Case in point, in the chapter I just read (v1c1 part 6), he decided to tell everyone that he was a reincarnator. This would be a very interesting decision, and a logical one, especially with his desire for an interesting and self-fulfilling life. However when he tells his parents, they... well, they still consider this 45 year old inside their child exactly the same.

What?

It just killed the narrative for me and made the previous poor characterization even more obvious.

I have nothing against harems when are handled correctly like World finest assassin, but this harem was dumb, main heroine permits him having more women since she will out live him and cant have children, ok that's an ok reason, but him adding an old tiger lady out of the blue makes no sense why the main heroine would permit and encourage it, since she will also not be able to give him children and she will die first than him, makes no sense, the childhood friends while qualify in the baby making department, its just disgusting, he supposedly see them like daughters and then he just decided to randomly add them as brides ok they were adults by then have no problem but there is no romantic development afterwards other than some forced kisses and hugs we don't see any development, they are just plain extras that do their thing while fighting and in the background they barely interact with MC, it only distract from main heroine to shine, and also we don't even get to see if he had kids or not really dumb seems like Author had no clue how to handle the harem and we got nothing good out of it.

When he confesses to his family that he is from another world and there was no negative reaction and they just accept it non clamantly right three I should have stop reading since its a given character development is going to be bad.

I feel like most of the plot was dedicated to him being the god of alcohol and there was no real main plot, takes ages for him to find the child he is supposed to guide, then after it was found it literally does nothing for more than 1 year and takes many chapters till something happens (there was never real guiding from him) and then suddenly he is not supposed to help that child because the gods say so, then a big fight happens that kills almost all the people he cares for including all his harem, he throws a tantrum with the gods it works and everyone comes back to life :/ I could not believe it, then there is no development from there, next thing we get after the big and deadly fight is that he is dying on his bed from old age and main heroine was the only one there before he dies like wtf, we don't know what happens to the cast, did he had children? did he mourned the death of the other harem extras? probably he outlived the tiger lady but what about the other childhood friends at least Sharon had also magic ability so she should have lived long enough but we get nothing the harem was handled terrible if the author already committed to have an harem at least don't do this kind of crap to try and redeem that the most import one was the main heroine, then when you think it cant get worst, we get teleported back to japan and MC picks up from where it left at the age of 45, gets a ring on the door and somehow main heroine is there the end I almost lost it on how bad it was handled... suddenly I had flashback when I was a kid and finish Mario bros 2 for the NES that ending was equally terrible

He eventually can make custom spells seemingly at the drop of a hat but doesn't really do anything ground-breaking or even modify them to be tactical. It's pretty much: shoot spell - does damage the end. For humans being hit seems to be basically instant death and for monsters it either works and kills them or does nothing.

Child is found after around 200 chapters but even when it's found the chapters just march on ignoring the fact that the fated child is found and just talking about dwarves and alcohol like usual. As I've said I've read up to 236 and so there have been over 30 chapters after the child is found and none of them even have a mention of the kid. Why? Isn't that supposed to be the main plot? There are 529 chapters out as of me writing this review so I guess there is still time but it really saps my motivation to keep reading if the main plot isn't even slightly addressed in almost 40 chapters. End Rant

He rejects (in a very weak way) his two childhood friends because he is an over 40 year old man and they are around 12 but then it is just sort of glossed over and assumed that he will add them to the harem when they are old enough which is honestly quite disgusting. Meanwhile he is having continued s*xual relations with two other older women.
