Hey everyone, Merciless Sun here with the next chapter of How To Start A World Tour! In the last chapter, Isaac discovered he still had some power, and Rias defeated the Rogue Fallen Angels, but in doing so, destroyed the Underworld prison wall. In this chapter, Isaac will try to help defeat the Phenex Brothers once and for all

-Battlefield Near The Prison, Isaac's POV-

Grayfia just teleported us outside the prison, and I saw Rias run towards it! I said to Ravel, "Alright, we gotta catch up to Rias before Riser gets to her! Thanks for bringing us here, Grayfia, but I'm sure Sirzechs needs you."

She smiled and said, "Of course, Master Fennis."

We ran towards the prison, and I pulled up Clark on the holo-screen. He said, "How did it go in the Underworld?"

"Well, apparently Rias and the others won, but Rias destroyed the outer prison wall, so Ravel and I are rushing over to her before Riser gets to her."

"Damn. Lewis, what's the status of the Life Fibers?"

He replied, "They aren't rebuilt yet."

I said, "I'll handle this on my own, besides, this is long due."

We just got to the entrance. "Alright, wish us luck."

"Will do, Isaac." The screen shut off.

We then entered, and came across a corridor that branches off. Ravel said, "I'll handle my brother. You take the right path, and it should take you to Lady Rias, who is going towards Raze. I sense her presence down there."

"Thanks, Ravel. Be careful."

Some flames surrounded her, and said, "Don't worry about me, I'm a member of the Phenex Family too!" She then ran off on the left path.

And all this time I thought she just went shopping with Asia. Oh well. "I'm coming, Rias!" I then take off running on the right path!

-Right Path, Rias' POV-

I felt a couple presences enter the prison. Feels like Isaac and Ravel. Are they up to it? A few Middle-Class Devils bust out of their cells, and try to attack me, but I just hit them with a Destructive punch, and they explode.

I then run to Kokabiel's cell, where I see the Nova destroyed the back wall, and part of his back was incinerated. "At least the Fallen Angels have lost the Renegade General. Now where's Riser and Raze?"

I then hear a man behind me say, "And which one did you miss: The real King of Hell, or my little brother?"

I turned around and saw Raze in his cell. "Hello, Raze. I take it the safeguards have weakened you and Riser?"

He then broke through the bars, and replied, "I wouldn't be too sure of that if I were you. Your attack sent damage throughout the entire prison. I'm sure Riser will be over once he deals with my sister and your pathetic Human lover."

"I won't let him touch them!" I then punched him, but he countered and threw me far into the corridor! He then rushed to me, and grabbed me by my shirt. I was in an area surrounded by other cells, with the prisoners reaching out.

"You've increased your power quite considerably, my dear Rias. But surely, you see it means nothing compared to the might of the Phenex family!"

Just then, the wall to my left burst open, and I saw Isaac fighting Riser, and we all felt slightly weaker!

-Isaac's Path, 3 Minutes Ago, Isaac's POV-

I was running down the path towards Rias when I felt some rumbling! "Dammit, what now!?"

The surrounding walls burst open, and 5 Devils came towards me! "This is for Lord Riser!" I drew my sword, and a small warm feeling swelled up in my arm. I then slashed at them, and they immediately fell to the ground, screaming!

"I don't have time to deal with you. I must deal with your boss."

Then behind me, I heard a man say, "Did you miss Riser?"

I turned around and saw Riser. "What happened to Ravel?"

"Riser left her in my cell. Hopefully it'll remove your Human stench. Now Riser will remove you from mine and my beloved's life!"

He then tried to punch me, but I blocked it with my arm. "I have learned quite a bit since the wedding. And you'll see what I got!"

I took his arm into a lock, threw him into a nearby wall, and dashed into him. He crashed through it, and as we went through, I saw Rias and Raze. We kept going until we came out to the battlefield from the huge hole made by Rias.

He then elbowed me in the shoulder, and I stopped. He said, "You have improved quite a bit, but it means nothing!" He then surrounded himself with fire.

I then took a deep breath, got in a defensive stance, and felt the same warm feeling in my stomach. What is this? And why did the Devils scream out? It wasn't like that during the wedding.

