Wait I don't understand. Volume 2, chapter 12: The girl is asked what's her level. She answer that she is level 100 with stats capped at 255. How come now she is level 72 ? Maybe wrong translation and they were talking about HIS level and stats ?
You assume that is is the same, for what we know she may have stocked 20-30 of them in there, just in case: durability of a marble column may not be the highest, especially when used as a blunt weapon
The cool part about Aqua and Eris is that those two are trying their hardest to avoid any kind of training, and yet they pulled out such a troublesome (albeit flawed) barrier
Eris' "intuition" makes her spew things that are oddly relevant to the topic at hand, event if she and people around her don't have any idea of what she is talking about (but the reader does, which is what makes it funny, imo)
It was like: you slip and start falling, open your mouth in surprise, you put your hands forward to avoid getting hurt and one falls down on the biggest surface close by (her breast), accidentally fall with your mouth exactly on her nipple, astonished, start gasping for air causing something...
Page 9: "Fix this mess before Bael-sama finds out!"
Page 16, Bael: "Well if it isn't our aether. Where have you been hiding this whole time"
So Bael know that she's been missing, and he probably knows that without her they have no power.... so what should he not find out ?
I can see the two idiots of this chapter fighting one each other to the brink of death over a single stone, for the MC to arrive and say "wut? I have a bag full of those".
He just came back after 100 years in another world... how did he pay the restaurant ? Kept cash in his pocket for all that time ? Credit card with very long expiration date ? Ran away without paying ?
