The ending is quite pleasant too. I will read it again from the beginning in the future I think. To enjoy the story in full without any break.
I have read two things the last week :
Hard Boiled Cop and Dolphin : it's from the Beelzebub's author and if you have liked Beelzebub, you will not be disappointed by it and his humour. It's short (47 chapters) as the serie has been axed, the last fifteen chapters are very fast paced because the author clearly wants to close all the loose ends. And he does a honest job to it. If you need something fresh, a bit funny and not too long, it's worth the time.
Isekai bishoujo juniku ojisan to : I begin to read it because I was bored, and when I discover it was a isekai (didn't pay attention to the title at this time, the cover is enough to choose for me), I was thinking to drop it after few chapters as usual, and... It didn't happen ???
The cause is that the manga has a lot of humour but it doesn't forget to speak about the psychological issues of the main characters quite regularly and has put an interesting dynamic between them by playing with gender. An interesting point too, it's that I usually drop isekai because the main character is always too much powered, too smart, too everything. As we have two main characters here with different capacities, it gives a feeling that things are more balanced and that not everything is solved by one perfect human. The fact that they are both old (32 years old) give more possibilities about their past which is a plus. The other characters have their own agenda too, and the ennemies are not dumb and try to act a bit smart against these heroes. It's not a lot, but at least, there are more in fights than just "me strong, me special abilities, me beat you" as big boss fights are usually used to reveal the psychology and the complex of the heroes and to make them work on them and move forward mentally. It doesn't happen often though, on the 150 chapters, the manga has two big cases which happened. But it's nice to have big fights been mostly resolved because the heroes are dealing with their psychological problems, and not just because the hero can bruteforce the ennemy.
To be honest, the thing is dumb most of the time. But I will say it's good dumbassery. It's a bit borderline sometimes, but very far away from the usual creepy things you can find in a bunch of mangas, so, it's mostly okay ( I think but my brain has been rotten by too many mangas now, not sure that I have a good eye for borderline things).
A bunch of chapters are ten pages short too (because the author has some health issues sometimes), so, even if it has more than 150 chapters to read, it's less long to read that it seems to be.
So yeah, this thing has totally my seal of approval for now and I hope it will continue this way for a long time (and it seems they still have a bunch of things to tell btw).
