The 10 Years Quest has been done perfectly and both Ben & Mira get their magic strengthened. They have returned to Magnolia after confirming the job completion with the Country of Deserto. Now they are resting in their home after having a far & long journey.
Ben is sitting on the couch while thinking deeply, so Mira asks, "What are you thinking about so seriously?"
"It's about my immunity to Curse. I didn't think too deeply about it before, but that old Etherious is right, this is strange," says Ben.
"Isn't that because you are a Devil Slayer? As a Devil Slayer, you should be immune to Demons' forms of attacks, including Curse, right?" asks Mira.
"That is possible, but it still doesn't feel right. My Sun Devil Slayer is Magic, not Curse. They originated from different sources, so I shouldn't be immune to Curse," says Ben.
"Hmm, you said you've learned Curse in the past, right? Maybe you get something from that," says Mira.
"I've learned it, but I still can't use it well to this day. So I doubt I get something from it," says Ben.
"Then, maybe your Sun Devil Slayer Magic is special," says Mira.
"Special, huh? Maybe that's true. The Sun Demon who used this magic could fight a Sun Dragon almost equally even though Devil Slayer Magic is supposedly weaker than Dragon Slayer Magic. But Midas the Sun Demon could injure Escanor, a Sun Dragon," says Ben before he widens his eyes in realization.
Ben suddenly stands up and runs to the training ground in his basement while thanking Mira for giving him a clue. Mira just sighs and then smiles because Ben has been troubled by this matter since they finished their job.
In the underground training ground, Ben makes a miniature Red Sun using his Sun Devil Slayer Magic. Then he asks A.I Chip to analyze it thoroughly using every data that they have now. They have a lot of data after getting a lot of knowledge in the last 4 years.
[Scanning Sun Devil Slayer Magic.]
The scan takes longer than Ben thought. A.I Chip only finishes after 5 minutes because it checks everything thoroughly using every data it has just like what Ben asked.
[Finding irregularity in host's Sun Devil Slayer Magic. Signs of Curse ability can be found in the host's magic.]
Ben widens his eyes, "What the!? Curse?"
[Yes, the power of Curse has been integrated into your Sun Devil Slayer Magic. The signs also have been found in the first data of Sun Devil Slayer Magic. However, the signs were very faint that they were undetected. The data in my memory storage was lacking at that time.]
"So you couldn't detect it because you didn't have enough data, but I've got this Curse power since I got my Sun Devil Slayer Magic?" asks Ben.
[Yes, although it was not developed yet at that time. After giving a deep check, I found an increase in the power of the Curse in your Sun Devil Slayer Magic. It was when you killed a lot of Etherious Demons in your 10 Years Quest. The cause was the strengthening of your Sun Devil Slayer Magic after you absorb the power of the Etherious Demons that you have slain. It was not only their magic power that you absorbed but also their Curse power.]
"So it's like that. Then, can I learn to use Curse now?" asks Ben curiously.
[There is no need for you to deliberately learn how to use it. By using your Sun Devil Slayer Magic, you have used your Curse power too. It has merged with your Sun Devil Slayer Magic completely.]
"Damn, that's convenient. Was it because Midas the Sun Demon has combined Curse to his magic?" asks Ben.
[Yes, it is assumed that he could damage Sun Dragon Escanor using his lower tier Sun Magic because of the Curse power. Sun Dragon Escanor didn't have immunity toward Curse, so he could get injured by Sun Demon Midas's attacks.]
"Hoo, so that means I can use my Sun Devil Slayer Magic to injure Dragons, maybe even Gods because of the unique Curse power. Wait! Ankhseram can use Curse if I'm not wrong, so maybe other Gods can. This might not be that effective on Gods. Well, I have Sun God Slayer Magic, so no problem," ponders Ben.
"It will still be of use to be used on Acnologia though. Still, it seems my Curse power is still weak and I don't know much about it. A.I Chip, create a training course for my Curse power! We will hunt more Etherious Demons in the future. They only use Curse, after all, while normal Demons also use magic. Besides, I don't need to worry about targetting friendly demons because all Etherious Demons are evil," says Ben.
[Understood.]
A.I Chip makes a training course for Ben to improve the Curse power of his Sun Devil Slayer Magic. The training is still lacking though because they don't have enough data about Curse. So Ben needs to gather more information about Curse.
Since that day, Ben is focusing on improving his Curse power. It will surely be useful for when Acnologia appears again. If even Escanor, a Sun Dragon, one of the Ancient Dragon Gods wasn't immune to the Curse of Sun Demon, then Acnologia won't be immune too.
It's not easy to find information about Curse because humans don't use it. But Ben can still get some information even though he needs to use all his connections and even money. It's not a problem for him because his Car company is doing well and money keeps entering his pockets.
He wants to get information about Curse from Demons, but there are no jobs involving Demons here. Ben knows some Demons, the Demons on Galuna Island. But those Demons aren't too knowledgeable with Magic nor Curse. His dead Demon friend, Morgbitt, gave him more information than these Galuna Island Demons.
But even without much information, Ben's progress on his Curse & Sun Devil Slayer Magic is good. He knows all the basics and A.I Chip can use other knowledge to improve the Curse. Besides, as his mastery over his Sun Devil Slayer Magic improves, the Curse within it will also improve now.
Then, 4 months after he finished the 10 Years Quest, Fairy Tail finally gets another Quest involving demons. Ben is excited because he can finally get more information about Curse using the demons in this quest.
He immediately asks Mira to take this quest together because absorbing Demons' souls can strengthen her Take Over Magic. She agrees, but Ben realizes that she looks quite pale, and she looks tired for some reason.
"Are you okay?" asks Ben as he takes Mira to sit on a chair on the Guild's 2nd floor where S-Class or above quests are placed.
"Ye-yeah, I am fine," says Mira with a not-so-fine expression.
Suddenly, Mira feels nausea, and she feels like vomiting, so she runs to the toilet. Ben is panicking because this never happened, so he follows her. Mira vomits a few times while Ben is panicking behind her, he doesn't know what to do.
After she stops, Ben immediately takes her to Porlyusica using his teleportation. The old woman is annoyed by their sudden visit, but she doesn't nag them after seeing Ben's panicked expression and Mira's condition.
Porlyusica checks on Mira inside her house and Ben watch it nervously. He had never seen Mira get sick since 4 years ago because she has gotten so much stronger. But now, she suddenly gets sick, and her condition looks quite bad, which makes him very worried.
Everyone in the guild is rushing to Porlyusica's place now. Erza saw Mira runs to the restroom, followed by the panicked Ben. She went to check on them, but then she saw they teleported after Ben mentioned Porlyusica, so she assumed that Mira is sick, and she told the others, which made them all run to Porlyusica's place.
Sometime later, the big group arrives, and they see Ben standing in front of the treehouse while looking at the sky blankly. They all are staring at each other and hope that nothing bad happens. Lisanna steps forward to ask Ben about her sister.
"Ben nii-chan, where's nee-chan?" asks Lisanna.
Ben blankly answers, "Inside."
"Is she okay?" asks Lisanna again.
Ben nods and answers blankly again, "Yeah, she is fine, she is just pregnant."
Lisanna & the others sigh in relief, "Phew, so she is just pregnant."
Silence suddenly falls there, before they all shout, "..... PREGNANT?!"
