Hey guys, Merciless Sun here with the next chapter of How To Start A World Tour! In the last chapter, Rias, the girls, and Genesis finally got to the Realm of Niflheim, and rescued Isaac and Koneko. And in this chapter, Isaac will be seeing what has changed in the 2 weeks he was gone, and Rias will take down the Renegade Fallen Angels.

-Bedroom, The Next Morning, 7 AM, Isaac's POV-

I just got woken up by Rias' alarm, and she got up while saying, "Good morning, darling."

"Good morning to you too. Before you leave, I need to make a full report to Clark. I think you'll need to hear this."

"Alright. I can't wait."

-Living Room, 20 Minutes Later, Isaac' POV-

We had all showered, and gathered on the couches. I pulled up the holo-screen and Clark said, "Good morning everyone."

"Good morning, Clark. I'm ready to give my report on the Khaos Brigade. When they captured me, I had found out they captured a Valkyrie named Rossweisse, and they're using her to take Ariz's Spirit to Surtur to destroy and then rebuild the Nine Realms as he sees fit."

Clark said, "Strange. He's normally not like that."

"It's because he has the other Parasite. I also discovered he was more irritable than before, and he got it when I first arrived here."

"Interesting….Alright, I want you to start training today. While you don't have your Sacred Gear anymore, you still have your connection to your Life Fibers. After that, you and Issei will get Xenovia, Irina and Kiba back. Next, Rias and Isabel, I want you to prepare for a full-on assault on the Fallen Angels. With how dire the situation has become, we need all the help we can get."

"Will do. Besides, I'm sure Akeno would like to see you again."

"Well, if that's all, I'll monitor your progress in the mountain."

"Thanks, Clark. Well, I'll see you later, Rias. Ready, Asia and Ravel?"

They both said, "Yes." Before we left, they gave me a belt with a flame pattern. We then left for the mountain.

-Mountain Field, 20 Minutes Later, Isaac's POV-

We had finally gotten to the mountain, and I found Sigrun waiting there with Sølvlys. I ran up to him and hugged his huge snout! "Hey! It's good to see you again, boy. I take it you've been taking care of him for me?"

"Only for the past few days. He and I wanted to come here to see your progress."

I grinned and said, "Thanks. Let's get this started."

I set up the communicator with a low level Close Combat program: Tatsuki from the Bleach universe. I was about to fight it when I saw Genesis coming up. I said, "Hey, Genesis. So why did Rias come to you?"

He set his stuff next to mine, and said, "Well, she said it's because they used this Mirror of Lucifer on a pond near here, and that power got transferred." He brought out his Sacred Gear.

"Incredible. I got my Sacred Gear because of that Mirror. I wonder if it can bring it back."

"I don't know what this thing can do, but let's try it!"

Before we did anything, I pulled up Clark on the holo-screen, and he said, "Hey guys, what's up?"

I said, "Well, Genesis and I were about to train when I came up with an idea. Could Genesis use his Sacred Gear to make the Mirror and maybe bring my power back?"

"Hm, I never thought of that. Let me scan you real quick." A small radar popped up, and a few seconds later, Clark said, "Alright, we have enhanced strength, immense defensive power, and magic redirection. Sorry, looks like there's nothing about summoning the Mirror of Lucifer."

I replied, "Damn. Well, I figured it wouldn't be that easy. Whatever. Lewis, let's do this!"

His eyes flashed, and the Life Fibers wove into the suit of armor. I then approached the Tatsuki program, and got into a fighting position. She ran to me, and when she was about to punch, I counted by grabbing her and tangling her in the Life Fibers. As I was going for a punch, I said, "Even without the Rebirth Gear, I will defeat anyone!"

The program shattered, and the Fibers went back to normal. Clark said, "Not bad. But I want to see how you really are against a Sacred Gear user. Genesis, get ready to fight him."

He brought out his Silver Reflection, and I got the armor out. We both started fighting. I started with a right hook, but then he blocked, and I was pushed back.

I had a grin on my face as I focused some Fibers into my arm. We both went for a punch, and when we clashed, we both got launched 30 feet and my Life Fibers were stripped away on the arm.

Asia ran to me, and brought out her Twilight Healing, but I got up, and said, "Thanks, but I'm fine. I'm ready to go again."

Lewis grunted and said, "Speak for yourself. You're not the one who has to repair these busted Fibers."

Clark said, "I like the enthusiasm, but Genesis ain't a fighter yet."

Sigrun interjected, "Your mentor is right. Besides, I wish to speak with you."

I replied, "I wouldn't mind that. Clark, what do you want Genesis to do?"

"I'm going to have him train. With the new updates on the Khaos Brigade, we need all the help."

