Here for the last installment of Herald of Destruction.

"Speech"

I don't own anything from Highschool DXD

Underworld: Satans' Palace; Lilith

"Issei. Take this." Ajuka Beelzebub said as he handed him a vial with a strange black liquid in it. Issei is in the Satans' Palace to receive something from Ajuka to use in Issei's fight with Lucien.

"What is this, Beelzebub-sama?" Issei asked the Satan.

"I created something that will temporarily take away his powers." Ajuka said simply.

"How does this work?"

"Lucien simply needs to have skin contact with this. Once he does, he will feel like his skin is burning and his powers will gone."

"Thank you, Beelzebub-sama." Rias said as the entire peerage bowed to Ajuka and then teleported to downtown Lilith. Issei's phone started to ring and he picked it up, looking around to see if he could see anyone from Lucien's peerage observing him.

"Glad you could make it." Lucien said as he chuckled.

"Go west for ten blocks and then wait for further instructions." Lucien said before he hung up.

Issei and the rest of the peerage listened to Lucien's instructions and did exactly as he said. They walked ten blocks west before stopping at the corner of that street, waiting for Lucien's next call. Lucien's call came five minutes after they arrived at the corner.

"Good dragon, now go twenty miles north. That will take you out of town." Lucien said in a condescending voice.

Issei then walked opened up his wings and took flight as did the rest of the peerage. Rias thought about where Lucien could be as this area is heavily industrial except for one place. The phone rang once again when Issei landed after flying twenty miles in 15 minutes.

"Isn't it fun playing Lucien says?" Lucien said with an amused voice as Issei remained quiet.

"No response? That's fine then. Go west for five minutes. You will know the building when you see it. Lucien out." Lucien said as he hung up. Issei and the rest of them walked west for five as a massive building came into view. The building was unfinished and has well over 30 floors.

"That is…." Kiba started before Rias finished.

"That is the Hall of the Fallen Pillars." Rias finished. This building is a monument to those who died in the Great War as it has a floor for each pillar that was destroyed.

"Sure is dark." Issei said as they came upon the unfinished entrance.

"Of course it is. This building project has been abandoned for years as the project ran out of funds to complete it." Rias said as they looked around in the dark to see a familiar sight.

"Otou-san!" Issei said as he ran to his dad who was in a corner. His dad is currently bound and gagged, and shows signs of torture on his body. His face was bloodied and he has numerous cuts on his arms and legs.

"Issei? Is that you?" His father said weakly as he Issei untied him.

"Yes, Otou-san." Issei said as he helped him to his feet.

"What should we do Buchou?" Issei asked Rias.

"He needs medical attention. Koneko, you and Asia go with him to Sitri hospital." Rias said to she created a magical circle for them to transport in.

"Understood." Koneko said as she lifted up Issei's dad before walking into the circle with Asia.

"Ohh hello!" A voice said.

"Lucien!" The remaining ones said as they noticed a walkie talkie lying on the ground.

"Where are you?" Issei screamed into the walkie talkie.

"Don't worry. You will find me soon enough. I'll be waiting for you at the third floor." Lucien said from the other walkie talkie.

"Let's go." Issei said seriously as they looked for the stairs. They walked up the stairs to the second floor and then the third floor where they saw Lucien smiling in the middle of the dark room.

"Yahoo! Hello, how have you been shitty dragon?" Lucien said with a smirk.

"Cut the crap! Where is Okaa-san!" Issei screamed out.

"On the 17th floor. You can only get there through me." Lucien said as he launched a gravity beam that knocked Issei to the ground.

"You can do it Issei-kun!" Rias screamed as Issei got back to his feet to see Lucien standing over him.

"Yes you can!" Lucien taunted as he grabbed Issei by the neck with his right hand and put him at eye level with him.

"Dammit." Issei said quietly as he struggled in Lucien's grasp.

"What?" Lucien taunted him as he put his other hand behind his left ear.

