Reincarnation in DxD with wishes

After we were given our names, everyone talked amongst themselves for a while and then parted ways. Now that I've been reborn, I can play with my demonic energy.

So far, I haven't entered the Mind Palace yet, and I will not enter until I grow up, I've decided to train in space-time manipulation instead, at least until the age of 5.

Oh, being a baby is so boring. You can't even move properly, and when Rias cries next to me, being a baby doesn't help at all. The only good thing about being a baby is drinking milk and being able to pee whenever I want.

You might want to know why I chose this world. Well, because I love the background story of DxD. Come on, but this world is also a world where mythical creatures are real, which is pretty epic.

Now, as for how I'm going to train demonic energy, I'll shape the energy into a form and then create increasingly complex patterns with that energy. After checking my surroundings, I'm struggling with demonic energy to make a 30 cm string and slowly make it spin in the room.

1 year later...

Finally, I turned 1 year old, I can proudly say that I've made quite some progress in energy manipulation.

I can control 10 1-meter strings with each of my fingers. After celebrating my birthday, I'm taken back to my room. To be honest, I don't see much of my brother, his wife, and my father.

They're all very busy, and I don't blame them, after all, Sirzech Maou and my father have a lot of work. At least I can spend some time with my mom, and that's good for me because I had quite a trust issue in my previous world, and it continues even in this world. Thank you to my family and all my friends who betrayed me.

My reserves increase as I use them too, so this year, I've paid a lot of attention to demonic energy, and yes, I have low ultimate-class reserves. I should slowly develop my space-time manipulation, and I'm trying not to arouse suspicion like in some fan fiction. I mean, who thinks it's normal for a 1-year-old child to go to a library or train himself?

Anyway, after the birthday party is over, I'm taken to my room, and after confirming that no one is around, I try to feel the space around me, and I can say it's a very strange feeling. Watching everything around me and thinking that I can intervene... But even that tires me out.

I'm not used to it, and I'm not going to try to manipulate time for the feeling, because I'm not that crazy.

Imagine accidentally being thrown back a million years, space is risky, but I'm trying to control it somehow. I'm slowly getting used to the feeling of merging with space, but the more I struggle, the more I adapt.

After getting tired, I work on developing demonic energy manipulation, and I create a cup with my energy. After exhausting all my energy, I cry for milk, which is quite embarrassing. After drinking the milk, I lie down.

2 years later...

Finally, I'm 3 years old, and my relationship with my family is good. I try to behave like a normal child.

I can say that during this time, my space manipulation has significantly improved. Since then, my reserves have reached peak ultimate class, and I can say that they have increased quite a bit. I can easily create heptagons with demonic energy manipulation, and this will be useful as a barrier.

After confirming that no one is around, I enter my Mind Palace after all this time. Now I'm looking for Occlumency.

After finding it, I started applying the instructions slowly, and it's going quite well. Now I can place the information I've learned in my mind wherever I want. For example, memories, emotions, and everything I've learned so far are there and thus will replace this photographic memory.