He charged toward me, and I started blocking every attack, and I could see him wincing after every block. He threw a punch covered in fire, but I grabbed it with my free hand, and he screamed and backed away! "What is this power!?"

I ran towards him and I started wailing on him! "Why do you never learn!?"

He finally hit the ground, and I turned around and walked towards the mountain. He slowly started to get up and launched a beam of fire at me! I tried to dodge at the last second, but I got hit in the face and blasted back 30 feet!

I was about to get up when he came over, grinned, and kicked me in the face, which made me pass out.

-Gremory Manor, Akeno's POV-

I just made it to the entrance hall of the manor with my father, and saw the whole Gremory family. "I was just sent by Rias to inform you that the eastern prison wall was just destroyed. We're going to need all hands on deck for this fight."

Sirzechs and Grayfia stood up, and he said, "Very well. We shall fight, and you shall get Isabel and the other allies. I believe they are still training on the mountain in the Human World."

"Yes, sir!" I then teleported to the mountain.

-Mountain Training Field, Isabel's POV-

I just got up to the field where I saw Genesis and Asia. "Hey, everyone. Where's Isaac at?"

Genesis replied, "He went to the Underworld with Sigrun a few hours ago."

Issei just came in. "Hey Genesis. It sure is quiet around here."

Akeno then teleported in, and said, "Everyone, we have a problem! The Underworld prison is nearly destroyed, and the Phenex brothers have escaped!"

Issei asked, "What's going on?!"

I answered, "Rias' ex-fiance is about to rule the Underworld. Let's go!"

Asia came with us, and Akeno teleported us to the Gremory manor.

-Gremory Manor, Isabel's POV-

We just arrived when we saw the Gremory family. Sirzechs came to us and said, "Hello everyone. Riser is on his way now. I don't know where Isaac, Rias or Ravel are though."

I said, "Crap. Ok. Genesis, you're with me. Issei and Asia, I want you to protect the others here."

Sigrun asked, "Wait, where is Makellos?"

I replied, "I saw her in the cabin on the way to the training field."

"And that girl wants to be a full-fledged Valkyrie…" She pulled out a runestone, touched the rune in the center, threw it into the yard, and in a flash of light, Makellos appeared, sleeping.

I walked to her, and said, "Makellos, please wake up. We're about to be in a fight."

She woke up, yawning, and brought out a silver spear with a white spiral pattern.

Sigrun asked, "And when did Odin give you Gungnir?"

She giggled and answered, "I might have asked Brok to make a new one."

"I don't even want to know what you did for that."

Sirzechs said, "Everyone, please focus. Here comes Riser…..Oh no."

He came up and was dragging Isaac by his hood. He threw him in front of us, and said, "This is what happens when we don't follow our traditions! We trust Humans to help us, and they can't even defeat my greatness! My brother will return with my bride, but for now, Riser shall create his new empire by killing the so-called Devil King, Lucifer!"

I then got Ice Magic ready, and Genesis got his Sacred Gear out, and we both rushed him. Riser grinned and launched a fire blast at us, but Genesis blocked, and it got reflected back to him! He got hit by it, but instantly healed. "You keep doing that and Riser will get bored!"

He then grabbed Genesis' throat! I then dashed to him and started rapidly punching him, but the fire started to get intense. I was about to switch to Lightning Magic when he threw Genesis to me! We were launched back to Sirzechs, who we landed in front of, then passed out.

-Akeno's POV-

We just witnessed Isabel and Genesis defeated by Riser when Raze came over with Rias over his shoulder, unconscious. He said, "Brother, I have returned with Rias." He then laid her between them.

Riser then grinned, and punched Raze so hard that he crashed into the mountain, and it crumbled into pieces! "A shame my dear sister was in there, but it is such a small price to be the True Devil King!"

I got angry that I was about to charge at him, but Makellos charged at him and stabbed him in the heart with Gungnir! As she did, I looked over to Issei, who had the Boosted Gear out, but was so scared that he was frozen. Riser coughed up blood, and right when he was about to fall, he smiled, broke the spear, and punched her away!

Sigrun said, "But how?! That spear is the greatest weapon of the Allfather!"

