This chapter will be the start of all the big, main fights of the arc. Next chapter will cover both Natsu vs Riser and Lucy vs Isabella, then the one after will be just Lucy and Isabella. Stay tuned for the next chapters and I hope you enjoy! (I'm repetitive, I know.)

The team gets to the front door of the mansion. They're greeted with the first of many riddles. "There are many like me, but only one me, tall and handsome, who am I?" "Something tells me that the answer is Riser. Just a hunch.", Issei said. "Correct!", the voice said and opened the door. "Called it!"

They proceeded to enter the mansion. The building was huge, but they could sense intense magic from upstairs. "That must be them upstairs! Let's go after them!", Natsu yelled. "Riddles are everywhere, be careful!", Akeno said. Natsu charged up the stairs, only to smash into an invisible wall. "Hey! Who put the wall here!", he yelled.

"Another riddle perhaps?", Zeref asked. "I'm burning bright, have strong might, and very good eyesight. Who am I?" the riddle voice said. "Let me guess, Riser.", Issei said jokingly. "Correct!" the voice said. "Oh come on! Really!?"

"I'm sensing a theme here. A sense of 'unoriginality'.", Zeref said. The team advances through the mansion, encountering riddles and more enemies. Meanwhile, in the master bedroom, Riser and Rias hear that they have intruders.

"I expected nothing less of them to show up. They'll be tired before they reach here, then we can destroy them.", Rias said. "Riser likes your thinking. I knew we were a perfect match.", he said as they both giggled. Before they knew it, the bedroom door was kicked down.

"We're here for Rias! Now give her back!", Natsu yelled. "No one talks to Riser like that, prepare to die!", his pawn yelled. "Stay out of my WAY!", Issei yelled, yet again, backhanding her. "Showing no remorse, Issei, you savage.", Akeno said. "I'm all fired up! Bring it on!", Natsu yelled. "If you want your girls back, Sabertooth, then tell your friends to…", Riser stopped to see Happy, Gajeel and Pantherlily enter the room with Yukino and Minerva. "No need to worry, there with us.", Lily said. "What!? How did you…?", Riser yelled.

"My my, Issei you've gotten stronger. Not as strong as me, however.", Rias said walking in from the balcony. 'Her eyes are bright green, could that be what Akeno said?', Issei thought to himself. "Rias, your under mind control! Snap out of it!", he yelled. Everyone paused and looked at Rias, to only see her laugh. "HAHAHAHA! Don't make me laugh! You think that I'm mind controlled? I had a change of heart, Riser means more to me now.", she said.

"Riser's magic over her doesn't work like the love charm, you have to beat them back to their senses. Good luck with that.", his queen said. "I'm well aware of that. That's why I will defeat her and bring her back. To protect her, I need to be stronger than her!", Issei yelled. "Welsh Dragon, Balance Breaker!" Ddraig yelled. Issei obtained his scale mail armor from training.

"What's this? You were just a weak pervert, now you went in Balance Breaker. That's still not enough!", Rias yelled blasting Issei will black colored magic beams. "Welsh Dragon's Crimson Slicer!", he yelled throwing blades at the beams, destroying them.

"Now you're dead, Hyoudou!", she yelled. Issei and Rias flew into the sky while the others are on the ground fighting. "Riser, you combusted our guild hall and kidnapped the ladies of Sabertooth, now you will feel the wrath of Fairy Tail and Sabertooth!", Natsu yelled. "Riser's not alone, you see. Kill them.", he ordered. "Natsu, we'll handle the pieces, you, Gray and the twin dragons go after Riser!", Larcade said. "You're catching on quick, I like that. "Don't let me down you guys!", he replied. "They nodded and proceeded to fight the evil pieces. Natsu and the others are chasing Riser to the courtyard. When the arrive, they see Riser and his older brother and younger sister, Dianne.

"Oh look, we have company! How fun, now I can get my hands dirty.", Dianne said. "This is an odd match up. How bout we kill one of you to make it even.", The brother said. "Or I can help them fight. Two for one seems even, right?", Juvia said appearing from a magic circle. "Juvia, how'd you get here?", Gray asked. "Sirzech gave me flier with a magic circle on it. I used it to get here.", she replied.

"What? The nerve! Time to die then, scum!", Riser yelled. Sting and Rogue charged at the brother, Gray and Juvia charged at Dianne, and Natsu charged at Riser. Their fight started to destroy the courtyard and burst into flames.

Sirzech's office:

"Why did you bring me here? Am I important to you?", Acnologia said. "Yes, Zeref told me your story. I know you lost your family to the dragons at the Dragon King Festival. Also that the humans who treated you like trash because of the poverty you were in. That's why you have dragons and humans.", Sirzech said.

"I wasn't this crazy dragon of destructive evil people made me out to be. I learned take over magic so I can take the soul of a dragon, and take revenge on the evil dragons that killed my family and to bring fear into the humans. But this power took control over me, I wanted a dragonslayer to stop me from having this power.", Acnologia replied.

"Well I have something I want to show you, follow me."

Back to the mansion, Natsu and the others are still at it. Riser's brother is tuckered out and almost about to pass out, same with Dianne. "Let's finish the, Sting!", Rogue yelled. "Right! White Shadow Dragon's Flash Fang!", they yelled using their unison raid attack. The brother screamed in agony and laid on the ground passed out.

"Brother! Why you…!", Dianne yelled but was stopped by Gray freezing her feet. "Why can't I melt the ice? What magic is this?", she questioned. "My ice was made to slay demons, it can that the heat.", Gray replied. "What?! Please, I surrender! Let me go!", she pleaded.

"Sorry, but we show no mercy to enemies of Fairy Tail. Ready, Juvia?", Gray said. "Yes, let's end this.", She replied. "Let's work things out, please come on!" she pleaded again. "Not a chance! Ice Water Devil's Liquid Avalanche!", they yelled using their newly created unison raid. Dianne screamed before lying frozen on the ground.

"Way to go, guys!", Natsu yelled. "What have you done?!", Riser yelled. "No matter, I'll use their power for my own." Riser started to absorb the unconscious bodies of his siblings. His body began to grow 3x its size and got very burly.

"Now you will feel the wrath of a true devil! I am the Ulti-Phoenix!", he yelled. "What the hell?! This guy's crazy!", Gray yelled. Yeah, Natsu might need our help.", Rogue said. "I got this. Don't you worry.", he replied.

"Natsu, are sure about this, we don't know if you can control that form!", Gray said. "I wasn't mindless fight you in it, was I? I can take him.", he replied. "What are you getting at, boy!", Riser yelled.

"You call yourself a true devil, I'm a demon, the strongest demon from the book of Zeref!", Natsu yelled. Natsu began to transform, with black aura on his right side and a dragon wing with flames and lighting on his left. "What is this power?", Riser questioned "I'm glad you asked.

"I am Lightning Flame E.N.D!"
