yes!! they are delicate!!

Author-san since you decided to catch all the waifus I have an idea, how about you make Rei learn the technique of Mu the second tsuchikage? Mū has the ability to divide into several bodies, being more than a simple Bunshinjutsu, since Mū's mind and power are divided, this ability would allow him to be with several of his girls at the same time and they would not have to take turns, in the Small harens there is no need, but in huge ones that get out of control with 10 or more girls I think a technique like this is necessary, especially with how "energetic" they are.

It would be better if he put an "analysis" seal on Kaguya so that it monitors each reaction when he uses his powers and thus acquire more precise data that he will only have to collect and study calmly

what if you make his ultimate abilities take on personality and then give them a body, for example seal lord uzumaki is reborn as Karin (yeah i like karin) and heka that protection ability is reborn as sakura (i mean since we're in that why not) and of course there is also Isis, or you can just go for Hinata has already been flirting with her in previous chapters.

Author-san a suggestion, once you release Kaguya from the moon you should turn Black Zetsu into his artificial Bijuu, normally in other fics I really hate him because he is a nuisance but in this fic as kaguya is on the side of the MC he is an ally and I think he deserves it for all the effort he put in those 1000 years since it was created, honestly if I were in his situation where all my effort was useless I would have a severe existential crisis that would possibly lead to suicide that's why I think I know he deserves it.

author-san I personally like auxiliary chapters as long as they are POV, so I recommend that if you are going to do this in the future that it be a POV of someone who knows the MC to make it more interesting, in this arc you could do it like a POV of anko or three of naruto, sasuke and hinata about how their lives changed and including a little summary about their abilities and it wouldn't take you more than four chapters and that's if you intentionally wanted to make it longer.

Sakura?

Kuroto also has that technique, so couldn't he revive Shinichi's girlfriend like that? after all a potion was used to prevent the body from rotting

I think that first you should get a quirk that allows you to store energy or absorb energy such as electrical or calorific energy or some other type of energy to solve your problem of eating and use your quirk more frequently

Author-san I understand that you are busy but could you at least post chapters on Sundays from now on to replace this week's chapters? Not that I want to pressure you since I know you are busy but I really like your fanfic so at least think about it please

Lisanna shouldn't be already dead because cats have already arrived in that world?

Harem +1 I recommend Momo and Reiko Although I think Reiko would be easier because she is in class 1-B that the MC wants to enter

+1

Reiko

Momo

By the way my recommendations are Momo and Reiko

I think it is possible to develop a small harem, you have already since himiko cannot keep up with her in bed, you can use this to make himiko make the proposal first but on the condition that she agrees or chooses it, but I recommend that you first make a special chapter that tells us about himiko's reasons and his concerns so that he doesn't feel forced.

Note: his ability "Transcribe" can evolve to Devour because as you have said, transcribe cannot copy racial skills (such as poisonous spit because it does not have poisonous glands) and I suppose that by itself it will not be able to copy the zanpakuto either but with devour and analysis it would be possible .
