Nifonium Dungeon, 7th floor underground.
　As soon as I encountered it, I punched Mammy in the side as hard as I could as she attacked me.
　The fully-body-bandaged monster swooped through the air and plunged headfirst into the ground, its body momentarily bending in an inverted "ku" shape. If it had been a human, it would have died for sure.

　Still not enough damage to defeat the monster, the mummy struggles to get up and approaches with a beehive of electricity all over her body.

　I intercepted it with my bare hands.
　I didn't use magic, and I didn't draw my gun.
　I fought the monster completely with my bare hands.

　Self-binding play, an even stronger binding than I'd done before.
　From my experience on the 15th floor of the tellurian floor, I fought the mummy without any tools, so that I could deal with every situation - and dungeon - as I would eventually be able to handle it.

　He dives into the pocket faster than the mammy coming at him and slams a knee into his stomach.
　He grabs the back of Mummy's collapsed head from his knee and slams it into the wall, followed by a stomping kick to the head.
　With a flowing combo, he takes down the mummy, the monster disappears, leaving the seed behind.

　I boost my abilities with the seed and look for the next monster.

　I opened up and encountered all three of them together.
　When they recognize us, I beat the first one coming towards us and grab his head and twirl it around. Mummy becomes a giant club and rips down the other two.

　They don't use magic, they don't use guns, they don't even use weapons.

　It's as if I'm back to the way I felt before Emily gave me the bamboo spear.
　That took some work, but by mid-morning I was safe and my spirit rose from a C to a B.

　...... is up, though.

Hmmm.

　I crossed my arms in the dungeon and twisted my neck.
　Today's bindings weren't bad, based on the results.
　It was a little unfamiliar to me, and I'd take the occasional counterattack, but tomorrow I'd get more used to it, and if I was careful and serious, I'd be able to do no damage.
　I can expect that to happen based on my experience so far.

　But I felt like I was missing something.

　The 15th floor of Tellurideon, the 15th floor, was different from when I was actually restricted there, both during and afterwards.
　I felt like something was missing.

The difference between being tied up and being tied down, I guess.

　I thought about it for a minute and came to that conclusion.
　When you bind yourself with your own rules, you will inevitably get a kind of indulgence, in fact, I'm still out of the gun.
　You can break your bindings if you want to, and there's no penalty for doing so.

　But the 15th floor of Tellurium, and a dungeon that doesn't allow silicone-like magic.
　The bindings are something that can never be broken.

　I guess that made a difference in the seriousness of the situation.
　And then.

'I've tied myself up in the past, but I might as well get laid in a dungeon where I'm actually restricted and get laid in the field.

　It was the opposite mindset of the adventurers of this world.
　Adventurers think about getting around consistently, while I think about overcoming difficulties now.

　It's the opposite of what I think.
　But it's better to do it.
　When the time comes, as it has in the past, you'll need strength and technique - and experience.
　And for that, you'll have to take on the challenge.

"And then there's ......

　I thought about it for a moment and returned to the mansion through the transporter gate.

'Ah, Lyota-san,'
Celeste. Just in time, I had to ask you something.

　She nodded her head curiously as she said to Celeste, who was walking in from across the hallway.

'What is it you want to ask me?'
'Celeste knew a lot about dungeons, didn't she?
Yes, in its own way.

　That's how Celeste speaks, quite a bit of humility in it.

'Is there something you want to ask me about the dungeon?'
'Yes. I'd like to hear about the dungeons and floors that are restricted to play ...... or something else.
......
'Rogue dungeons like Aulum, silicon magic bans, special tiers like the Tellurian fifteenth floor and the Nifonium sixth floor. I'd like to hear what other special dungeons like that are out there.
Do you want to elaborate?
'Yes. ...... Oh no. Just give me the name of the dungeon and the name of the hierarchy.

　I stopped halfway through and rephrased it.
　If you ask Celeste, I'm sure she'll tell you what kind of restrictions are in place.
　But there's no point in asking that, if you're going to challenge yourself in a restricted area, you'll learn to be more resourceful if you don't know anything about it.

'Okay, I get it: ...... here.'
Yeah?

　Celeste took out a folded piece of paper and handed it to me.
　It's a small, folded piece of paper. The edges are all messed up, like a receipt that's been in my wallet for a long time.

　I take it and open it.
　It had dungeons and hierarchies written on it.

"What's this?
It's on lockdown.
What is this stuff?
I was told that Lyota was training in the dungeon and I knew I would need this one day.
......

　I was surprised, I didn't think they were prepared for me.
　I looked at the paper I got again.

　The letters on the plain paper, the ink color was slightly different from the beginning to the end, the size of the letters and the thickness of the lines were slightly different.
　You can see that he wrote it first and then added a few more things from what he knew.

　In other words, he'd been preparing for a long time.
　It was heartbreaking.
　Celeste's concern for me made my heart ache.

　I grabbed Celeste's hand and looked her straight in the eye.

'Thank you!'

　I said.

I mean, you didn't do much. I just picked out a few things I know about--
But still, thank you!

　When I thanked her again, Celeste blushed.
　She smiled as if she were a little girl, smiling and looking up in depression.

'Good, ...... for being helpful.'

　Celeste looks happy.
　I stared at the notes.

　The notes with the names and hierarchy of the dungeons, the evidence of Celeste's hard work in researching them, the majority of what she added later were from dungeons other than cyclo.

　I was more and more impressed by the fact that the Family had looked into dungeons other than cyclo, which they don't usually get involved in.

'Celeste, let me thank you for something.
That's enough for now.
No,

　I interrupted her words.
　He held up the note and looked straight into her eyes.

'This note is worth as much to me as the Nihonium itself. Nihonium is a dungeon that will give me status, and this note should help me develop my technique.
......
I'd like to repay you for that: ...... and let me heal you.

　When he said that, Celeste was surprised for a moment, and then returned to her normal expression.
　She smiled calmly, to her usual, mature Celeste.

'Don't worry about it. I'm not one of them.
But then...
All right, I'll think about it. I'll think about it. Since you're such a big fan of it, we should think about it.
Oh, think about it!

　I'll do anything.
　I feel like I have to do anything and tell Celeste how much I appreciate her.
　If she wants me to think it over carefully, then of course I'll wait.

"I'll be in the dungeon, then.
Yeah, have a good day.

　Celeste sent me off and I used the transporter room again to get to the dungeon.

　　　　　☆

　The hallway of the mansion after Ryota was gone.
　Celeste turned herself around and walked out and went back to her room.
　It was still high in the day, at this time of day when all his friends were in the dungeon, and he returned to his room.

　He entered his room and closed the door behind him, the moment.

'Uh-huh, uh-huh.'

　Celeste grinned.
　She jumped on the biggest stuffed animal in her room, the one that looked exactly like Ryochin, and held it in her arms, rubbing her cheek.

'Yay!　Mmmmmm, that was helpful, Lyota-san.

　Despite her usual composure, Celeste was like a little girl, revealing her joy.
　She held the stuffed animal in her arms and slumped on the bed.

''Ufufu, Kyahoy!''

　She tossed the stuffed animal and caught it again, rubbing her cheek.
　Celeste was so happy, and she was innocently happy because she was in her room.
　She held the Ryota-like Norichin plush toy (handmade) in her arms and was much happier.

''Ryota-san ...... ufufu ......''

　Despite the lack of magical storms, the joy of the day kept me from working.
