Hey everyone. Merciless Sun here with the next chapter of How To Stop A Devil Civil War. In the last chapter, Isaac and Isabel trained and planned to have a date with Rias, but instead had some company. In this chapter, they will finally see the Rating Game between Sirzechs and the Phenex family. Enjoy.

-Isaac's Apartment, The Next Morning, 6:30, Isaac's POV-

We all got woken up by Rias' alarm, and we all woke up. Rias said, "Well, today's the day."

"Yeah. What time does it start?"

"It starts at 10. I'd like you all to stay with me today."

I said, "Of course. I'll make sure you're not alone today."

Rias then kissed me, but something didn't feel right. Asia then held Rias' hand and said, "You'll be fine with us all here."

Isabel said, "Isaac and I will protect you no matter what happens. Well, let's take a shower."

I said, "Right."

-Kuoh Academy, 45 Minutes Later, Isaac's POV-

We just got to the clubhouse, and I said, "It's been a while since I've been here." When we went in, I saw Akeno, Kiba and Koneko. I said, "Hi, everyone."

Koneko said, "Hello, stud."

I said, "Hey, Koneko."

Akeno said, "Would you like some tea?"

I said, "Actually, I'm gonna take a nap until the Rating Game begins. Wake me up then."

I then got on the couch there, and went to sleep.

-2 Hours Later, Isaac's POV-

I was woken up by Akeno, and I said, "Wha….Oh, it's time."

I got up, and saw 3 girls: one with short black hair, violet eyes, glasses, and a school uniform; another with long black hair with split bangs, also wearing glasses for her purple and light-brown eyes, and also wearing a school uniform; and one with black hair in twintails, blue eyes, and wearing a Magical Girl costume. Akeno then said, "Isaac, Isabel, Asia, meet Sona Sitri, Tsubaki Shinra, and Miss Serafall Leviathan, one of the 4 Devil Kings. They are here to observe the Rating Game with you."

I got up, and said, "Nice to meet you all. I am Isaac Fennis. And this is Asia Argento, and Isabel."

Sona calmly said, "Nice to meet you all, Rias has told me a lot about you, Isaac."

Serafall then came up to me, and said, "I heard a lot of things about your Rebirth Gear from the ceremony last month."

"Yeah, but that was back when it was weak, I trained with it yesterday, and is so much better now."

She chuckled and said, "Good to hear, can't wait to see what else it can do in the coming days." She then winked at me.

I blushed, and Rias said, "It's nice for you all to come. It's about to start now. Actually, we're missing a guest."

Just then, we heard a child say, "Aunt Rias!" A small boy with red hair and noble clothes came running in, and hopped onto Rias' lap.

Rias said, "Millicas! It's so good to see you. Are you ready to see your father win this match?"

"Yeah, I can't wait to see mother either!"

Rias giggled and said, "Everyone, this is Millicas, my nephew."

I said, "Nice to meet you, Millicas, I'm Isaac. I saved your aunt from being taken away."

"I heard about that. Thank you."

Akeno then said, "Everyone, it is time."

A huge screen then popped up, and we saw 15 men and women lined up in front of Sirzechs, one of them being Grayfia. And about 20 yards away from them are 15 girls lined up in front of a man with medium-length blonde hair.

I said, "Okay, so who is that guy on the Phenex side?"

Rias said, "That is Riser's older brother, Raze."

"I see…."

A couple of girls with swords from the Phenex side rushed ahead, when a man and woman from Sirzechs' side ran out as well and clashed. They kept fighting while more members of each group started clashing.

I asked, "Okay, so how does a Rating Game work?"

Akeno said, "Well, each member of a Devil's group is named after a chess piece, such as me being a Queen, and Koneko here being a Rook."

"Then that makes Sirzechs a King, right?"

"That's right."

We kept watching as a Knight from Sirzechs' side got knocked out. A Magic Circle then appeared, and started to disappear. "So where is that Knight going?"

"Well, anyone who gets knocked out is teleported to an infirmary."

A few more fights were going on for about 10 minutes, and with them, 3 girls from Raze's side got knocked out, and 2 more from Sirzechs' side. I looked over at Rias and saw her grip Millicas tighter, so I walked over to her desk, and said, "Your brother will win, Riser won't be able to get near you again."

A tear streaks down her cheek, and said, "I'm not worried about him getting to me."

I put a hand on her right shoulder, and kept watching the fight. I saw Grayfia walk towards a woman with dark purple hair. Grayfia lets loose with a huge lightning blast, and the woman countered with an even bigger blast of fire! Akeno came to both of us, put her hand on Rias' left shoulder. "Lady Grayfia's magic will outlast anyone. She is known as the Strongest Queen, after all."

