3 chapter 3

After all that, it's time to work on time manipulation. I call a servant for this and ask him to bring me an apple; I want it to be flawless. After he leaves, I bite the apple and place it on my desk. I try to revert the apple to its previous unbitten state using my mind, and it's quite exhausting. Yes, I finally did it; the apple returned to its previous state. Despite the effort, I think it was worth it.

I'm going to focus a lot on time manipulation this year so that I can use the technique I want. I will develop as much as I can before my family trains me, and I will learn a couple of spells in my mind palace. I plan to learn gravity magic and the demonic energy version of the clone jutsu instead of chakra.

While I'm thinking about this, Rias enters my room, and I must admit, loli Rias is quite cute and has been spoiled since childhood to become the bratty character we see in anime.

And for some reason, she always wants to come to my room and play with me. I always refuse; I don't have time for such things, especially with EXE and knowing Trixhia's existence. I want to be prepared for such things as much as possible.

Theo: "Rias, how much longer do I have to refuse you to leave me alone?"

Rias: "Oni-chan, my mom's busy, and there's no one else to play with me."

Theo: "Please, leave me alone; I'm busy."

Rias: "I HATE YOU!"

Theo: "{I can't waste time on the path to the strongest, so I'm sorry, Rias, you'll find someone else to spoil you.}"

I learned the clone jutsu in 6 days; now my progress will be faster. I will do workouts when I turn 5 years old, my body is already strong, and the abundance of energy over time allows my body to adapt accordingly. Thank you, Demon Physiology. Anyway, my body has weaknesses, such as holy energy, and I have a crazy idea to fix this.

Yes, I will try to copy HxH Netero's training. For 2 years, I'll punch 10,000 times a day and express my gratitude to ROB between each punch, and over time, my body will show resistance.

And since I can't do much else, I want to practice some martial arts or assassination techniques. I enter my mind palace and find the assassination techniques of the Zoldyck family. I think they'll be pretty powerful if learned properly. When searching for martial arts, I came across the Bleach Shinigami Hakudo techniques and decided to learn them. I make 3 clones; one practices Hakudo, the other assassination technique, and the last one practices time manipulation while my original version practices space manipulation.

As time went on, I got used to these two techniques, and I understand them, but the Zoldyck family's assassination techniques were a bit challenging, but at least I can feel progress. Thanks to the essence, I have no limits, and I feel my abilities are increasing. Learning things is easier now.

As I have free time during training, I think about things as much as I can; I don't like to be idle. And when the main character of this world comes to mind, I smile because a normal person can gain powers to defeat gods in just 6 months, which is quite bizarre, and I think about if I have to change the canon. Then I realized that the canon had already changed by the time I arrived, so I'll behave more freely.

I think about Riser next; yes, he could have a harem and be a scumbag, but we're demons, and it seems meaningless why Rias hates him so much. Given the time she had, she didn't train, and she relied too much on her power of destruction, which was useless.

Sometimes I think Rias's sins might be laziness because she's very lazy sometimes.

After all, every demon has sins, and I think mine is wrath. Sometimes I get angry too quickly, and I don't want to show it to my family.

Riser has pride and lust sins also, he has political reasons to marry Rias. A political marriage might be possible for me because I member of a noble demon family, and I don't care as long as they don't stand in my way to power.
