One of the best - Hilarious and not smutty

Pretty hilarious, the MC isnt insufferable and isnt so perverted as to make the manga smutty.

The ending was a little rushed, with no real resolution. While the spinoff (a timeline where the MC never went back in time) scratches the perverted itch the question of what ever happens to the MC, and which girl does he end up with, is never answered.

Quite hilarious manga

The story presents quite funny situations. Some are so absurdly unrealistic that is precisely what makes it so hilarious. It has no argument way too deep, it's just nonsense comedy. It's absolutely not recommended for those who may feel offended by seeing children (even in drawings) in a somewhat erotic situations. If you don't mind this situation, this is the manga you want.

Unless you're one of those people, who think that cartoonish drawings of imaginary naked children in pseudosexual situations = sick pedophile shit. Then it's not. Then you shouldn't read this manga. It'll make you a pedophile, you know.

~> Just get it over with and do it. <~Also MC got=none
(Later chapters none of them fit the definition of completely innocent ¢>})Also all character actions in this story point to a warped world so ya
That's it *_* ...oh also the MC should try to understand women better ,and learn the value of a harem(while respecting who the wemon of it are and their values and feelings and motivations )
. XP

Reason for my rating and a bit of my opinion without spoilers -
[I like this because it is funny ,while they may be youths and revolves around a perverse male lead this story is funny not sick (you know exactly what I mean if you tap/click on the lolicon genre ).This story does force the nudity it's not that bad ,I say this because the characters actually are affected and impacted by what happened ,unfortunately/fortunately for the male lead.The females do remember the actions they've had with the MC and it progresses the harem and makes them act differently towards MC moving along the "plot bigrazz " what little the female characters have bigrazz (Joking).Also the characters do have some aspirations and MC does try and help (miserably ,due to erotic God's interfering XD ).So while it may be filled with select acts of intimacy the author does try to make the story a story, readable ,fun,perverse (obviously,why else is it highly popular with a lot of guys),and enjoyable .]

Anyways thanks for reading this humble commenters opinion
A P.S. and spoilers bigrazz
Sister needs to learn when to experience the pleasures of the flesh.Also defiantly if you have "Morales" (or if you were "normal" you(as the sister ) most likely interrupt the MC's...actions,but sister is essentially acts like a wing man and looks like a procreation demon. I mean she had sex in the car that your brother was in and then when kids are around you start experiencing animalistic desires(necking/getting nasty/fooling around/coitus/whoopy/coupling/fornicating/love making/bumping nasties ); this is just the me who really wants the MC to make some kind of move instead of seeing (some*_*) reandome explicite acts by side characters/sis ...she kind of progresses the story ...and in cousin included ,because if so she has the highest chance to be ravaged should our lovely mangaka proceeds to cast the dye
One last thank you if you made it to this meaning you read most of what I wrote ,so thanks.I hope you at least agreed with some of what I wrote(or thought it was funny ) but that's all upto you ,peace {ő}

Wonderful if you don't mind the loli genre

Stay away from this like the plague if you hate loli. This is not for you. If you love loli, this should be in your reading list right next to Kodomo no Jikan and [m]Ichinensei ni Nachattara[/m] .

If you are ambivalent to loli but love harems with dumb MCs, this may be for you. The story embraces his foolishness while simultaneously conveying his feelings of regret and desires to reform to readers. The fact he failed in life once already makes his continued stupidity a lot easier to swallow also.

The art is detailed and expressive. Think GTO with cleaner lines and a lot more nipples. The humor tends to skew towards cringe comedy with a lot of sex jokes/misunderstandings. This is very much a harem manga so expect the usual tropes that follow the genre.

Remember, if you hate loli, don't read this. If you hate harems, don't read this. Leave the rest of us alone.

For a Lolicon-Type manga its "technically"not a Lolicon Manga.(Kind of)

I read the first 25 chapters: Its not bad but him being a kid again removes the "Lolicon" element that this is known for. The main character is retarded as he doesn't seem to be using his "Future smarts"very well.(At least he didn't go through another annoying thing in Anime: Memory Loss. Damn it to hell I hate that, its badly overdone) If I were him I'd go for it: he can't prove to anyone that he's "25" in his position now can he? The artwork is well done and innocence is a scary thing indeed. Overall I can't recommend it only because of the target audience. Its a worth a read though.

Some peeps get freaked out over loli.. Well get over yourself already. Loli is stuffed in all sorts of manga. Dont like it?..then stop reading manga and go back to superman and spiderman. Liking loli is not the same as being a pedo. Loli is fantasy...Pedo is a crime. Those that can't distinguish the difference are the problem.

I'm not sure why people trying to rate manga when they don't like the genre or niche? What's the point? Oh, adult lolicon? let me read it. Ewww! why is it adult lolicon? seriously? Idiots

Sickening indeed

I agree with the reviews below me. This manga goes of the rail pretty fast and and the pedophilia comments are not an understatement. Especially with the art style as the (female) author writes lolicon hentai for a living after all.
I wouldn´t be surprised if online viewers will ban the manga in the future. And now is is getting an OVA!
I can smell the hate on anime sites already and would be surprised if this manga leaves Japan as i regret ever stumbling open this but i won´t be looking at it anymore. This isn´t a comedy but trash only.
Again!! and the reviewed Boku Dake ga Inai Machi are good time slip alternatives. I also reviewed the award winning Naisho no Tsubomi which is about child sexuality and all are a 8/10. Do yourself a favor and just walk away as i am only trying to help and read Vladimir Nabokov´s classic Lolita instead as it is a masterpiece. Young Animal Arashi is further magazine with zero content of quality so stick to the main version of the publication instead.

some seriously sick shit

seriously who up voted this

so much sick nasty pedophillic shit in this manga. basically a 25 year old in a 12 year olds body (due to time travel) gets off (as in cums) of making out, groping, and exchanging views of private parts with other 12 year olds.

seriously gross. plot is ridiculous, no dimension to characters, and basically for pedophiles.

if you want a time travel manga about a loser who replays his childhood boku dake ga inai machi ( is a much better manga, with a more interesting premise where he tries to remember and thwart a kidnapping and murder that happened as a child and affects his future.

if you actually like this manga get some help. and stay away from playgrounds and elementary schools