Millicas then looked away. Shit, that doesn't exactly instill confidence. Grayfia made the blast bigger, but just then, a spear pierced her chest! Rias and Millicas looked away! Grayfia was about to vanish when the woman hit her with a big blast of fire. Then many of the remaining members of Sirzechs' group were being killed! I said to Akeno, "Get Rias and Millicas out of here!"

They then started heading to the shrine. Isabel said, "Not how any of us expected this to go, huh?"

"You ain't fucking kidding. I just hope Sirzechs can survive this."

We look at Sirzechs blasting Raze with a huge blast of Destruction, and Raze just grins, runs through it, and grabs Sirzechs by the throat! We hear him say, "Riser was right. No Devil shall command the Phenex family!"

He made a sword of fire, but Sirzechs slowly snapped his fingers, and vanished. Koneko said, "Thank goodness. Had he died, the entire Underworld would be in turmoil."

"No shit, but this ain't over."

The screen shut off, and I said, "I can't fucking believe it! I knew this would happen, and now we have to ensure Rias doesn't get taken again!"

I punched through Rias' desk, and fire got around me. Isabel walked towards me, put a hand on my shoulder and said, "Calm down. Why do you think we trained? We'll make sure they do nothing to her."

I took a deep breath, and said, "You're right. I'll text Akeno to take them to the shrine."

I texted Akeno and said, 'The fight just finished up. I'll give you all the details, but take Rias and Millicas to the shrine you talked about. Text me the coordinates, and we'll all be there.'

Asia then said, "What do we do now?"

"I don't…" I then sensed a huge blast of energy! "Get down!"

I then made a huge shield with the Life Fibers as it destroyed the entire clubhouse! It dissipated, and in walked a woman with long brown hair, purple eyes, glasses, and a low-cut dress. She said, "You are quite durable for a Human. Too bad that endurance won't mean shit!"

Serafall said, "I heard you had busted out of the Underworld Prison, Katerea. But I'm not in the mood for this! FIRE BLAST!"

The woman, Katerea, was then blasted out hundreds of miles away. I said, "Who the hell was that?!"

"That is Katerea Leviathan, a bastard child of the Leviathan bloodline, she tried to kill me a few decades ago, and was imprisoned for it, but it seems she is working with the Phenex family. Let us leave before anything else happens."

"Right. Let's get to Rias, she'll need all the help she can get."

I was then texted the location by Akeno, and we all went there.

-Shrine On Top Of A Hill, 20 Minutes Later, Isaac's POV-

We just got to the shrine, and I said, "I'll go inside to make sure we're at the right place."

Asia then held onto my hand, and said, "I'm coming with. I feel safer with you."

I smiled, and said, "Okay."

As we were walking there, Asia said, "I can't believe that happened."

"Me either. Rias has got to be devastated. But Isabel and I will protect you both."

We both then walked in, and saw a set of stairs going down. We saw a big room with 3 couches, Rias hugging Akeno, crying, and Millicas hugging Rias while also crying. "Hey guys, I'm back."

Rias then ran to me, tackled me onto the ground, and said, "I'm so glad you're safe!"

"I missed you too, Rias. We were attacked though, by this woman, Katerea Leviathan. But Serafall saved us."

Rias hugged me, and kept crying, while Akeno said, "Interesting. I don't know why Katarea would side with the Phenex family, but it's good that you're safe, Isaac."

"Yeah."

I hugged Rias tighter and kissed her forehead. I then got up while hugging Rias, and said, "I did not think it would go that way. It looks like Grayfia is dead, but Sirzechs was able to escape, but I don't know where he went."

" I see. I'll head to the Gremory estate and see how he is recovering."

"Please do. Rias and Millicas don't want to hear anymore bad news."

Everyone else then came in, and Sona said, "Glad to see you're safe, Rias."

Rias smiled and replied, "I'm just glad you didn't get hurt from the attack. Isaac, could you please lay with me on the couch? I don't want to be alone."

"Of course." We both went to one of the couches, and fell asleep.

-4 Hours Later, Isaac's POV-

I just woke up, and Rias was laying on top of me, still sleeping. Isabel then came up to us, and said, "Good afternoon, Isaac. Clark called earlier, but I didn't want to wake you."

"Thanks, Isabel." I then shook Rias awake. "Hey, it's time to get up."

She slowly got up, and said, "Oh...Ok."

She then got up, and held onto my hand. I then turned on the holo-screen, and Clark appeared. "Hey guys. How did the Rating Game go?"

I replied, "You really want the answer?"

"Oh shit. What happened?"

"Well, almost everyone in Sirzechs' group was slaughtered, including Grayfia, but Sirzechs was able to escape, and now we're all hiding out in a shrine Akeno took Rias and Millicas to."

"No...No fucking way!"

"Yeah, it was devastating. But now we need a strategy to stop Raze Phenex from getting his way and freeing Riser."