"Nothing is greater than the glory of Riser Phenex!"

We all then heard, "BOOST!"

We turned to see Issei, who was so angry, the air was distorting around him! "Rias is not yours to own, you dick!"

The Boosted Gear shined, and he rushed to Riser and started punching him, but it looked like nothing was working! Just then, Isaac started moving a bit, and the next punch made Riser fall over! He then slowly stood up, and right when Issei was about to punch him again, he grabbed the fist, twisted it, and threw him to Sirzechs, who caught him, but due to the force,he got launched into the manor!

"Do you see now!? Even with the weak power of these pathetic humans, and the 'Devil King,' only one can come out on top! Now bow to your new ruler, Riser Phenex!"

We all started to bow, and he said, "Excellent!" But he started to fumble, and fell to his knees. "HOW!?"

We all saw a faint glow, and looked to Isaac, who was now glowing with Holy Light, and rose back to his feet. He then spoke with a calm and echoing voice. "Riser Phenex, your judgment has come!"

-Isaac's Mind, 5 Minutes Ago, Isaac's POV-

I was just knocked out by Riser, and I woke up in my mind space. As I was stumbling through the dark, I saw a faint white light. Is that what I think it is? I ran towards it, and it was a small ball of white light. It then blossomed into the Archangel, Michael!

He said, "Greetings, young Isaac. I have arrived with a gift."

"What is it?"

He put his hand on my forehead, and my whole body started to shine, with the scar on my torso shining the brightest. "What am I now?"

"You are a conduit of my Holy Energy, created by a Devil that extracted the Phoenix, and like the Phoenix, you have been reborn: Reborn as my Morningstar."

"Incredible! But why give this to me?"

"Because you have been marked for greatness, not by me, but by God himself, which seems impossible. But that is for another time. Now go. I believe you have an escaped prisoner to defeat."

"Right! Thanks Michael, I won't let you down!" I then left the mind space, and woke up.

-Front Lawn of Gremory Manor, Isaac's POV-

I finally woke up, and felt the Holy Energy spread through my entire body as I rose back to my feet. "Riser Phenex, your judgment has come!"

Everyone was cheering as Riser gritted his teeth. "Even with your power, you will never defeat me!"

"That does not matter anymore. Your disregard for the peace all have fought hard to create has not gone unnoticed, and the Archangel Michael has made me his Morningstar, his sword, to strike you down!" I then radiated more energy, and he started to cough up blood.

He got angry, and fire started to swirl around him. "You think you can defeat me as a 'Morningstar'?! You couldn't do that with your Sacred Gear!"

He then dashed to me, and punched me in the jaw, but I was unfazed. I then punched him back, and he fell to the ground instantly, screaming! The Light intensified, and while every Devil fell to the ground, a Halo formed atop my head.

He screamed to me, "You cannot defeat me! I am IMMORTAL!"

"It doesn't matter. Fate is no longer on your side. Now come face your destiny." I got in a fighting stance.

Even more fire surrounded him, and when he rushed to me again, he went to punch me, but I countered, put his arm in a lock, and punched him through the chest! The fire then went out, and Riser passed out. I let go and said, "It is done. Sirzechs, please come get him. He won't fight anymore."

I took a deep breath and the Holy energy left. I then went to Rias and picked her up. Akeno then came to us, and said, "I didn't know you had this power."

"Neither did I, but it seems Kuroka left me a gift," I lifted up my shirt to show the scar, "and Michael gave me the Light as his Morningstar."

Sir Zechs came to me and said, "Once again, you saved our family from the Phenex family. Riser isn't dead, but he's in shock. Now I must get Ravel, she was left in his cell, and even though she's immortal, I know she needs help."

"Thanks. So what will you do about the manor?"

Zeoticus chuckled and said, "Don't worry about that. We have a few other homes nearby. In fact, come rest with Rias there then you can leave when you are ready."

I smiled and replied with, "Thank you so much, sir. You and your family have done so much for me, and I will protect Rias and you no matter what."

"That is truly appreciated. Let us go then."

Akeno then picked up Issei and Genesis, and Grayfia picked up Isabel and Makellos.

