Yu-long took me to his territory, it was beautiful surrounded by forests, lakes snow covered mountains and between all of the beautiful scenery was a large Shinto shrine. After landing there he changed into his human form. He was now 6 feet 5 inches tall well built bald Buddhist monk and surprisingly handsome and if not wearing any monk attire any woman would fall for him.

Yu-long where are we? I've never seen this place anywhere in Kyoto, said Issei. Well first of all call me Yu and not with my full name like that geezer monkey and for where are we, we're currently in a part of the Hindu mythology heaven given to me as my territory by Indra-sama, said Yu. Hey wouldn't Indra be mad that you brought me here since he actually dislikes me, said Ise. You have got a big mouth as usual with no brains, Sekiryuutei. After hearing this I realized Lord Indra was actually standing behind me with some of his vanguards consisting of Cao Cao, George and Leonardo. Don't worry Sekiryuutei, since you are not a threat to the world I would not kill you, said Indra. Sekiryuutei long time no see, I came here to wish you good luck for your training. Train hard and reach the peak of your powers and then we will fight each other to see who is the best and for your information Vali is training like hell so if you want to beat him word hard. Chao after saying this Indra and his vanguards vanished.

Looks like Indra-sama likes you. So now go and take any room as you like and after you freshen up we will start your training. After freshening up when I got to the training grounds I saw another monk there covered in scars beside Yu, so I asked him who was he. Oh don't worry about him, he is one of Indra's vanguards but he hates him so he lives and stays with me. He is the battle god "Ashura" that Indra defeated and when time will come he will also teach you. Ise before I teach you how to use senjutsu in draconic style I have one condition you have to agree to, said Yu. What is the condition, Yu? Issei questioned. Issei I think you know that you are currently half humanoid dragon and half devil and if the King Piece would be taken out from you would be a dragon. And if you train hard enough you would become emperor class dragon and eventually a "Dragon King".

[Wait, wait so you are telling us that you are a contender to become dragon king asked Saji. No Saji, I'm a Dragon king and my title is "Infinite Apocalyptic Poison dragon". How can this be true? None of the leaders of each faction was told about the ceremony. Even when Eldrax was chosen as a dragon king every leader of all factions, every dragon king and both the heavenly dragons were present for the ceremony so where your ceremony occurred and why we were not told, questioned Siaraog. Hey all of you don't get angry and for your information my ceremony is next week and it will be held in my territory and currently Apophis, Eldrax and Tannin-ossan are preparing for the ceremony. But Issei your territory was taken away in the underworld so where is your new territory, asked Akeno. Have you all heard about purgatory? Hearing this everyone was shocked beyond belief. Issei-niisama tell me that you are joking, said Millicas. No Millicas Red, Ophius and Trihexa gave it to me as a present for resolving everything between them. But Issei our late god sealed those creatures there that would be a problematic for the world if left free, said Irina. Yeah Irina I know but those three massacred every being in there and renovated it for dragons before giving it to me. Now all the evil dragons reside there and it is managed by Crom Cruach and Apophis. Roughly 100,000 evil dragons reside there. So technically I've an army of evil dragons. Ise-senpai didn't they went extinct, asked Gasper. No Gasper they were living in dimensional gap but their condition was terrible. We found them on a large piece of rock floating in the dimensional gap feeding on just 100 scales of Red that he shed. For thousands of years they were just living on it and this gives us an estimate of Red's power. Now they don't matter anyone in their territory as long as the individual is strong according to their standards and those they don't seem worthy is killed. Sounds like a bizarre and horrifying place. Issei-san how can you agree to making of such a place, asked Asia. I didn't Asia all the evil dragons we saved begged me of this rule and all the evil dragons in my peerage fulfill their request. But I had a condition that the one that kills the other will bury them with honor and everyone accepted. Now whenever any of us visit there all the evil dragons welcome in a grand fashion. There my home is not as big as this one but it's very beautiful and was made by the evil dragons. If you will see it you will think it is covered by marbles but in reality it is actually covered by shed and polished dragon scale. So what about this castle, asked Rias. Actually Skithblathnir is the familiar of me, kids, and the great three combined. So it is actually our home and not only mine.]