"I see….First get allies."

Rias said, "We do have Sona, Tsubaki and Serafall Leviathan here."

"That's a good start, but I think you can do better. I want you to get your Bishop."

Her eyes widened, and said, "Never thought I would have use of my Bishop."

Isabel said, "I also have a theory. I think the Fallen Angel, Raynere, may have been working with someone other than Riser Phenex. Do you know of any bases she would have had?"

"Well, there was a church Asia was at, but I'll look into it."

I said, "Please do. I'm starting to think Isabel's paranoia is right. But we'll look into getting more allies. We'll let you know what else happens."

Akeno then said, "I was able to speak with the head of the Gremory family, Zeoticus, and Sirzechs is alive, but in a coma. However the family healers are working diligently to help him recover, so he should be fine next week."

"Good. Good luck, guys."

The holo-screen shuts off, and Rias then leans onto my shoulder. I frown, and put my arm on her shoulder. "I got you…."

Akeno said, "Well, I'll help your friends to move your stuff in here. You and Rias stay here."

I quietly said, "Thanks. We need this."

They all leave, and I hug Rias. She cried a little more, and said, "This won't be easy, will it?"

"No, but we're strong. We'll fight whatever obstacle we have, and I'll make sure Riser doesn't take you again."

She keeps crying, but she comes up for a kiss, and I kiss her back. She opens up her blouse and brings out her breasts. I then squeeze them and keep kissing her. We both keep kissing each other, for another hour.

-Cave In The Underworld, General POV-

There are 4 men in noble clothing at a table with a battlefield map. A man with long blonde hair talks to Raze. "You have lost your mind, Raze! We were meant to scare Sirzechs, not almost kill him!"

"Calm down, father. If we are to be the rightful rulers of the Underworld, then we must eliminate all enemies, no matter what they claim to be."

He then walked out of the cave, and towards an unknown manor.

-Underneath The Shrine, 3 Hours Later, Isaac's POV-

Rias and I fell asleep after we had made out, so her breasts were still out. I was poked awake by Akeno. "What….Oh. What time is it?"

Isabel walked down, and said, "It's about 5PM. We moved everything from the apartment, so we're all set with our new base."

I wake up Rias, and she buttoned her blouse back, and said, "Good. Where is Millicas?"

Akeno said, "He's sleeping in the other room."

"Good, what happens next won't be for children."

I say, "But first, dinner. It's been a long and difficult day. So I think I'll cook what Isabel and I had planned for us."

Isabel smiled, and said, "Then it's a good thing I picked up a few more steaks and asparagus."

"Alright, let's get cooking!"

-30 Minutes Later, Isaac's POV-

Isabel and I come out of the makeshift kitchen with 9 plates, each with a medium rare steak, asparagus with garlic butter sauce, and a slice of the strawberry cheesecake. Rias said, "Your cooking is just incredible!"

I grinned, and said, "Well, since we're not at the apartment, I used my fire from the Rebirth Gear to cook everything. I guess I had a lot more to vent than I thought."

Akeno said, "You are quite a catch, Isaac. I'm glad you're fighting for us."

"Same here. In fact, I have an idea. We'll call Clark after we eat."

Serafall then asked, "Who is this Clark?"

"He's my boss. I'm actually from an alternate universe, sent here to protect a student named Issei Hyodo. But now I have to worry about a civil war happening in the Underworld, but we'll be ready."

Rias said, "And how will we do that?"

"Simple. I have him get some training programs: Kiba, you'll be using the sword-fighting programs I've used; Koneko, the hand-to-hand training Isabel and I have been using, and for everyone else, I'll have Clark get some magic training programs ready."

Rias said, "Good to know the Wanderers will certainly help. We'll begin that in the morning, but for now, let's enjoy the rest of this meal."

-1 Hour Later, Isaac's POV-

We all finished eating, and Isabel and I cleaned up. I then sat on the couch with Rias, and Isabel sat next to Akeno, and I called Clark. He said, "Hello everyone. How are you recovering?"

Rias said, "I'm feeling better now. I think we all should do with some magic and combat training."

"Oh? But you're the Princess of Ruin. Well, there is always room for training. Good thing I already have programs I originally made for Isaac. I'll send them to Isaac's communicator. See you all tomorrow."

The screen shut off, and I said, "Well, good to know Clark has been planning this. I say we do some individual planning."

Rias came with me to my new room, and we fell asleep.

How's that for a fight gone wrong? Rias, Isaac and the group watched as the Rating Game unfolded to a slaughter! All Devils on Sirzechs' side, including Grayfia, were killed, and Sirzechs has vanished. Rias and Millicas were devastated, but now everyone will start training to take the Underworld back. In the next chapter, Isaac and everyone else will start fighting for their causes. Thanks for reading.
