Ryuzaki POV
After regaining his consciousness the first thing our MC saw was darkness boundless darkness that will make people lose their mind but he was reincarnated so he was safe from the darkness.
Immediately after seeing the darkness he understood that he was in his mother's womb although he says nother he wouldn't recognize this mother as his mother because the only parents of him were the parents in the previous world where he was born.
Now after thinking about his parents he decide it would be a good time to see his skills description
The god said you can't see them until you are in the new but technically he was in the new world as he was inside his mother's womb and her mother was in the new world aka DxD so naturally he was also in the new world so he opened the skills description.

After seeing the description Ryuzaki was so incredibly happy that he would have started jumping up and down if he had a body right now.
As he has arsenal cube he can choose the same 18 weapons in both of them and just like that he dosent even need to train to increase his proficiency he only needs combat experience to become a genius in armed combat.
Ryuzaki has a idea to gain large amounts of combat experience in a small amount of time he just needs to wait a little bit after being born.
Morphing now this skill was a skill on which Ryuzaki had a quite a lot of ideas on what could it effects could be he was not 100% sure on any of the ideas.There's also the side effect of timeline he needs to find a way so that he dosent get to affected by the side effect.
MORPHING
This skill let's the user change his appearance into the 18 year old version of himself nobody will be able to tell what the age of the user is by any scanning method. It only requires the user to initiate it after that it will only turn off after the user wants it or the user ran out of mana.
Seeing this skill Ryuzaki wanted to slap his past self thinking that he had called this skill paltry.
This skill alone negated the side effect of the timeline and also allowing to helping him start some of his plans which required to be at least 10 years and older to come to frutition way earlier than expected.
Now the only obstacle he faced was to how the hell is he supposed to spend the remaining 9 months in the womb he cannot increase his mana reserves as if his mother is not related to the supernatural she might have some troubles.
So the only thing he could do here was wait and not cause any troubles that might lead to his potential death after 9 months.
2 months later
It's been 2 months since he decided to not cause troubles but simply lying in the darkness without doing anything proved to be extremely boring.
After lots of consideration he decided he will plan on the things he will do after 3 years of his birth. The first is what any reincarnator will do increase his mana reserves by emptying his reserve everyday. Next is the plan to learn touki if possible like sairaorg if he trains it will be possible to achieve it in 5-6 years. Making the idea he has to increase his combat experience possible.
5 months later
After making a lot of training,fighting and rewinding his memory of dxd he is finally ready for the world. He has made plan on how to deal with all the possible antagonists of the DxD series as he dosent want them to run away cause trouble again. He has also made plans about how will he change the cannon and affect the characters though those plans require him to know when will he be born. There are endless possibilities because he dosent know his race
or if he will be born the cannon starts or after so all the plans may be useless depending upon the time he is born.
1 month later
After running all the possible timelines he could be born in and the race he may be born as he decided it is foolish to think about that as long as he has enough strength he can do something according to his plans. Now the most important thing is about is harem now dont judge me we are in DxD it is the LAW to have a harem. Also as this is a AU will the historical characters have their fate personalities or other do they even exist thinking about this stuff he started thinking something what if with is coding knowledge he made something like the brave saints or evil pieces.
He can create the class cards and if fate characters exist he can use the cards on them thinking about how the class cards will be coded he forgets about the timeline and AU setting problems as he is a coding maniac. He forgets his surroundings if he is seriously coding.
1 month later
Finally the moment is here now he will finally see the new world the time line and his race. The last month he made the prototype of the class cards in his mind now only testing and making a little changes are required although he might need some high quality materials to make them.
He starts hearing voices and grunting noises like push a little more , it is about to be done like that.
Finally he is in the hands of the doctor and he got slapped by the doctor as he was too busy about his surroundings and forgot to cry. So he started to cry.
After seeing that he dosent recognize the parents he figured that he was a human and apparently his parents have decide to name him Leonhart Esperio.
He was getting sleepy as even if he is a reincarnator his body is that of a child.
Next time he opened he eyes he heard a lot of children crying and making noises and after seeing a nun looking after the children and no signs of his parents he figured out that his parents left him in a orphanage.
The only thought going in his mind was
WHAT THE FUCK.
