Finally back at Magnolia, Natsu does his best to process what he'd learnt while on the train, yes he took a train and it went well for the first time in his life, after collecting his reward, out of curiosity he'd asked what was in the two boxes that contained, in which the old man was cautious about but he ended up giving Natsu the boxes that contained two of Sukuna's other fingers, why give him you may ask well……..do you seriously want to watch over fingers your whole life and attracting curses to your village? No? Good thing you understand. 

After digesting the two other fingers and heading to another town to catch a train, Sukuna took the time to actually explain what Curses were and how they work, as well as curse energy, weapons and other things related to that topic as well as Jujutsu sorcerers; upon learning all this info, Natsu demanded he be taught so he can fight such beasts, but Sukuna wanted no hand in it and in response to that, Natsu refused to give Sukuna the ability take over, so they came to an agreement, when Sukuna mention Abraxas he would give him control for 2 minutes and he forgot about the deal, but Natsu disagreed so they changed the second one to Sukuna not killing anyone, though that didn't mean he couldn't hurt them. 

"For my host, you live in an awfully loud town" Sukuna said. 

"Shut up before someone sees you" Natsu growled. 

"At least you could've taken a shirt from them" Sukuna said. 

"Don't remind me, I feel like Gray" Natsu said. 

"Why would you co-OW!" Sukuna said before Natsu slaps his hand over the mouth, but the pained cry was muffled and this happened when Natsu saw Happy and Lucy walking his way. 

"Hey Natsu, you done being on your period?" Lucy said jokingly. 

"Yeah, I'm sorry about yesterday Happy, I got you a bag of fish" Natsu said, holding up a bag of fish, as the Exceed cheers and hugs the bag. 

"All is forgiven" Happy said.  

"Thanks lil buddy, so how's Gray?" Natsu asked, as they walked to the guild. 

"He's doing fine, but the others are angry with you for what you did" Lucy said. 

"Of course they are, but when I said to drop it no one listens" Natsu said. 

"What's interesting is the fact you're calling Gray by his name and not something insulting" Lucy said. 

"Just changing is all" Natsu said, to say that what he'd done was an eye opener would be an understatement, he's now seeing the world for what it is and is still trying to come to terms with what happened. 

"Sure, you've definitely matured" Lucy said. 

"I don't need any of this" Natsu said. 

"I'm just kidding, also where are shirt" Lucy asked. 

"Got torn" Natsu said, as they finally arrive and he just simply opens the door, catching everyone's attention which has people giving him different kinds of looks. 

"Welcome back Natsu, how was your mission?" Mira said, as Natsu walked towards her.

"It went well, a little weird but nothing I couldn't handle" Natsu said. 

"That's nice to hear, also Master would like to meet you in his office and here" Mira said, pulling out the same shirt Natsu wears, as Natsu groans and takes it to put on before heading to Makarov's office, knocking and getting a response to enter. 

"Afternoon Gramps" Natsu greeted. 

"Same to you Natsu, now please can you explain why Gray was knocked out cold yesterday?" Makarov said before asking. 

"I was in a bad mood, and everyone kept on asking, I know they're trying to help but I don't want anyone to know what I did" Natsu said. 

"And what did you do to put yourself in a bad mood?" Makarov asked. 

"It's hard to talk about it, I still have nightmares about it" Natsu said. 

"What is it Natsu? I am here to help" Makarov said, as Natsu took a deep breath and explained what happened with the last solo dark guild quest, it shocked and angered him that Natsu had killed a bunch of kids, but when he learnt that's what they wanted his anger was now on the jailed dark guild master, even learning that even the parents couldn't recognize their children was another shocking fact. 

"I see, thank you for the info, Natsu, there are going to be times where you can't do much and I understand, but please do not take it out on others, I think when you apologise you should take some time off" Makarov said. 

"Thanks for understanding Gramps" Natsu said, smiling a little. 

"It's no problem, this meeting won't be leaked I assure you" Makarov said. 

"Thank you again, anyways see ya around old man" Natsu said leaving. 

"Same to you brat" Makarov said. 

Later that day…….

As the day went by, everything was seemingly back to normal though Natsu wasn't there, he was back at home training to harness and control cursed energy which was proving to be somewhat of a challenge but he was advancing at an alarming rate which was good for Sukuna. 

