he can turn any imaginable concept into reality, he need to restrain somebody? He will use "restrain" magic. He need to find somebody? He will use "find xxx" magic. He need to move quickly? He will use "teleport/fly" magic. Something broken? He will use "repair" magic. He need to fight a legendary being that can destroy a country? He will use "dimension cutter" magic with an umbrella/stage prop. Even in the end of the series he used "time stop" magic to defeat all his enemies...
First maid heroine Chiffone only appearing like three times in the whole series, first being her introduction and the rest are joke chapters. Second appereance during the MC's school vacation he take the elf heroine back to his mansion, she lashes out that some bug is attaching to the MC. The third and final appearance is at the end of the series, she's confronting the ikemen tutor and accuse him as gay and shotacon and that he is the most probable winner of the harem since she realizes that the MC only regards her as a maid and the elf heroine is in the BFF promise of a friendzone.
The second elf heroine Sephys is having one chapter form her point of view in her introduction phase, describing how she's having a crush at the first sight with the MC, then no progress whatsoever and near the end of the series the MC put her in the friendzone (after that she's not even mentioned at all, not even on the final chapter.)
Meanwhile we got a seme do-S black haired ikemen tutor who the author jokingly refer to him as "Princess" in her digest chapters. He's "interested" with the MC and the MC interacts with him the most. The maid heroine regards him as shotacon and gay, and she states that he have the highest chance in the MC's harem.
Then we got a legendary male white dragon summon with a very fitting and creative name "Shiro" that's pretty much useless since the MC is a god, right after his first dragon form introduction he magically transform into human form, ikemen. Then the dragon form is forgotten that he never appears at all in dragon form. He got no important role in the main story and only act as butt joke.
Lastly we have an adult ikemen leader of the most elite secret service group "ninja" yeah the name of the group is ninja and they wear ninja-ish uniform. Even though he is supposed to be the most elite personel in the whole kingdom, he easily got kidnapped (similar to the princess tutor's case) and the 8 year MC have to save this sorry excuse of a secret service agent. Well, it's basically BLish damsel in distress with a shota saving an ikemen instead, apparently the author likes this so she used this plot twice in her story arc.
And then we meet a knight fall in love with the MC when he used genderbending magic to transform into a loli, he chooses to defect from his job to aid the MC and leave his hometown so he can be with the MC. Then he found out that the MC is actually a shota. Then he's in dillema whether to keep liking the MC or not with the inclination of being shotacon is probably alright. Poor knight. MC turned him into shotacon...
There's a couple of MC's male friend in the school, one got a name with extremely terrible Japanese pun... They're not important though.
After a few moment the heroine introduced, the outcast/bullied part being thrown out of the window, he turned into riajuu instead of being hated by the country as stated in the synopsis and story becomes highschool battle romcom complete with it's tournament arc... The main heroine is pretty much shoved into the MC and the affection point being MAXed abruptly. And then later the main heroine being shelved and another girl seemingly taking her role. Mind you that not even the author knows why it turned that way...
the game heroine is an otherworlder for god sake, the same as the MC! And the MC is seemingly quite informed about gaming culture at that! He even have seen the game heroine's notes about the game capturing strategy. Why can't he consider confronting the game heroine and reveal that he's also an otherworlder?? That way he can get her cooperation to avoid harm for his master and heroine! The MC can strike a deal that the game heroine can freely capture her targets as she please but just don't harm the heroine, he can even offer helping her!
Or even better he can actually have a discussion with her and tell her that this world is not the world of game. It's normal if other people can't comprehend Maria's actions, but the MC is fully aware of it yet he's avoiding the source of the trouble.
Or he can just bang her like the other girls to get her favor, it's in line with his work ethic, but somehow he won't do it with her.
He left his family and then completely forgetting them, not even a shred of phrase is spent to bother mentioning them again. Instead everything in his mind is about how he's fawning over random boy who saved her from random tugs, and surprise surprise the whole shyness tick is abandoned for lovey dovey acts. All the first part of the story is flushed out that you'll think it's a different series...
Kazura's naivety's hurting the story later, he doesn't want to help the country preparing for war with two country that wanted to attack Kazura's country. Even though he know very well that if the country is being attacked they will definitely lose and all his precious acquintances will be either dead or enslaved. He's "Nope I will only provide you with food and daily necessities, I won't help with military at all." Because he doesn't want to dirty his own hands by inventing ways to produce war tools, Valletta decided to prepare for the war alone behind the scenes without Kazura knowing.
He's so reluctant taking action to protect the country that he have to call his father for advice, and as expected the father wisely told him to do the thing he needs to do so he won't regret it later. It seems it's a clue so he will finally take a countermeasure acts for the war, I'm so happy that it seems he will move the plot again, yet after that he still won't do anything as if he immediately forgot his father's advice.
Later the MC become somewhat pathetically useless compared to Valleta, basically she does all the hard work (designing new tools with the help Kazura's book, negotiate and managing craftsmen, mining steel, smithing weapons etc) while Kazura remains oblivious in his naive world with his beloved compost and windmill. He can't even perceive malicious intent at all that even a potential antagonist almost snatched Valleta from him and he only thinks of "Maybe it's fine to give her to him for the sake of her future... I think he's a nice guy." Not until Valleta cried desperately because she doesn't want to be given to that guy Kazura realized that it's stupid to hand Valleta over to the other guy. Yet later he disclose all important secret plans to this potential antagonist/bertrayer... the raws stuck at this point that even some Japanese reader also fed up with the current Kazura...
