Came the weekend as school days pass in a flash.

I walk back to school to go to the Research Occult Club. The night was very bright unlike the darkness in the past. The streets are full of lights, and the air stinks. After a while I arrived at the club. Without knocking the door, I opened it. My brother and everyone was here.

Shiro: "Good morning everyone? Also good morning Sister-in-laws." Before anyone could reply. "Wait a minute? I need a nickname for all my sister-in-laws."

Everyone in the room was confused, except Rias, and Issei.

Akeno, Kiba, and Koneko: Shocked from my appeace. "What do you mean sister-in-law, and who are your sister-in-laws?"

Shiro: I mean aren't Rias, Koneko, and Akeno my sister-in-laws? With an innocent face.

Rias and Issei's faces turn red and have a little bit of sweat on their head.

Rias: What are you doing here, Shiro-chan?

Shiro: I am here to check to see if, If my niece or nephew is coming or not.

I brought out a picture of them hugging, and Issei turned even more red and got a little bit mad at me.

Issei: Stop fooling around Shiro. Can't you see that we were not in that relationship as you saw.

Shiro: So you don't mind if I take her away from you then? You got yourself a few wifes and you should be happy aniiki. Also, Aniki should know better whether you like her or not.

My face turns ferocious like an ancient beast ready to kill. The room got colder as my aura rose. Kiba pulls out his sword while Koneko jumps in front of Rias.

Shiro: How can you get a girlfriend with the way you act now? Rias like you, and that's why she turned red. Why are you so dense?

Seeing the mood of everyone and how work up everyone is. I no longer have time to waste. My face turns serious and my aura changes.

Shiro: Sister-in-law, how do you get into the underworld, since I might get into the wrong underworld or hell. I need to talk to somebody.

This time Rias face was not red, and became serious. She thought in her head, who is she going to talk to? Is it my brother?

Rias: Who the person you're going to talk to Shiro-chan. If you tell me who you are going to talk to. I will take you to the Underworld and where you want.

Shiro: Fine! Have it your way. I will just take you with me, and you will know who I am talking to. Now show the way.

Rias pulls out a card that will cast a teleport spell. It will teleport everyone inside the spell to the Underworld.

Stepping into the circle spell, both me and Rias were teleported to the Underworld in front of Gremory mansion. It was a fine piece of artwork. The material used to make this mansion was extremely rare. The sky in the Underworld was just like Earth, but I could tell that it was naturally made.

Grayfia opens the door to see Rias with an unknown boy with golden armor.

Grayfia: Welcome home madam, and who is this boy, madam.

Shiro: Who I am is not important. What is important is that I have words to talk to your husband and my sister-in-law's parents.

Grayfia: Not just anyone can meet with them, young boy. Also you're being very rude here.

Stolen novel; please report.

The sky turns dark with the silent as it could feel the horrible power of us.

Shiro: Tell them they have 1 minute to meet me, or I will destroy the Underworld. Also, I am not a boy. I am a God. I came here for my sister-in-law.

Grayfia was in deep thinking, and thought it had to do with Ria's marriage. So Rias married this guy's brother?

Grayfia: Who is your sister-in-law? She said it knowing that Shiro was going to answer with Rias.

With one word. I said, "Rias". Then I release my aura. My aura became visible and looked reddish and feel as the sun appear in the underworld. As the aura becomes bigger, the larger the pressure is. The pressure spread throughout Gremory territory and made a lot of devils fall to the down. They are stuck to the ground and unable to move. The weaker devil was coughing blood. Grayfia seeing this pressure, now she knew something serious was going on. Her face changed as I hurt her son by my aura alone.

Grayfia: Stop! Or else you leave me with no choice but to kill you! Her face was ready to kill me.

Rias: Stop it!!! Shiro-chan!

Soon the aura disappears, and everyone in Gremory terrority knows that something might happen. Grayfia went to grab her husband, and I walked with Rias to her parents. Rias couldn't believe the amount of power I hold. While Grayfia wasn't surprised, "Based on the aura alone, he is in the top 200 strongest being. Maybe even in the top 100."

Shiro: I may not be able to beat you and your kind now, but killing me will be hard.

I laugh with a gesugao face(Evil face kinda). The clock was running while Sirzechs Lucifer teleported after sensing my power. Sirzechs and his peerage appeared behind me due to the teleport spell and saw me looking at them. Their facial expression was not friendly, and was wondering what happened here.

Grayfia: Sir Sirzechs, That young boy wanted to talk to you, Zeoticus-san, and Venelana-san. She wanted to talk about Rias being her sister-in-law, and maybe to cancel Riser and Rias engagement. I presume.

In the next moment, I pull out my spear and slash at Sirzechs. When I move, so did his peerages cames to block the attack. The spear was stop, but Souji Okita hand was numb from blocking the spear with his sword.

Shiro: That some nice reaction you guys have.

That didn't stop Okita from counter attacking. He slash the next second, the edge of the sword to be grab by Shiro left hands.

Rias parents finally arrive to see Shiro losing a small amount of blood that barely visible, and only to stop seconds later. His sword technique fail to kill. Everyone was shocked that Okita fail to kill a stranger, as he was one of the strongest in the underworld.

Shiro: If I went for real, I would have killed you since I don't fight like that. Since everyone is here, I want to cancel the marriage of Rias and Riser. Since she will be marrying my brother instead. I shall not take no for an answer. My brother is the welder of the Welsh Dragon and it only a matter of time for him to grow stronger. Also he so dumb not to take advanage of my sisiter-in-law and get me a niece or nephew. Also he is the pawn of Rias too.

Sirzechs: He looks at Rias with a sense of guilt for making the engagement. Rias, do you like that pawn of your?

She couldn't answer yet, but she knows that she didn't want to marry Riser in her heart. Before Rias could reply.

Shiro: Don' worry, I know that she will like my brother in the future. In fact she will be jealous of him being surrounded by girls. All dragon hosts attract a lot of girls, and you should know it by now. If my brother actually trained, he would be very strong by now. Too bad, that Rias has to train him. By the way, do you have some treasure wines?

Sirzechs: I guess you are right. Dragons do attract a lot of females, especially those twin heavenly dragons. For the Treasure wine, I possess a few. I can give you one if you tell me who you are.

"Let me taste this wine first. If it is not good, I will not tell you anything of me." I said.

The tension in the air was strong as Sirzechs handed me a bottle of wine. I took the bottle and opened it. Smell the fragrance, and grab a cup from the gate of babylon. I pour the wine into the cups and drink it all in one go.

Shiro: It is quite good, but still a pale incomparasion to my wine. Still it's great to drink different wine everyday. I then store the wine into the Gate of Babylon. (By the way, Gate of Babylon refills the wine collection to how I put it into the gate. For example: If the sword I use was broken in battle. When it returns to the gate, it will be repaired already. So the wine will always be full when I grab it out again, it will be in the same state that I put it in.)

Sirzechs: Now can you tell a little about you, Shiro-san?

Shiro: It won't be fun if I tell you! I am not one, but many into one. Now that all, Goodbye.

I then summon my Vimana: Throne of the Heaven-soaring King. It was time for me to go away. Everyone had a surprise reaction to my vehicles. It was a golden and emerald ark. I then jumped on the Vimana and sat on my throne. Suddenly the vehicles move at godlike speed and disappear.

What kind of vehicles was that? They couldn't figure out my vehicle's name, but If Indra was here. He would know that it was Vimana, even though it looks way different.
