Solving the crest worms problem.

"Hi, are you okay? You are not hurt, are you?" I asked the kid who was getting bullied.

His eyes were not visible, they were covered by his rough hair. Even his clothes were covered in dust. Seems like she fell down while trying to escape those three.

"I-I am not hurt... but, you got hit by him..! Are you... Fine..?" Oh, her voice is much softer than I expected. So, she is a girl... I was assuming her to be a boy with how rough and curly her hair looked.

"Don't worry about it, I'm fine. It doesn't look like you are hurt. What's your name?" 

"Ah..! My name is... Tachibana Mikari..!" She replied with slight excitement.

Hmm, Mikari tachibana... I feel like I have heard this name somewhere... Since she is a named character, she must have some significance in this World. But weirdly enough, I don't remember any such character in fate UBW, or my dress-up darling...

I should keep an eye on her... She might be a variable like me.

"So, Tachibana Mikari-san, I am Tohsaka Izanagi. You don't need to be worried about those guys anymore. They won't bully you." I reassured her with a smile.

"Umm, T-Thank you, p-please just call me Mikari, Izanagi-san." She nodded her head and replied.

"Sure, Mikari-chan. Would you like me accompany you to your house?" 

"Mm... Mikari-chan feels a bit embarrassing..." She muttered to herself, it was inaudible to me.

"N-No. I can go by myself. Thank you for your help..!" She thanked me and bowed her head.

"Hmm, go back safely then Mikari-chan. Oh! Here, take this." Before bidding her goodbye, I handed one of the sandwiches to her. She seemed quite flustered when I handed it to her, but she accepted it.

"IZANAGI-SAN! Can we meet again after a week? In this same playground?" Mikari-chan said after running a bit far away.

"Hmm. Sure!" I just nodded and accepted her proposal. A week is a bit too specific, I wonder what she's gonna do in a week.

After she rushed away, I started walking back to my house. 

Hmm, now that I notice it, it seems like this city is not much populated. Even though I walking through a main Street in the middle of the day, there are not many people to be found. Most of the houses are empty. It's a very... Empty city.

I'll look into in later. For now, I should buy something else to eat. I gave away my sandwich to Mikari-chan, now I gotta buy something else. 

I went back to the shop to buy something else to eat. After looking for a while, I found some cookies. That's fortunate for me because cookies are the second best thing I like after shortcakes.

As for why I like cookies so much... It's because,

Cookies are good.

...

Well, finally I am back to my house. Since I got something to eat, now it's time to focus on cleaning the house. 

This totally abandoned house needs to be made good enough for me to live in.

But the question is, how? 

I can easily turn this house into something better if I use my authorities, but using them somehow feels like cheating. Unless it is absolutely required, I wouldn't want to use those overpowered abilities. I should first try to complete the simulation with talents given in this simulation. Ofcourse, nothing's stopping me from using them. I can use them anytime I want.

Well, <God of Eros (Black)> is my only useful talent in world. Rest are mostly passive...

I wonder, if there's any Erotic stuff with magic that could clean house?

Ah, right! I can use simple purify magic instead. I'm pretty sure many nun hentai have that magic. But then there's another problem. This body doesn't have any mana right now, so even if I know how to use a magic, I can't use it.

"Sigh, it won't work then... I was really hoping I would just say "Purify!" and—"

Suddenly I felt myself losing strength. All of the sudden a bright light enveloped the mansion.

As the light subsided, the mansion was back to brand new. 

"How exactly was I able to use magic without mana... Ah, I understand."

Since I was simulating in this world without using <Afterlife Prologue (Red)>, I was currently living in my original body. I haven't been born in this world, instead my body was transmigrated here and I took the identity of a created character. 

That's why, my current body actually belongs to the world "In another world with my smartphone". That's why I possess mana. 

Still, I shouldn't have been able to use mana from a different world to perform spell of some another world. But, that was taken care of by <Rulebreaker (Red)>. That's how I was able to use powers of different worlds.

Hmm, that's great news for me.

Now that "cleaning the house" is complete, I have to focus on magecraft. Even if I can use magic of another world, it doesn't mean, I shouldn't learn magic of this world. Just by using a simple spell as "purify", almost all my mana was drained. I might have to train hard.

"Raphael, is your analysis complete?" 

[Yes, the analysis is complete. The crest worms and magecraft of this world has been analyzed 100%.]

"That's great. Tell me the solution to crest worms first."

[Crest worms are good for your body in expanding your mana circuits and increasing your mana capacity quickly, but they feed on your mana and force you to acquire mana from opposite sex, or by artificial methods. There are two simple methods for solving this problem. First, I can remove the crest worms from your body. Second, I can construct a skill suitable for mana regeneration.]

"Then, proceed with second option."

[I understand. I will immediately begin synthesising the skill <Infinite Magicule Regeneration>.]

"Heh, that sounds great. But, are mana and Magicule same?"

[Mana and Magicule are fundamentally same energies. Magicule is constructing unit of mana. All types of energies are just different formation of Magicules. Magicules are formed by charged information particles that are the final basic unit of every existence.]

"Hmm, I feel like I am knowing something I should have waited atleast a hundred chapters for... Anyways, start the skill synthesis."

[Yes, starting skill synthesis...]
