The number of books in the Great Library was as good as it could be, and I was able to gather quite a bit of information about the Necropolis.

　After Flora's departure, although not enough, I was able to acquire useful knowledge about the structure of the ruins and the nature of the enemy.

　The Dead City Necropolis is believed to extend to at least twenty layers underground.
　At least, that was because there were only adventurers who had reached the twenty layers underground.

　Only one person had reached the 20th layer was the legendary hero Pericles half a century ago.

　It was sung that there was no brave man better than him later or earlier, and he had actually accomplished such feats as defeating the guardians of the abandoned city of Realm all by himself.

　His abilities were so far apart from the other adventurers of the time. So it didn't matter how good a saint or sage he was, it only slowed him down.

　So he had always been a solitary person, and he was alone in attacking the ruins.
　Pericles was truly the most powerful adventurer in history.
　Even so, he had failed to capture the Necropolis.

　Pericles was severely wounded on the 20th layer, and although he succeeded in escaping to the surface with his life, he died of his wounds a few days later.

　One day I took the journal out of a closed stack bookcase.
　It was written by Pericles.

　I muttered, "Someone has been reading this book lately.

'Someone has been reading this book lately.

How do you know?

　I answered Filia's question.

'This book is the only one with so little dust. All the other books around me just open it and a storm of dust rolls up.

　Perhaps Flora had seen it.
　Maybe Creon and the others have already confirmed it.

　I open the diary and run my eyes over the last date line.
　It's the day that Pericles died in his room after failing to capture Necropolis.

'Something evil and frightening and huge and shiny in the shape of a man came upon me. I have been betrayed by the gods.

　That's what the diary said.

　Filia nodded her head.

'What does this mean?'

'Come on. 'An evil and frightening giant' could be the Demon King that Flora was talking about. But when it comes to the second half of the story, I'm not quite sure what you mean.

　What is a luminous person in human form?
　For example, if they are the kind of spirits, they may take on the appearance of a human form.

　This is because spirits are a collection of magical power, and they imitate the appearance of the original owner of the magical power.
　But an adventurer as big as Pericles would have been able to recognize a spirit, and if he did, he would write that in his diary.

　Without coming to any conclusions, we had no choice but to examine the structure of the middle layer before the twenty layers, the enemy races, and so on.

　Many adventurers other than Pericles have attempted to capture the Necropolis, but in the end, the second layer of the Necropolis was only completely liberated and the rest was still a den of demons.

　That's enough to find out about the Necropolis for today.
　There's something more important than that.

　It's why Filia's magic power has gone out of control.
　Unless we do something about this problem, we're going to do it all over again, and we won't be able to let Filia grow forever.

　But it was more difficult to look into this problem.
　After all, the descendants of the Demon King were rare, and there was almost no literature on them.
　Even if there were, they were all superstitions and fairy tales.

'Nothing........can be found.

　Filia says, sounding a little unwell.
　Hmm.

　I'm in trouble.
　I don't want to let Filia down too much, but I can't find a solution.

　As Filia and I are sighing in the corner of the reading section, we hear footsteps.

　Who could it be?
　I was a little alarmed.
　If Flora's story was true, it wouldn't be surprising if someone from the Salvation Knights came to kidnap Filia.

　But the one who appeared from behind the bookshelf was definitely on my side.

'I've been looking for you, Solon. Why don't you turn to me?

　The woman puffed out her cheeks and said.

　She's a slender beauty, brushing back her red hair and staring at me with her crimson eyes.
　She is wearing the loose robe of a magic school master, but even that is dyed crimson.

　The very two names of 'crimson' are fitting.

''Lucy-sensei!　Why are you here!

　I raised my voice, and Filia also looked at me with a surprising look in her eyes.

　The person who was there was the Imperial School of Magic professor and my teacher, the 'Crimson Lucy' herself.
　Lucy spun the quill in her hand and looked at me with zit eyes.

'I heard from the maid at Solon's mansion. She said you were in this library.'

Oh I see....

　It was just as well.
　Lucy might be able to help me with Filia's magical outbursts.

　But I should have known that Lucy was in a very bad mood.
　Lucy quickly pulled out her wand and pointed it straight at me.

'Solon is there anything you want to say to me?'

I don't know what to say... It's as if I'm going to die.

'Solon lives in a house with Phylicia and Sophia and her maid, right?　I bought a mansion all the way down here.

Yes ... yes, sir?

I heard you're sleeping in the same room as three girls.

'No, yes, but I wouldn't say it's anything to be ashamed of...'

'Heh. Even though you're hugging Filia after her bath and flirting with Sophia in her underwear?

Who told you that?

The maid's girl. Clarice, was it?

　I put my head in my hands.
　I could picture Clarice happily flipping out to Lucy and saying, "This happened to me!" in my head.
　And I'm sure she's exaggerating.

''Solon........''

　Filia interrupted in a whisper.
　I expected her to help me, but she didn't.

'I wonder what you mean by Sofia-san and I were flirting in our underwear?　I've never heard of it before.

　Filia smiles at me.
　Not good.
　Filia has misunderstood me.

　I simply happened to run into Sophia and Clarice while they were changing and I was trying to calm them down because I was about to scream.

　But I don't think they'd believe me if I said that.

　Lucy looks me up and down with her crimson eyes and says in a whisper.

''I heard that Solon's ... mansion was attacked by Arte and the others, and was almost killed by Princess Iris's Highness.

'Yes. But we managed to do both.

'I was so worried when I heard that. Why didn't you turn to me for help?

I haven't had time to talk to the doctor about it.

　It was so urgent for both of them that they didn't have time to go from my mansion on the outskirts of the city to the magic school to ask for help.

'Hmm. Then I should just stay close by.

"Huh?

I'll be living in Solon's house. It's settled.

What ... what?

'I've been worried about Sophia since she came back to your side. It's not just the Knights, the Church and the government are trying to take advantage of Sophia. I didn't want to put both Solon and Filia in harm's way because of the people who are after Sophia.

　Perhaps that was the reason why Lucy was the only one with a gloomy look on her face when the July Party attack was settled.
　Moreover, Lucy seemed to have more specific things to worry about.

''Anyway, it would be more convenient to protect Filia and the others if I was there too, right?

Well, yes.

Besides, if you leave Solon and these kids together, there's no telling what kind of antics they might do.

　Filia chuckled.

'I think Lucy is jealous of us!

I didn't!

　Lucy's face turned bright red, and then she cleared her throat in a very cute way.
　Then she points her wand at me again.

"Come on, Solon. Will you allow me to live in Solon's mansion too?

Well what's that wand for?

I'm not threatening you.

You mean he's threatening me, right?

'Here's the deal. Instead, I can tell you what Solon and the others want to know. I mean, I can teach them how to properly control their magic.

　I opened my eyes.
　Lucy knew, after all, that she knew.
　That the Demon King's descendants would let their magic run amok, and how to control it.

''What do we do, Solon?''

　I sighed.
　Lucy, on the other hand, was looking at me a little uneasily.

　I said slowly.

'I wouldn't make a deal like that,'

　Lucy looked very hurt.
　You don't have to look at me like that.

'After all ... you don't want to live with me?

'I didn't say that. You don't have to make a deal like that, I wouldn't reject Dr. Lucy.

What?

'It would be very reassuring if the teacher would stay in my house. Because Miss Lucy is my teacher.

　I smiled and held out my right hand.
　Lucy gently squeezed my hand back and her cheeks tinted with embarrassment.

'Right. You're my apprentice, aren't you?'
