it would make sense, foods like tomatoes, strawberries, raspberries, red peppers, watermelons and other foods of that kind of color have nutritional value regarding blood and skin protection, and it's possible that's why she liked the tomatoes for dinner. Or maybe it's just because they're red, I don't know, that's my theory."

Nobita makes a disgusted face "I don't like peppers of any color" the boy goes to his desk and takes out a blank notebook and writes something on the cover.

"(Notes on vampires with a friend?) Are you planning to make a research notebook on Amarant's vampires?" Doraemon was curious about what his friend was doing as he approached to read the name of the notebook.

The boy nods with a smile as he opens the notebook and begins to draw himself and Selene, while the vampire returns through the Anywhere Door with her thirst quenched and listens to what her friend says "I'm going to write and draw here what I've learned from Selene, now I realize that I knew very little about vampires and maybe I can learn from her, besides..."

The boy's smile turned sad and she had noticed it "I know she has a home to which she must return, and I think she could take advantage and make a souvenir for her to take with her when she is free as she wants. I understand that feeling of fear of thinking that she could ruin something, I live as a person who may not be able to make an effort to improve himself and that has made everyone think that I won't be able to do something good or stand out, I don't want to admit it, but I earned that"

"She has probably tried hard unlike me and must have felt all that pressure of having to be the Vampire Queen. I know we've only known each other for 2 days but I'd like to help her be happy"

The smile with which the human boy says all that makes the vampiress sketch a warm and grateful smile while listening to her friend's sweet words "Well, I hope it doesn't end up like those projects you dare to do and leave halfway. Although it would be good if you put in some effort at school, maybe that would also help Selene cool her head and understand that she can become a good queen if she lets go of that fear, you would help her more by inspiring her, both like to run away from their responsibilities and although I said I would help, I'm worried about the fact that she leaves her people even though she already has a replacement"

Nobita was focused on drawing himself on the first page next to Selene but he makes a face of displeasure "I already told you that it's not right to force her into something she doesn't want, but I think I'll put in some effort, anyway now we're going to live together for a while, I don't want her to get a bad impression of me"

Selene smiles, she was already behind Nobita and whispers in his ear "What a nice drawing." If something could be heard in that room it was the scream of the pair, not even Doraemon noticed their presence "Vampires are stealthy, remember that well when you write it down in the notebook"

"S-Selene! You're back!" Nobita quickly closes the notebook a little nervous. The vampiress nods and with a movement even faster than him takes the notebook and checks it "W-wait, I-I don't draw that well and...!"

The girl didn't wait to open the notebook just when he told her that, Nobita just covers his face with his hand out of embarrassment, Doraemon looks at the drawing of the pair: A drawing worthy of a 3-year-old child in the hands of an 11-year-old boy. The mechanical cat couldn't help but laugh, the boy gets upset pulling his whiskers a little for that reaction.

Although Selene smiled as she looked at the drawing, yes, it may not have been close to being a Picasso but she could feel what Nobita was conveying with it, a friendly display of affection. "I like the fact that you want to give me a souvenir when I return to Amarant. I still have no idea but... I feel like we've been friends for a long time and being able to communicate with our minds is curiously fascinating."

"Maybe it's what they call in our land (Vampiric Link) something that only happens between vampires but it's very rare for it to happen with another species, almost impossible. Maybe we have a connection that is reflected even in dreams, inside the capsule I dreamed that I was inside an Amarant crystal and someone freed me, the funny thing is that that person smiled at me while extending his hand towards me, that's why when we saw each other for the first time, I was stunned because the one in the dream was you, Nobita"

"Really?" Nobita is just as perplexed as she is and points to himself "In fact, I found you because I dreamed of you inside a violet crystal and when I freed you, you told me to look for you and I guided myself in the dream to find out where you were." They both stand stunned, they had dreamed the same thing but from a different angle, it's possible that there was a link after all, although they didn't know why, it didn't bother them because they both liked each other.

"We can speak the language of others when we absorb their blood, that's why, when I bit you I could hear your regret for what I did, I felt so guilty. I'm not going to feed on you again, or your neck, or your arms or legs, we can absorb blood from other parts of the body, although the neck is much better. But I'm not going to do that again." The vampiress lets out a guilty and sad sigh, although Nobita only laughs low and nervously.

"I already told you not to feel bad about it, you were having a bad time, but if there is another moment like that and there is no other option, then I give you permission. Just be careful when you sink your fangs, my neck still hurts a little" The boy rubs his neck while saying that

"Buddy, be careful with what you let happen, remember that you almost got anemia" Doraemon had the alerts activated, he was helping a vampire, but he wasn't going to let her and his friend get careless either.

Nobita laughs again with shyness but looks at Selene and she looks at him "But seriously, we are friends now and that is why I want you to take a good memory of me and my world when you leave. Although it will make me sad when you return to your world, I want you to keep some of our friendship. I have an idea."

At that moment, the boy raises his arm and pinky finger in front of his supernatural friend, she didn't understand that gesture which startles the boy "Don't you know the pinky promise? We make a promise between the two of us and this one will always be kept, it's a very powerful promise, you know? Let's make one ourselves, that we'll always be friends, no matter what happens. Okay?"

"Powerful promise?" The vampire is stunned as with everything new she's been learning, but she smiles because she thinks it's something cute. So doing with her friend's guidance, she intertwines her pinky finger with his making the promise "It's a promise then"

Thus, both the human boy and the vampire princess make that promise while laughing quietly and smiling at each other fondly, all while the moon was high in the night sky ending another night in the life of the little vampire.