-Gremory Vacation Home, 10 Minutes Later, Isaac's POV-

We finally got to the home, and when we entered, I felt the Holy energy surge. Dammit, not now please. I saw Rias wince in her sleep, but I calmed down and it went away.

We entered a huge home with a setup similar to the manor. Venelana said, "Go up the stairs, and it'll be the third door on the right."

"Thanks." I smiled and took Rias up to the room while Akeno and Grayfia took the others to another room.

I laid her on the bed in the very large room, and tucked her in. As I left, I said, "Rest well, Rias, and I'm glad I can protect you again."

I went back down to the main hall, and saw everyone sitting down on couches. I sat down, and said, "Since the biggest Devil threat just got taken out, I think it's time to call Clark, and let him know what happened."

As soon as I said that, Azazel came in with bandages on his head and torso and said, "I think I might need to be a part of that, Isaac."

I said, "Oh, hey Azazel, come join us."

He sat down next to me, and I set up a large holo-screen with Clark on it. "Hello Isaac. I saw some fights from inside the prison, but as soon as I saw outside, some crazy lightshow happened, and next thing I knew, you stood over Riser's body while the whole mountain prison was destroyed!"

"Well, I fought Riser, and lost, until Michael gave me Holy power, and made me a Morningstar. I then severely injured him, and Sir Zechs took him somewhere. Rias was fighting Raze, but got defeated. She was taken to the Gremory manor, and as soon as Raze brought her there, Riser punched him to the mountain so hard that it collapsed!"

"Damn. Let me check the drones to see how bad that damage is."

A minute later, he said, "Damn. Not only are all the prisoners dead, but so is Raze. And it looks like Sir Zechs just found Ravel, and….. She's alive!"

We all breathed a sigh of relief, and Akeno said, "The Phenex family now has a new life."

Clark then asked, "Ok, so that answers the question about the Phenex family, but what about everyone else?"

Akeno answered with, "Well, just about everyone was knocked out, and when Issei fought, his power had increased very quickly. Unfortunately, Riser was too much for almost everyone."

"I see. And Isaac, you said you have Holy powers now?"

"Yeah." I lifted up my shirt, and when the scar was down, it glowed a tiny bit, and every Devil was wincing. Crap! I then calmed down, and it went away. "Sorry about that. I don't exactly have control over it yet. I might have to talk to Michael later."

"Interesting. Well, you'll be well equipped to take on Freed tomorrow with Kiba and the Exorcists. I'll see you and the others when they rest up. Well done, Isaac."

The screen shut off, and I said, "Well, good to know things settled down here a bit. I'm going to be in Rias' room and try to control the Light. I will see you later."

I got up to the room, and saw Rias still sleeping. I smiled and sat on the end to meditate.

-Mind Space, Isaac's POV-

I looked around, and saw Ragyo trapped in the Life Fibers. She was struggling, and said, "So you do remember me?"

"Well, I didn't, but I might as well finish this."

The Holy light started to shine, and I charged at her! But once I laid the first punch, I heard Rias screaming! "What did you do!?"

She grinned and said, "Oh, I didn't do anything! You should really be careful with that energy. Some Devils may not like it." She then vanished while laughing.

No! I then left!

-Rias' Room, Isaac's POV-

Everyone rushed into the room, and I woke up seeing Light shine out of my scar, and Rias grabbing her head in pain! I tried to calm down and get the Light to stop, but it wouldn't work! I then ran out of the manor, and when I passed by every Devil, I briefly saw them falling over in pain.

I went to the courtyard and yelled out loud, "Why can't I stop this!?"

Asia then came running to me and said, "Here! I'll help!"

She then put her hands on my scar and started praying. It slowly went down and her Rosary then started to dimly light up. Akeno then came to us, and asked, "Is everything ok?!"

I replied, "Sadly, no. But with Asia with me, I can be around Devils. How is everyone?"

"They're fine now. Let's get you back to Rias."

"Ok….." I kept taking deep breaths to stop the Light, but as I passed by a Devil, they had a pained look on their faces.

We got up to Rias' room, and she was sitting up, and tried to smile when she saw me, but started wincing at the pain. Asia and I sat down, and Asia started praying more.

