I'm glad to be back! :D Look forward to it~

Thanks for the warm welcome back! ^ - ^ (Also, I'm really happy to hear that you enjoy my story! :D)

First and foremost, congratulations on claiming the prestigious tile of 'First'! May you lord it over your non-First peers for the week to come~ That aside, thank you so much for stopping by, for the continued support, as well as for the kind words :) I'm very happy to see you here, as usual :D

Very good question! :D Most of them think that it is because he has a Divine Falna, a Falna made using the blood of a primordial deity. They then make up lots of theories in their own heads about how that could possibly be the case, many of them coming to similar conclusions involving a scheme of Ouranos or others. That's pretty much the gist of it. As for Dionysus, he pretty much falls into this category.

It's because a lot of suspicions that have been building up already, regarding the Blades in general... So Isaac decided to only act against those that directly go against him. Of course, letting them go will also enable him to send false intel via their channels if necessary, because he could always fool them. There are even more reasons than that, but I'd have to check many tens of pages of my notes again to find the rest. I hope that these ones will suffice already xD

Oh, they could. The worst of it is the mental aspect - not many people can deal with solitary confinement in complete darkness. Of course, there are some that can easily deal with it, but the vast majority of the population doesn't fall into that category. Therefore, his mind affecting his body to a noticeable degree is to be expected, so that why he chose to appear this way.

Very good question. I'll have to go into a bit of detail here, so I hope you won't mind! Every Hunter-series Development Ability can only be unlocked at its respective Level, and only by killing a specific amount of same-Level monsters in a specific amount of time. The requirements increase as the Level increases as well, so nobody ever got any Hunter-series Development Ability outside of the Level 2 one before Isaac arrived. As for why nobody ever got the Level 1 one, it's because they were too weak ^^' When close to leveling up to Level 3, many Level 2's try to get 'Hunter', because this one is well known. Ais kind of rushed past that stage back then, and ever since that point, nobody thought that there were any other Hunter-series Development Abilities, so... Once someone has unlocked one of them, they can go and grind up the numbers as much as necessary at any Level, but the unlock requirements are quite stringent. Ais is currently planning to gain a Hunter-series Development Ability at her present Level, because she kind of regrets not getting one when she was Level 6... or before then. But eh, hindsight is 20/20. I hope I didn't miss/forget anything. Have a great day! o/

Good question! She is supposed to have wings. I also described Sirens as such during their initial appearance. However, as someone else pointed out a long time ago, I made a slight mistake when comparing Harpies to Sirens... because Sirens don't actually have any hands. I honestly have no clue why I wrote that back then, and I even missed it during the proofreading process... It's one of the two minor mistakes that I'm aware of that I haven't gotten around to fixing yet. It's been on my to do list for so long... let me get to it right after replying to all the comments from the past week, then! Sorry for my rambling! Your comment reminded me of something I had to do, so thank you for that! :D Have a great day~ o/

But they are connected to Isaac, which is why they were noticed and were expected to have excellent potential as well. The being that noticed Isaac is quite impressive, so this isn't really unusual for them.

I can't blame you for thinking about her like that. She'd personally also quite annoy me on some occasions.

More than 50 of them actually descend. It's quite the crowd. As for how many there are in total? Well, far more than even that.

To be fair, there is still quite some time between this point in the story and when it'll actually happen, and at that time, it won't be considered a secret anymore. I used the word "quickly" here because, technically speaking, only a few weeks will have passed when this happens... which isn't a rather quick development (and we're still not there in the story currently, at chapter 185... ahem, anyway).

They are indeed, but if properly handled and made out of sufficiently good materials (+ via excellent craftsmanship), they can last faaar longer. Especially if proper maintenance is involved.

And thank you so much for stopping by, for your continued support, as well as for still enjoying my story! :) Ais... is just built different. Quite literally. And she was forced to endure to the point that even enduring lost its meaning, so I guess anyone could make it this far if they just couldn't die, huh? I do feel horrible for having to make her go through that, though...

"And actually, now that I think about it, those good news might also be bad news. Aw shucks, how could I mess up like that~?"

Double this chapter's number, then you'll have a decently good estimation of when she'll properly appear in the story. I can't give you a better estimate than that, because I only just recently heavily underestimated the amount of chapters it'll take me to write a certain arc, so.... OTL

It's not the route that I chose to take, but it's a very interesting speculation anyway. Maybe in OG DanMachi, it's actually the case!

Your speculation amuses me. That's all I'll say. You're welcome~
