chapter 4

1 year later...

Finally, I'm 4 years old, and I can say I've progressed quite a bit, especially in hakudo, space-time manipulation, and assassination techniques. My energy reserves haven't increased this year; instead, I'm making my energy more intense and higher quality, which takes quite some time, but when I use my magic, both power and quality will increase.

The reason for Hakudo's development to this extent is due to practicing shadowboxing with other anime characters, and my shadowboxing has reached a level where even if shadows strike, I genuinely feel the damage. It's not lethal, but it hurts. I've also learned the gravity spell, which will be quite important for my training a year from now.

Now that space-time manipulation has reached a certain level, the anticipated moment has arrived, and I've decided to develop Limitless. After all, it could be quite overpowered, and if I use it correctly, it could be very useful.

So, when I'm about to fight someone, having such a technique will give me an advantage over them, and it's important not to be arrogant. After all, arrogance could lead to my downfall; I need to be careful.

Alright, let's begin now, I'm currently searching for the Limitless technique in my mind palace. This version has been adapted to the DxD magic system and does not require six eyes for passive use. I'm reading it in the most detailed way possible, and achieving an advanced level of space-time is necessary to do this.

This technique manipulates the concepts of time and space. In practice, the Infinity Technique creates a kind of energy barrier that protects against physical obstacles and even enemy techniques; and it doesn't require cursed energy for me. This will allow me to easily perceive and neutralize the attacks of my enemies.

Yes, I'm carefully reading and trying to apply the explanation. Initially, I'm struggling, but my training is paying off, and although I can't maintain it passively 24/7 yet, I'll get there eventually.

Now that I've mastered the technique, I can relax a bit. After all, I've progressed quite a bit this year, and suddenly, someone enters my room while I'm lying down.

Venelana: "Theo, what are you doing here all alone? You're not even spending time with your mother. Don't tell me you don't love your mother anymore?"

Theo: "I'm tired, Mom, and no, I love you, Mom. I just don't feel like playing."

Venelana: "Lately, you don't leave your room, you only come out for meals. What are you hiding from your mother?"

Theo: "I'm not hiding anything; I just don't like leaving my room. (If I act a bit like a hikikomori, maybe they'll leave me alone.)"

Venelana: "Okay then, keep sitting in your room like this, and play with your sister Rias occasionally."

Theo: "(Instead of playing with Rias, I prefer to torture myself, or maybe I'll build resistance by following the Zoldyck techniques.) Okay, Mom, I'll play later, maybe."

Then my mom left me alone and went outside.

Damn, I have to play with Rias, anyway.

The next day, when I woke up, Rias came into my room and said we needed to play, and I agreed. After that, we started playing hide and seek. I started searching first, and it was really difficult to find her. When it was her turn to count, I started hiding using my assassination techniques, making it nearly impossible for a 4-year-old kid like her to see me. So she searched for me until evening, and when she couldn't find me, she started crying. I came out and told her if she was going to cry, we shouldn't play anymore, and then she snitched on me to my mom. I was scolded for an hour.

And Rias called me a scumbag; at that moment, my wrath almost took over.

Luckily, I'm not cruel enough to beat up a 4-year-old, otherwise, I'd be a monster.

Now that I've been undisturbed in my room, I think I can focus on training, which will be quite beneficial for me.

Anyway, since I'm only 4 years old, I need to prepare for next year, and I'll work on mastering Limitless until I can passively apply it on 24/7.