Rias asked, "What happened, and what's with the Holy Light?"

I smiled, and answered. "Riser is done. But he killed Raze, and left Ravel in his cell. I beat him with a new form called Morningstar, given to me by Michael. However, I can't control it. When I tried to, there was a mental block, and it went crazy. But Asia is siphoning the energy into her cross."

"Where is Ravel now?"

Sirzechs then came to the door with her in his arms. "Right here. She had a few scrapes, but her healing factor should be working soon."

"Great. Let's see how the others are doing."

Venelana said, "Then follow me to the dining hall. They are recovering there."

We followed her down the hallway into the foyer, where there was a huge hole from Sirzechs and Issei being launched.

We then entered the dining hall, and found Isabel in a chair with bandages on her head and right arm. Genesis and Issei were laying on the table. They sat up, and Genesis said, "I hear you took Riser down. Nice."

"Yeah. Thanks for fighting for Rias. It's good to know there's a good friend to fight with. Are you ready to head back home?"

"Yeah. I need some rest. How about you, Issei?"

"Only if I can be with a girl."

I chuckled and said, "Sorry, they're with me. I'll see you next time in Hell."

"Alright I'm coming!"

Ravel then woke up and got put on the ground by Sirzechs. "What happened? Where are my brothers?"

I said, "Everything is finished now. Riser is imprisoned and will never bother us again, Raze however is dead. He got launched into the mountain by Riser."

"Oh……"

Rias asked, "Are you ok?"

"Yes, Lady Rias, just surprised. We were supposed to be immortal, but if Raze died….."

I said, "It was because he was near me when he got hit. I now possess the Holy Light."

"Then how come I'm not in pain?"

I motioned to Asia. "She's constantly praying to absorb the energy. But she can't keep it up through the night."

Asia said with effort, "I have a Rosario that can help absorb the energy, Xenovia gave it to me before she left."

"Great. Now let's go home. We need to see how Koneko is doing."

Everyone is gathered, and Rias makes a teleportation circle, and we arrive at the cabin.

-Sigrun's Cabin, Isaac's POV-

We arrived here, and Sigrun said, "Well, it was certainly fun to see a war end. It reminds me of the war with the Vanir. I'm going to accompany your Vana Dragon."

"Thanks Sigrun. We'll come by tomorrow before Issei and I have to help out the Exorcists."

"You're welcome, young man. Makellos, please stay with this band of warriors. They'll help you become a true Valkyrie."

She gladly replied, "Of course, grandmother."

She then went into the woods toward Sōlv. I said, "Well, I can't wait to see how Koneko is. When we were in Ymir's Castle, they were doing some chants to undo her limiters, and something didn't feel right."

Rias replied with, "I sensed it when you both got back. We'll see what's wrong with her. Have a good rest of your day, Genesis and Issei, and remember to be here at 9 for your fight tomorrow."

Issei then sighed. "Ok…."

They left, and she teleported us all back home.

-Isaac's Home, Isaac's POV-

We got home, and Koneko was still sleeping. Rias sat down near her and asked, "Koneko, are you okay?"

She then woke up, and when she saw Rias, her eyes went red and she brought her claws out. I then got in front of her and said, "Koneko! It's me. You don't have to do this."

She then swiped at me, and as the claws hit my chest, she felt the Holy Light and ran off! Asia then used her Twilight Healing. "Dammit. I'm sorry we lost Koneko, Rias."

"As am I, dear." She came in for a hug, but the Light hurt her.

I sadly said, "You should sleep in my room for the time being. I don't want you to get hurt from this. I'm going to go train and try to get control of this."

Asia came with me, and we walked out.

-Forest, 1 Hour Later, Isaac's POV-

We had arrived, and I saw Sigrun with Sōlvyvs. "Hello Isaac, why is it just you and Asia?"

"My Holy Light is getting out of control, I just need to get away from her. And her friend Koneko just left in a rage."

"Was she the young cat woman?"

"Yes! Have you seen her?"

"I saw her run by in a blur 20 minutes ago."

"Damn. Now we don't know where she is."

I got a call from Rias. "Hey dear, have you heard anything about Koneko?"