"Got you!" Issei said as he threw the vial at Lucien's face, causing it to break on impact and getting the liquid on Lucien's face. This caused Lucien to release his grip on Issei and he stumbled back screaming at the pain he is enduring.

"What is this?!" Lucien screamed as Issei caught his breath.

"This is something Ajuka-sama made to take away your powers." Rias said with a smirk on her face.

"You can't stop my powers!" Lucien bellowed as he put his hand out to distort the gravity around Issei. To his shock and surprise, nothing happened. He then tried a fire and water spell, but that also failed.

"You are defenseless now." Issei said as he got back to his feet.

"No I'm not!" Lucien screamed as his four remaining peerage members jumped down from the ceiling.

"Kill them!" Lucien said as he ran towards the stairs as his peerage engaged Rias's peerage. Azula engaged Akeno, Rossweisse, and Rias all at once. Cammy fought Kiba and Xenovia, while the two pawns engaged Gasper. Issei meanwhile ran after Lucien.

"Die!" Lucien said as he threw a light spear at Issei as he came up the stairs to the 5th floor.

"Argh!" Issei said as he looked down at his left leg. The spear hit it, but Issei kept pressing forward and trying to get Lucien. Lucien then ran up the next set of stairs with Issei closely behind, firing off Dragon Shots at the retreating Vassago heir.

Meanwhile with Rias and the others, the situation is turning critical. Azula was overwhelming them with her brilliant fire techniques and magical abilities and she managed to knock Rossweisse unconscious with a fist strike to the face. Cammy was holding her own against Xenovia and Kiba and she managed to strike Kiba even with his amazing speed. Jill managed to knocked out Gasper and Chun-Li was about to deliver a killing blow before she was attacked from another source.

"Sona!" Rias said to her fellow Devil. Sona brought her entire peerage with her and it was Sona who fired off a stream of high pressure water at Chun-Li which stopped her from killing Gasper.

"Payback!" Tsubaki Shinra said as she materialized her mirror in front of Azula as she was about to use a fire strike against Akeno. The mirror shattered and reflected all the damage back to Azula, killing her. With reinforcements from Sona's peerage, the three remaining peerage members from Lucien were slowly driven back and killed by the combined peerage.

"Where's Issei?" Saji asked after they finished off Cammy.

"He is chasing Lucien inside the building. Let's help him now." Rias said as the combined peerage raced up the stairs to find Issei. They rushed all the way to the last floor before finding the entrance to the roof, and they pushed it open to see Issei, Lucien and Issei's mother.

"Get back. Get the fuck back!" Lucien said as he held Issei's mother in front of him to be a human shield. He also has a light spear towards her throat and is threatening to kill her.

"Lucien! This has gone far enough." Sona said to her as she looked at the desperate Vassago heir.

"Shut up bitch." Lucien said as he dragged himself and Issei's mom closer to the edge.

"Put your hands down or the bitch gets it." Lucien said as he put the light spear closer to her throat. Mrs. Hyoudou was choking back tears and saying that she doesn't want to die.

"Do it." Rias said as she lowered her hands. The rest of her peerage did the same after looking at their King. Sona's peerage followed in this example. Issei was the last one to aim his gauntlet down and Lucien smiled at this.

"Die!" Lucien said as he threw Issei's mom aside before chucking the light spear at Issei. Issei managed to dodge it and they now have a clear shot at Lucien.

"Now!" Rias and Sona screamed in unison as they launcher their attacks at him. Rias launched her Power of Destruction while Sona fired a stream of water at him. Issei rolled out of the way of the spear and fired a Dragon Short at him.

"AHHH!" Lucien said as all three of those attacks managed to hit him. The force of those attacks knocked him off the building and he fell thirty stories to hit the cold hard ground below and met his death.

"It's all over now." Sona said as she looked over the edge to see Lucien's lifeless body on the ground.

"Yes it is." Rias said as she approached the crying Mrs. Hyoudou to hug her. She then looked at the purple Underworld sky, knowing that this finally over.