So where were we right, I was told that I was a dragon so it would be a disgrace for a dragon to weild a dragon slayer so I had to stop using it, forever. So do you accept it or not, asked Yu. Even if didn't liked it I had to accept the conditions imposed on me. So Ise let us get started. First of all tell me what you learned under that monkey while learning touki. I learned we all have life energy and the stronger the individual physically stronger the life energy but this is why every senjutsu user must have a strong mind since if the mind is broken you just become an empty shell of power with no self conscious. You are right and I know you will be able to learn the senjutsu to its core no matter what the old monkey says. So what you will do is that you will is fight with Ashura everyday till you learn to identify every little energy signature from your surroundings and this way you will learn every possible martial arts in the existing the world. Okay Yu I understand.

So for one and a half year I fought Ashura just to survive. The way I would describe him is that he is strong, skilled, knows every form of martial arts, can handle any weapon as it was a part of his own weapon with god's strength. He taught me how to be a dignified fighter but to win you will have to go to any lengths even using underhand tricks. Since he used many underhanded tricks so I learned how to feel energy signature of every individual in space around me. I was so pissed off by that so I went to Yu too confront him.

[Issei kicked the door to enter Yu's office]

Hey Yu I thought you were going to teach me using senjutsu but all I've been doing is fighting my ass off with Ashura without my balance breaker only using touki just to stay alive. Maybe the old monkey was right that you only want to play. So tell me are you going to teach me senjutsu or not? Ise questioned. Now, now Ise-kun don't be such a blockhead. Remember I told you that you are going to learn about senjutsu the dragon way, well you have reached halfway to your goal, said Yu. I don't understand what you are saying, said Ise while being confused. Well Ise do you know why dragons don't use senjutsu even though it is a formidable technique while they can sense others energy? To Yu's question Issei could only say no. You see there are many ways one can fight but mainly classified into three categories. First there are those who only fight with their body for example- Siaraog Bael, Grendal, etc. Secondly there are people who fight with magic like Ajuka, Mephitopheles, etc. And lastly those who fight with auras but this technique is largely used by dragons. You see mostly everyone but dragons are synchronized with the first two ways of fighting but dragons are mostly constricted toward using their aura. Aura based techniques are the most powerful types of attack but largely drains an individual. This is one of the reasons why dragons take such pride in themselves as they posses such huge amount of aura. An aura is made up of an individual physical and mental composition. This is the reason why everyone's aura is different and can constantly change. Dragons only like to use aura while the others like to use physical and mental prowess. Mostly senjutsu is used by Yokai but it is extreamly difficult for normal individuals since they do not posses the natural ability to se life energy and till the time they learn it they are comfortable with their own method and discard the thought of learning senjutsu.

But how is knowing all this can help me learn senjutsu? Questioned Ise. You see with fighting Ashura you learned two of the most important things. First you learned every type of martial arts at the highest possible level and secondly now you can feel the life energy of others consistently while being attacked. You learned to manipulate your own life energy by meditation and to make your life energy stronger you trained very hard to increase it's offensive and defensive capabilities. Since now you can fell every individual life energy and even under the condition of heavy stress I'll teach you to manipulate it. It usually takes 25-30 years of meditation to feel others life energy for someone who is not a Yokai but fighting continuously with extreamly tough opponents while being handicapped to learn to feel every energy signature in the surrounding is the dragonic way to learn senjutsu.

Remember controlling others KI works on the same principal but in the opposite way, so if you want to use powerful moves more your stamina would be consumed and vice-versa. So for the next six months I was taught how to manipulate others life energy or KI. Ise your training is completed now what will you do since you still have 7 years left for your training. I don't know Yu, I am confused. Once I was training under Tanin-ossan, Draig asked ossan to teach me how to use his aura while I was still human so I was thinking I should learn to use Draig's aura but ossan cannot teach me since I am banned to meet anyone from the underworld for 25 years. That is some good idea but since he cannot teach you there is one who can. Out of us six dragon kings (including Eldrax) one of the best aura user of all time. Only she can teach you how to use yours and Draig's aura but you would have to prove yourself worthy. Yu don't tell me it's Tiamant-sama. Yeah the strongest dragon king till day.

Now everything aside take this pendent on which a charm is made up of my scale and the other is made of Tanin's scale. And the empty slots would be for charms you receive from Midgardsomer and the last one from Tiamant only if you survive her test to prove yourself worthy. Ise I'm sending you to Midgardsomer and don't worry I had everything sort out for you. He will teach you everything about dragon magic and if you pass his training you will receive his scale as a charm for your pendant. Now go Issei get stronger and become one of most powerful entities in the world my student.

[A green dragon gate appeared below Issei which shined brilliantly the faded away after Issei was teleported]