"Sigrun said she ran by about 20 minutes ago."

"Oh. Well, I called one of our allies, and he said he could help with your energy."

I then spoke in a happier tone. "Who is it?"

All of a sudden, the sky split open, and we saw Michael descend to us. "Greetings, Isaac. Rias said you're having a problem with your Morningstar powers."

"Yes. I just can't control it, I'm around too many Devils and it just keeps coming out."

He then put his hand on my forehead, and I felt it go away. "I have taken away some of the energy, but it's not gone forever. You must master this on your own."

"Thank you sir!"

I then picked up the phone and said, "It's gone for now, I'll be home soon. Good-bye Rias."

She happily said, "Good bye, dear."

Michael said, "When I removed some Light, I found an unholy presence within you."

"Yeah, it's a hallucination of my ex-girlfriend's mother. I'm going to get rid of her tomorrow."

"Good, because once you do, then your Holy Light will be in your control."

"Great. Well, I'll see you later. Bye, Michael."

"Goodbye, Isaac." He then flew back to Heaven.

Sigrun said, "Well, I'm glad you have your new ability taken care of."

"Me too, I was worried about it getting out of control. I'll be going home, so bye, Sigrun. I'll see you and Sōlvyvs tomorrow before we fight Freed, the Mad Exorcist."

Asia and I walked back to the house.

-Isaac's House, 1 Hour Later, Isaac's POV-

We walked back, and I saw Rias and the others talking to Clark on the holo-screen. He said, "Nice of you to join us. How are you feeling?"

"I have a little more control now. Have you seen anything in Muspelheim? That's where Surtur, Surtas, and Vali should be."

"Let me see….. They have the sword."

We then saw the Fire Giants, Vali, and a tall man with long silver hair and 3 sapphires in his forehead.

Makellos said, "That's Loki. Grandmother told me he was bad news, and it seems with Rossweisse and I gone, he is now starting Ragnarok."

We then see Surtas hold a longsword with a red blade, silver handle, and orange Nordic runes. Damn, they actually turned Ariz into the sword.

I take a deep breath, and sigh. "Ok. Any idea on when they will strike?"

"Not yet. Makellos, is there any way you can get us there?"

She replied, "No. They are using Rossweisse to block us from going there."

"Damn. Then it seems we'll have to wait until they get to Yggdrasil. Meanwhile, you and Issei join Kiba, Xenovia and Irina for the final assault against Freed Selzan before he gets the final piece of Excalibur in Ireland."

"You got it, Clark." He then turned off the screen.

Rias then hugged me. "I'm glad the Light is getting better."

"Me too. But I have a confession. When Kuroka took away my Rebirth Gear, I started getting a ghost of Ragyo in my head. She nearly took me over, but the Light is fighting her. That's why it keeps hurting you. When I get back from Ireland, I'm going to get rid of her once and for all."

"Thank you for telling me." We then kissed, and we all sat down on the couches.

"So, what record do you want to start?"

Rias said, "Clark assigned a new multiverse to review, the Infinite Marvel. We wanted to start it when you got back to us."

"Sounds great. Let's start with the first chronological entry, Captain America."

We then watched the record of Steve Rogers fighting this dictator named Red Skull.

-2 Hours Later, General POV-

Everyone is asleep and sleeping in the living room when a red aura surrounds Isaac. He shivers a bit, but that's when Light shine from his scar. It then dissipates. The Light is gone, and he pulls Rias and Asia closer.

Well, Isaac now has an incredible power against Vali and the Devils, but it's a double-edged sword since he has 2 Devils with him.Riser is officially defeated, Akeno is back with the group, and Isaac has become Michael's Morningstar! in the next chapter, Isaac and Issei will try to stop Freed Selzan from completing the Holy Sword, Excalibur. Thanks for reading!

- Author's Note-That's another chapter done. We're halfway done with this story, and we've got a lot more coming! Now I said that I want to start a huge story, and it will involve many series, such as Seven Deadly Sins, DanMachi, and a return to the Kill LA Kill universe from Anarchy Clothing! I'll start that once I'm done with the next 6 chapters. Thanks for reading and I'll see you next time.
