One moderately suggestive page every 10+ chapters don't make a manga ecchi.
Fanservice is supposed to be the main dish.

Japan doesn't produce nearly enough manga about couples that just and simply enjoy having sex. Without any unnecessary drama or complication.

What?
That's true...
I wonder what other manga i was checking at that moment. ¯\\_(ツ)_/¯`

So tame it doesn't even deserve the tag "ecchi" (seriously, is enraging how misused is this tag. Ecchi doesn't mean "there is an attractive woman in this manga" or "a girl is wearing a short skirt").
I would not even compare these two.

The family is still suspicious of her. But her age match and thanks to her knowledge from the old woman's stone she is able to diguise herself as Alicia.

Finally we are seeing her again. For those who have forgotten it, she appeared in chapter 3. She found a fragment of the stone that was supposed to transfer the old woman personality into Alicia.

At least he is allowed to release his load. Many ecchi protagonist can't even do that.

But this trash was fun and interesting...

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.