"Good. I'll leave you to it, Genesis." Sigrun, Ravel and I then walked to her cabin.

When we got there, I saw Sirzechs and Grayfia in front of a pond with some holographic screens. Sirzechs saw me and happily said, "Isaac! Rias told me you came back. How are you recovering?"

"I'm doing ok. And I'm glad to see you're doing well, Grayfia."

She answered, "And I have you to thank for that."

"So what are you two doing here?"

"Well, with Rias having to get Akeno back, I decided to find where the Khaos Brigade is so we can plan an attack."

"Then I'll start for you. Please search the Realm of Muspelheim."

This computer voice then said, "Searching…..One Sacred Gear found! White Dragon Emperor!"

"Thought so."

Sirzechs said, "Vali…."

"Did you know about him?"

"When I became the new Lucifer, advisers warned me about him, but I was always a little wary about it. But if he has a Sacred Gear, then I'll need to pay attention to him."

"Yeah. Well, I'll be sure to help Rias set him straight."

"And I thank you for all you've done as her brother and the Devil King."

"So what is this thing?"

The voice called out, "I am the Vector of Yggdrasil. Who are you?"

"I am Isaac Fennis, former wielder of the Rebirth Gear. Could you please locate it though?"

"Searching…...No Sacred Gear located!"

"Damn. They must have forged him into the Sword."

Sigrun said, "By the Norns. Then we must act fast. Luckily, I have a secret communication line straight to Odin."

She went into her cabin, and a minute later, came back with a stone with a few runes in a circle, pressed the one on the right, and it swirled into a mirror that showed an old man. He said, "All these centuries, and I knew you would call. Hello, Sigrun."

"Hello, Odin. I'm calling because this man here has information."

I said, "Hi, Lord Odin. I recently got freed by Rias and your Valkyrie, Makellos in Niflheim. While I was there, the Devil, Vali Lucifer, had taken the Phoenix, Ariz, and is now in Muspelheim to forge him into the Sword. Surtur is about to destroy all Nine Realms."

"By my Beard. Have you found a Valkyrie there?"

"Yes, Rossweisse is being used to open up portals to the Nine Realms."

"Interesting. And have you heard anything from Loki while you were there?"

"Unfortunately, no. Is there any reason he would cause Ragnarok?"

"Well, he did kill Baldur."

Sigrun answered with, "I told you Loki was dangerous. Now Ragnarok is coming, but we have new allies to help defeat Surtur once and for all."

"Rias is about to stop the Fallen Angel civil war, and will get us some powerful allies back. Once I finish my training, I'm going to get some more allies back along with the most powerful Holy Sword, Excalibur."

"Excellent. Well, Sigrun, it's been good to see you."

She replied, "It's good to see you too, Odin."

The stone turned back to normal, and she put it away.

I said to Sirzechs, "Do you mind if I see your family? I haven't seen your father since I had to defend you."

"Of course."

We all got into a teleportation Circle to the Gremory Estate.

-Gremory Manor, Isaac's POV-

We had arrived, and I went to an upstairs balcony looking over the estate. I saw a glimpse of lightning and explosions past a mountain range. "Must be the civil war. I thought once Raze was defeated, all this would be over."

A man then replied, "If it were that easy, then the Angels would have surely defeated us during the Great War."

I turned around and saw Zeoticus with Venelana. "Good to see you again, sir."

He smiled and replied, "And it's good to see you alive and well."

I held up my right arm that had a scar in the elbow area. "I wouldn't go that far, but I'm always ready for a fight."

"Good, because these next few days will test you."

"Right. But I would like to talk to you about a few things."

"Of course. I'll have a servant get a few refreshments."

We walked down to the main hall.

-Civil War Battlefield, Rias' POV-

Isabel and I just arrived in the main Loyalist camp, and a male Fallen Angel held a Light Spear to my throat. "Halt! State your business, Devil!"

I surrounded my right hand in Destruction Energy, moved the spear away with it, and said, "I'm here to speak with Azazel, Baraqiel and Akeno."

He put away the spear, and brought me to a large tent. We saw Akeno, Baraqiel and a few other Fallen Angels surrounding a table with a war map on it. Akeno saw me and said, "Rias! It's good to see you!" She ran to me and hugged me.

I hugged her back and said, "It's great to see you. And I have some great news: Isaac is back!"

"When did you rescue him?!"

"We got him out yesterday. You'll see him once we defeat the renegades. Who are they?"

Baraqiel said, "They are Dohnaseek and Kalawarner, former allies of Raynere. After learning she had been killed by Isaac, they killed a few Loyal Fallen Angels and declared war. I asked Sirzechs not to interfere, as it is our affair. So why are you here?"

"It turns out this whole coup is orchestrated by the Khaos Brigade, and we need Akeno to help defeat Vali."

