Because I am not really familiar with the mythology, the only thing that came to my mind was lord Shiva and the prince of the Asura Gods Mahabali. I asked Beelzebub-sama
“…Is it from… lord Shiva?”
[Nope, to my surprise, it is actually from Indra — the Heavenly Emperor, Sakra. He said that he has a plan to make Hyoudou Issei-kun stronger.] […!?] Most of the members here were surprised by the report that Beelzebub-sama gave! Of course! For that God of War who wore an aloha shirt to have a proposal to me! It’s certain that the Heavenly Emperor Sakra is a part of the Hindu mythology! S-Strengthening plan? I-It sounded like he was going to drag me into something bad… I became fully alert. Rias then put her finger on her chin and said while thinking
“For the Heavenly Emperor Sakra to help the enemy…”
However, Beelzebub-sama looked pleasant. [That God of heaven looks like he is really enjoying the tournament. He even said that he would like to make this tournament a success so that one can be held next time and the time after that. And so, the Heavenly Emperor Sakra wants to hold a ceremony in a certain mythology’s territory for Hyoudou Issei-kun. The name of this land is made up of the words ‘Sea’ and ‘Breast’, the ‘Ocean of Milk’]
—Ocean of Milk!? What is that dream-filled world!? T-That is not something that was recently made, and is actually recorded in mythology!? Beelzebub-sama then continued on…
[From this point onwards, I heard that a messenger will come and guide you. Please follow that person. Well, I’m sure that the Heavenly Emperor wouldn’t do anything bad.] … Just me, going to the Ocean of Milk, huh. I looked at Ravel to check ‘Is it okay for me to go?’. “I trust Ajuka Beelzebub-sama, and would like Issei-sama to go train under the Heavenly Emperor, Sakra. I am also quite interested in the strengthening plan from a God.”
It seemed like my manager also agreed. Well, there is a limit to how much strengthening can be done including my dragonification in a short span of time. I, Ravel and everyone else also knew about this. If that’s the case, then I suppose there is no harm trying to follow the plan proposed by a God. I’ve never directly talked to him and the only thing I knew about him was the fact that he was someone who really liked wars. But, it’s also a fact that the calm Cao Cao and the first generation Sun Wukong surrendered themselves to him. If that’s so, I would decide to bet with this small possibility. “I understand. I am also quite interested in this ‘Ocean of Milk’. I’ll go there. I’ll leave the rest to you guys.”
Everyone nodded in response to my words. And, as everything had been decided, Nakiri said to everyone
“Well then, shall we go to [Belzebut]? Everyone, did you bring your mobile phones? Since the possession of a phone is a basic condition, for those of you who don’t have one, please get one immediately. For those who don’t know about phones, you can probably get one if you just ask Ajuka-san.”
…A cell phone? [Belzebut] did somehow sound familiar though. Because there were several members who were confused, Nakiri continued
“—[Belzebut] is a game that Maou Ajuka Beelzebub-san created. The place that we are going to train at, is inside that game.”
I personally was also super interested in [Belzebut], but… the place that I’m going to is the Ocean of Milk. And with this, I went to the Ocean of Milk while the others went to start their training inside that game—. “I came here to pick you up.”
—The person who was sent by Sakra to the Hyoudou Residence was Cao Cao! While being urged by Cao Cao, I went towards the underground room where the large transportation magic circle was. Cao Cao then prepared the Hindu transportation magic technique. “To think that that you would come here. You are unexpectedly pretty busy, huh.”
After I said that, Cao Cao shrugged his shoulders. “I am basically Sakra’s vanguard. If I am told to ‘do it’, then I have no choice but to do as he says.”
The Hero Faction team that was led by Cao Cao also continued to steadily gain stars in the Tournament. He still lost at times if the compatibility, and other factors were poor, but there were two Longinus Sacred Gear users in that team who had attained their Balance Breakers. Since Kantei (Guan Yu) was one of the members, their chance of winning was surely high. It was one of the veteran teams who were regarded as very likely to qualify the for the main stage. …Since the qualifiers were approaching to the final stage, even though it was Sakra’s order, for him to pick me up was… Somehow, I felt bad for him. It seemed like Cao Cao was done with the preparation and while binding the sign with both his hands, he yelled ‘Ha!’ energetically. The demonic transportation magic circle completely changed into a Hindu transportation magic circle. while causing a light vibration on the ground “Gogogogo”, a two-doored stone gate emerged from the floor! The stone gate had godly symbols engraved across the doors. Cao Cao then put both his hands on the doors and pushed them at once. Our side was flooded by the dazzling light from the other side of the opened gate. But, we didn’t know what was on the other side of the door because of the blinding light. “Well, shall we go then?”
While being urged by Cao Cao I walked towards to the door as I tried to block the light with my hand. –And, what lay ahead was a sandy beach. I could hear the satisfying sound of the rippling water ‘Sa-sa-’. However, what was in front of my eyes, wasn’t a blue sea, but a vast, milky-white sea! What lay beyond the door was a sandy beach and a milky white sea! Guessing from the information beforehand, I understood that this was the said “Ocean of Milk”! T-This is the Ocean of Milk huh~! It’s the colour of cooked rice! As if being pulled by the ocean, I ran into the beach, but all of a sudden—
“Yo—, Sekiryuutei.”
—And, someone called me from behind. When I turned back, there was an intimidating man standing there with short hair and round sunglasses, an aloha shirt, and a string of prayer beads around his neck. —It’s was Sakra! I instinctively took distance from him as I prepared for battle, but when I realised ‘Ha!’, I released my fighting stance. …Because he always seemed to emit a violent intent from his body, I unconsciously got into a fighting stance. I then greeted him for the first time. “S-Sakra…san! H-Hello.”
He looked down with amusement at the frightened me. “I didn’t think that you would come-ze. Well, since you’re here, just take it easy.”
As he said that, he snapped his fingers and two wooden chairs suddenly appeared nearby. Sakra then sat in one of those chairs. “Welcome to the Ocean of Milk. Now, please sit down.”
The God of War urged me to sit on the chair. …I sat down next to him anxiously. B-Because I had never directly talked to this God, I felt afraid, or rather didn’t know how to deal with him… After all, all we heard from Azazel-sensei was that he was someone who possessed a dangerous ideology.
