Goddess Hestia's POV
Abandoned Church
"Bell-kun..." I said defeated, Bell was in a corner of the church crying for 2 hours.
He lost a magic book that wasn't even his, and we even retraced our steps to see if we could find the book, but all in vain. The small object had vanished and was nowhere to be found. Bell wasn't lying about the book, so it was obvious that the book was real. The young Bell even mentioned that he bumped into someone on his way to the church and got a little distracted at that moment, but he couldn't remember what the person looked like, except for having a star on their forehead, something that shouldn't be hard to find, even in Orario with such a peculiar tattoo. But we can only do that tomorrow; the day was ending as the sun was setting at this moment.
*Knock* *Knock*
A knock was heard at the door and snapped me out of my thoughts. I found it strange as I walked to the door since even though I had some acquaintances and was a goddess, hardly anyone comes to visit me, especially this late.
When I opened it, I was even more surprised because there was a young man with short, disheveled blond hair and a star drawn on his left forehead, a not very common appearance here in Orario. It didn't take Hestia long to realize it was the man Bell had described! His clothes were a bit dirty, as if he were a homeless person, and the smell was not very pleasant...
"Did he find Bell's grimoire and come to return it, or..." I imagined the reason for his visit in my mind.
"Can I help you?" I asked anyway to hear the reason directly from his mouth. There was a possibility that he could be a new family member. He seemed strong, despite the fact that this man looked like a beggar, but I wouldn't deny him.
"Ah, yes! Hehehe... I bumped into the boy who came to this church some time ago and noticed he had a book of his, which I accidentally took, here." He said awkwardly as he showed the book, but I felt some half-truth in that statement. When he finished saying those words, a shadow loomed over me, and Bell, who had heard the man, stopped crying and immediately ran to the book in his hands.
He practically jumped on the newcomer and took the book, not forgetting to thank him sincerely for it quickly.
"THANK YOU, THANK YOU, THANK YOU!!" Bell shouted, bowing multiple times, and before the man could say a few words, my son ran to the couch and started reading the book as if it would disappear again at any moment.
"It was nothing, Mr. Adventurer... I guess..." He said awkwardly, looking at Bell, and when he saw Bell running to the couch and opening the book, he smiled while still looking at Bell, and his eyes shone as if he expected this kind of behavior from my son, which I found very strange...
"I am Goddess Hestia, and on behalf of my family, I would like to thank you for returning the book! May I know your name..." I wanted to know more about this young man who was a few years older than Bell, but I didn't finish my question because I heard a sound as if someone had fallen to the ground. I quickly looked behind me at Bell-kun.
When I saw him, he had fallen unconscious to the ground, and I was frightened at that moment and ran to him.
"BELL-KUN!! BELL-KUN!!" I said as I shook him and noticed that he had no injuries, just the fallen book. I picked up the book to see what he was reading, and then I was shocked when I saw a blank book.
[- GRI-GRIMOIRE!!] I quickly looked at the door and saw the man who had given Bell this grimoire, but he had already left...

Lucius POV
Somewhere in Orario
Walking through the streets, I yawned as I looked at the early evening sky.
"I'll try not to mess with this world's canon, at least not with this. Bell needs the Firebolt spell to grow, and as I acquired it without buying it from the system, it was still available for me. So, I spent my points on it before going to the church.
"I stole it from this world's canonical MC, so it was fair for me to return another grimoire, right?" I said to myself.
I headed toward the dungeon as soon as I saw the boy faint from the grimoire. As I left the slums for the city center, I realized that time had passed quickly since leaving the abandoned church, and Orario had already started its nightlife.
Most adventurers were either in bars or in the Pleasure District at this point. There were some who had their own biological families and spent their time taking care of their spouses and children as soon as they left the dungeon, but this didn't work for the vast majority of adventurers. Since adventurers had the opportunity to get rich much easier than any average profession, they preferred a promiscuous life with drinks, prostitutes, or adventurers of the opposite sex who preferred this kind of lifestyle.
I passed by some bars as I approached the dungeon entrance. I saw the famous pub where Syr or Freya had given Bell the grimoire, but I kept going without paying much attention to it. I didn't want to interact with that crowd yet, not tonight. I had no equipment with me since it had been taken from me when I left my former family. I was wearing nothing more than dirty civilian clothes.
I was met with many disgusted looks as to why a beggar was out here on the main streets instead of staying in the slums. I knew I was a very attractive man to the opposite sex in this world, according to all the standards and requirements of the female sex, but I had dirt on my face and my clothes, and a horrible smell, so I was clearly looked down upon as a beggar as I walked. I didn't care much; I needed money and knew how to get it more easily, ignoring all the looks and comments people made when they saw me. I continued on my way to my goal.
In the area, there was a large building next to Babel Tower, with a huge door for the constant flow of adventurers. I ignored the strange looks and entered directly.
Passing through the corridor to the entrance of the stairs, I was lucky that there were no guards at that moment. With my appearance, I would have spent some time answering their questions until they released me or I had to threaten them, but seeing the empty entrance was a big surprise for me, something that shouldn't happen all the time. But I took advantage of the situation.
"Hey, look at this! A suicidal guy!" one voice said as I passed through the hall and started going down.
"And why should we care? It's this guy's problem, not ours," another said.
"Tsk, the guy is clearly a beggar wanting to end his own life; dying by monsters is a terrible way to end your life," someone said.
"Are there no guards in this place? Someone stop this suicidal guy!"
"So young, he's the same age as my son
