The manga is generic, cliche and sometimes cringe worthy. The concept of Chunibyou is taken way too far. I think the main character is perfectly fine as he is. He doesn't need to "grow up" and everybody is much too critical of him. He is heavily lectured and critiqued for being too nice, naive, arrogant, conceited etc. The problem is he has faced danger many times and is already quite aware but everyone treats him like a child. The 'daydreamer' attitude is heavily exaggerated and I don't even think it's a problem but I guess everyone must bash on the mc and this is the main focus of the story so far. He doesn't have a single goal in the world and every chapter is aimless.
The plot drags, comedy is not even funny, romance is practically non existent and mc is the type to refuse good women literally offering themselves to him. He's willing to sleep with a random prostitute he never met but unwilling to sleep other individuals (one of whom actually 'life energy' to live). If he won't accept a cute girl he has affection for and clearly lusts after who also loves him who the heck will he accept? He seems determined to remain a virgin/single for life but didn't have any problem trying to sleep with random unknown prostitute that has no background. Even worse he works so hard for his waifu he doesn't even seem to care about. Why even bother helping her and treating her in a way she will misunderstand if you're just going to ignore her advances forever? I am annoyed by this MC's lack of emotional and/or physical attachment to anyone or anything. He tries to sneak out to sleep with a random prostitute while also rejecting honest women he has mutual bonds with that are more than willing.
Also too many flying judo kicks with lame names he makes up on the spot. Mc just wants to copy fighting he saw in anime.
I'll gloss over his succubus unbirth in ch1 where we immediately learn he inherits power but not blood from his 'mother'. That's kind of cheating to only get power despite still remaining physiologically human. Author couldn't decide to make him human or succubus so I guess gave mc all the benefits with none of the drawbacks so he could have overpowered plot armor. I can only say I am disappointed.
It is hinted that there is some sort of significance about him being left in the forest in Ch1 but after 40ch the story is still dragging and hasn't bothered explaining.
To sum everything up... Every single chapter just drags, MC is beta male with typical "Nice Guy" concept taken way too far, he doesn't have to will to romance or sleep with anybody, he's OP because why not, cliche story is cliche, there is no clear story so far. It seems the manga will just meander chapter by chapter aimlessly until the author decides what he actually wants to do with the story.

This last paragraph is a semi-spoiler/analysis and can be skipped. I left this because it took some time to backwards calculate this nonsense so I left it for the end. There seems to be a flaw in the time line of unbirths and it brings several concerns. The below reasoning is based on the assumption that there were few or no twins, multi births, maternity period is 1 second not 9 months and the woman didn't have multiple husbands and/or children concurrently based on her personality.
The problem with the "26 other children" the mother had is that succubus apparently started having children 150 years ago because that was the reason she quit her adventuring. Therefore MC is 16 and so she had been having children for 134 years up until MC's "unbirth". Problem is MC was a special case for being extremely OP for his age and he was about 16 when she thought he was strong enough to survive on his own. Logically speaking her other children should probably be like 18 or 20 at least if they are not OP like MC. Therefore the second to last child born (the 26th) was probably at least around 20 years old to be gone when the suc mother found our MC. Problem is that means she had children from 150 years ago until 20 (26th child) + 16 (mc) years ago. This means that she had given birth 26 times from 150 years ago until 36 years ago so in other words 26 births in 114 years. That equals one child every 4.38 years on average. The problem is her life energy needs are met by being a "mother" so she should logically be giving birth every 15-20 years or so or maybe 12? Since when MC was around 12-14 she started wanting to have sex with him. Still this either means that at any given time she had been raising at least 3-4 children at a time. For example 0 yrs old 4.4 years old 8.8 years old 13.2 years old 17.6 years old so on. Based on the manga I can't even see that as possible or ever happening. It seems almost all of the "children" of hers are different races and it would be weird if the fathers of these children every 4.38 years continued to leave her knowing she needs continuous "fulfillment" so she fends for herself by finding new partners but also weird if she just continues to cast the fathers away or gets a new person to cheat with about every 4.38 years or so. Even more so the fact that 26 babies just happen to be abandoned in a dangerous forest that people don't even go to in the first place let alone bring babies. Makes no sense. No matter which way you think of it, having fathers that abandon the suc mother or that the suc mother abandons seems weird. But also not having fathers and having such an unlikely baby abandoned 26 times in a forest nobody even knows about/enters much if at all within 114 years of time is beyond unlikely. No way 26 babies managed to find their way to her in a distant A+ class forest within 114 years time and why she would have babies at a rate of one per 4.38 years on average when she can last at least 12 years from "motherly love substitution" makes no sense. I find too many things about this concept of 26 children to be illogical and make no sense and she doesn't seem like the type of person who could continuously and responsibly raise multiple children for over a century straight with how naive and irresponsible she is yet too caring to have cast her various children away. I find the thought of her raising on average 3+ children at any given time preposterous yet also the idea of only raising one at a time as that would take at least 400-500 years if she did. It's only suppose to be 134 years for 26 children or 150 years for 27 children. Looking at how the 27th children took at least 16 years then 26 children before theoretically would be 416 years if they were raised individually one at a time and let go of parenting early because they happened to be as OP as our MC (stated that our MC is an extreme case of OP so this should not be possible). Again in best case scenario mother had a child about every 4.38 years on average which is VERY EXTREMELY UNLIKELY just from the feeling I get from the manga. No matter how you spin it, none of this concept of 26 children makes sense nor how said children are also very old/have long life spans because why not.
