I think "gal tensei" did a better job with this concept.

The anime kind of was, and mostly cause it was overly memed.

Make a manga about girls with overly massive tiddies, and then don't show anything...
This is the very definition of useless.

Standard "i want this thing to disappear" kind of villain. Quite a boring and uninteresting guy.

Is not pre-determined.
It was said clearly that whoever kill her have prediction abilities too. So if she take a different action she get killed in a different place. And if she escape then the assassin will start targeting all the other mages.
This is not "destiny". This is planned.

Yeah, but usually they always use the knowledge from another world for their purposes. Or at least like "gal tensei" give a distinctive trait to their character. Or to give a moral standard to the protag like the MILF harem isekai were the protagonist like MILFs cause he was a middle aged man in his world, and so every woman under 30 look like a child to him.
Raoul never mention anything at all about his previous life. It doesn't give him any trait, any knowledge. Is like it was put there only and exclusively to make this manga be classified as isekai... if it is one.

This could be an explanation.
But i think there is another way to read this. Raoul referring it as "this was before i was reincarnated for my revenge".
Seriously, the isekai detail is so irrelevant and forgettable it make me wonder what is the point of it at all.

Right?
I can see it mention a reincarnation... despite apparently having no memory, no knowledge, or any desire to return to the other world...
It's really easy to forget that detail. So much that even the other magareader sites i use and myanimelist don't tag it as isekai.
I'm starting to think it could be some mistranslation.

Wait... isekai?
I noticed this is tagged isekai in this site, but i don't remember where is ever revealed that Raoul come from another world.

This 20 years thing confuses me. In the previous chapter looked like Raoul was saying it was only an illusion and it was not actually 20 years.

Technically it's Atsuo Ueda.
But he really do a great job at drawing like Mashima. To the point is even difficult to discern it.

I like these sisters dedication.
When they are set to perform their duty nothing stop them. Like her sister that when confirming the identity of the hero she kept going despite being naked.
Also, this mangaka is an hell of an artist. He can rival Kentaro Yabuki.

Another entire chapter wasted on something that could have been done in two pages...

You cannot fix perfection.

So... Aria is able to play heroine.
Well, i guess it would have been a pain in the ass to leave these guys alive. But she really looked like she was disgusted by the whole affair and decided they had to be punished.
Apparently she didn't succumb to complete cinicism. Injustice and cruelty can piss her off.

Surprised from the back twice, and the second by a mob monster that should not be trouble to him anymore...
Suspicious.

The title is a pun on "attack number 1" a old and very popular volleyball manga. And the origin of many popular tropes in sport manga even today.

I knew only one place that updated the chapters to the uncensored version when available. But sadly got hit by a lawsuit.
You can still manage to find scans of the official english release if your google is powerful enough. Still... if the uploaders or translators don't want to update to the uncensored version i would prefer to wait and have the uncensored chapter instead.

Dude... don't read comments if you don't want "spoilers".
Of course we discuss what happened in this manga until now. But anyway, from your comment i can tell that you dropped from chapter 106 or before that. So you should check the chapters from that point and before.

I stopped feeling death flags after the resurrection of Bell.
If we didn't get a relevant death at that point, there is very few chances to see one now.