Azazel then came out, and said, "I knew you would save him soon. Any damages to him?"

"He had the Rebirth Gear taken away by Kuroka."

"How is that possible? I'll have to look into that."

Baraqiel said, "Now that the reunion is out of the way, let's end this coup. We need to defeat them before they can release Kokabiel."

We all brought out our wings and flew to the battlefield. I saw a whole squadron get defeated by Dohnaseek, a tall man with short black hair, dress shirt and pants, and 2 black wings. Azazel and I flew to him, while Akeno and Baraqiel carrying Isabel, saw Kalawarner, a woman with long navy blue hair, maroon trench coat and 2 black wings. Good luck guys.

-Gremory Manor, Isaac' POV, 4 PM-

I was sitting with Ravel and Sigrun and across from Venelana and Zeoticus, and they were telling me the history of the Royal Families. Zeoticus said, "It had been about 100 years since a Devil King had been born into our family, and it seems not every family was happy about it."

I replied, "Don't I know that? So I noticed the battle is almost a little close to home. Why is that?"

"Well, we have received word that this latest raid is to release Kokabiel."

"Damn. Well, I know Rias can handle it."

Venelana then said, "Indeed. And how is your dragon doing?"

Sigrun replied, "I've been taking good care of his Vana Dragon. How did you come upon him?"

"Well, I am friends with Frigg, and she allowed me to raise a few Dragons imported from Vanaheim. So I heard from her that Ragnarok is coming."

I said, "Yeah, and unfortunately, they now have the sword, which was my Sacred Gear. But I'll get it back before Surtur uses it to destroy Asgard."

Sigrun said, "Actually, it's not him we should worry about. When Thor defeated him 3000 years ago, his anger split from him, and became a new entity, Surtas, his daughter."

"I see. It doesn't matter. I'll get through to Ariz and get him back."

Just then, we felt a huge explosion! A guard ran to us and said, "Lord Zoeticus! Lord Lucifer! It seems Lady Rias has defeated the renegade Fallen Angels! But prisoners from the mountain prison have been freed!"

Sirzechs said, "Then we must go to the prison. If the Phenex brothers are freed, it'll be a disaster for the integrity of the Underworld."

I stood up and said, "I'm coming. I need to stop Riser."

Ravel added, "I'm coming along. He is my brother, and you may need my Phoenix Tears."

Grayfia then said, "Excellent. Let us go then."

She then teleported us to the battlefield.

-Battlefield, Rias' POV, 5 Minutes Ago-

I was fighting Dohnaseek with Azazel when he threw his Light Spear at me! I made a giant ball of energy and shot it at him. It broke the spear and blew up in his face. He slammed into a nearby mountainside and had rocks fall onto him. "Now that that's done, let's help Akeno."

As I brought out my wings, I saw a Spear stab through Azazel. He fell to the ground, and Dohnaseek, who was now missing an arm, burst out of the pile of boulders and rushed to grab me by the throat! As he did, he threw me towards Akeno, who was 5 miles away, and I slammed into her!

We both got up, and she said, "I see you're having trouble."

I got angrier, my eyes glowed red, and I said, "Not for long!"

I focused energy into both my hands, and said to both Akeno and Baraqiel, "Get those two in front of me, then run."

Both Dohnaseek and Kalawarner rush to me, but Akeno and Baraqiel stun them with Lightning Magic, and run out of the way. I then release my hands, and the energy bursts forth into an immense explosion! "Dark Wave Nova!"

However, as the explosion vaporized the Renegades, it also destroyed the eastern mountain wall connected to the prison. "Oh no….. The prisoners are free!"

Azazel slowly came to us and said, "You have to do something. The balance of the world can't handle the return of the Phenex brothers and Kokabiel."

"Right! Akeno, head over to the Family Estate and tell Sirzechs!"

"Of course, Rias." Akeno and Baraqiel then teleported to my home.

Azazel said, "Good, now I'm going to get this stab wound checked out, see you soon, Rias."

"Thanks, Azazel!" I then ran towards the prison!

It seems the Phenex Family keeps on coming like a stray cat. Isaac had seen what Genesis is capable of, and went off to the Underworld just in time for the Phenex brothers and Kokabiel to be free, and Rias had been a bit reckless to get Akeno back, and by killing Kalawarner and Dohnaseek, she had set them free. and in the next chapter, Isaac will try to defeat Riser. Thanks for reading!

-Author's Notes-

Well, another month, another chapter. Work has been pretty hectic, I finally have a girlfriend, but I'm doing what I can to make new chapters, and I've been brainstorming something major to this series, but first I will need to establish what the Wanderers are. I thank you all for reading, and I hope you continue to read more as I make more.