"Kid you're a natural, soon enough you might be able to fight me at full power" Sukuna said. 

"Really?" Natsu asked. 

"Not in a million years, dumbass, you'd die within the first 5 seconds of my presence" Sukuna laughed, as Natsu scoffed at the demon but he then picked up a scent coming his way. 

"Someone's coming……….Oh Mavis it's Erza" Natsu said before trembling in fear. 

"What's so scary about this person?" Sukuna asked intrigued. 

"She's one of the strongest wizards in Fairy Tail, Erza Scarlet aka Titania of Fairy Tail, I really pissed her off yesterday" Natsu said, but then blushing a little at thought Erza still being cute when she was mad though when that anger is aimed at someone else. 

"Strongest hm? Abraxas!" Sukuna said. 

"Shit" Natsu thought, allowing Sukuna to take over and sending the dragon slayer into the inner world; within minutes Sukuna was prepared with a few cracks of his neck and stretches, though Erza finally arrived and was face to face with him. 

"Natsu, I am glad to see you are back, as for what you said I will not stand for such and I urge you to watch your mouth next time" Erza said in her usual stern voice, but to many that persona was trembling a little. 

"Titania, I believe this battle between both of us should be interesting" Sukuna said, flexing his finger muscles. 

"Natsu? Is something wrong with you?" Erza asked, concerned. 

"This is not your friend, this is the King of Curses, Ryomen Sukuna" Sukuna said, as now Erza took it much more seriously. 

"Why do you look like Natsu? Where is he?" Erza demanded re-equipping a sword. 

"He's here, I just took over his body is all" Sukuna said with a sickening smile. 

"Give him back his body" Erza commanded. 

"Ah ah ah, we made a deal you just have to survive the next 1 and a half minutes" Sukuna said wagging his finger, as Erza charged at him. 

"Then so be it" Erza said, slashing at Sukuna at very high speeds but he was simply dodging every single one, before stopping the speed with his two fingers and breaking it. 

"You are supposed to be strong, how am I supposed to enjoy this?" Sukuna asked with a grin, as Erza growls and requips her Clear Heart Armour. 

"What are you doing woman? Are you trying to have sex here and now?" Sukuna asked laughing, as Erza charged at him using speeds that proved to be somewhat funny to him, but it still didn't satisfy him; just as she delivers the last dual X slash, something grabs her by the pants of the outfit. 

"You're boring" Sukuna sighed before throwing Erza into the air. 

"He's stronger than I thought" Erza thought, as Sukuna appeared in front of her. 

"Stop being boring, satisfy me" Sukuna yelled, kicking Erza into the ground. 

"Ack" Erza coughed, releasing a great amount of blood. 

"Get up and show me the power of the great Titania" Sukuna said excitedly, grabbing Erza by her hair, pulling her up and spinning like a beyblade, taking the sick pleasure of hearing her cries of pain before letting go letting her break through multiple trees. 

"He's far beyond anything I imagined" Erza said, pulling herself up but saw Sukuna homing in, unleashing a dark aura that shook her to her core and in the most unexpected turn of events, she turned around and tried to run away. 

"This isn't normal, he's the living entity of darkness" Erza said to herself. 

"I-I-I-I-I don't want to die, I didn't even get to tell him how I felt" Erza thought, holding back tears that spilled. 

"This is pathe-" Sukuna said, being cut off, as Natsu took over. 

"Erza! Erza! Wait I'm back!!!" Natsu yelled chasing after her, though she was on autopilot before she was stopped when Natsu grabbed her arm. 

"Erza calm down" Natsu said, pulling her to him and making her face him, she was bruised badly around her stomach, scratch marks around her body, her face included and she was covered in dirt.  

"Erza please breathe, breathe in and out" Natsu said as Erza tries but was still filled with fear, though soon she does and immediately passed out from the pain. 

Sukuna you bastard you said you wouldn't hurt her or my friends" Natsu growled. 

"Hahahaha! I said I wouldn't hurt them too bad" Sukuna laughed. 

"I swear, I regret eating you…….pause" Natsu said, picking up Erza bridal style and taking her to his place. 

"Don't worry Erza, you'll be better and I'll explain if it's the last thing I do, so please don't cray again" Natsu thought.
