Being called out by his sister, Hida Kizuna visited the Strategic Defense School Ataraxia. He met with the girl manipulating the magic conducting armour (Zeros), Chidorifuchi Aine. All of sudden, in front of his eyes, Aine was removing her clothes. “Don’t look, you pervert!” “No, it was your fault right!?” To the unfortunately sharp tongued Aine, Kizuna couldn’t help but be confused. However, there, a critical mission’s communication arrived. And its contents――to massage Aine’s breasts!? In fact, ecchi acts from Kizuna have the power to power up the girls. With that power the future of the fight with another world was at stake!!

This story feels very familiar: Mysterious aliens have attacked the Earth. The only way to fight them is to use mysterious magical equipment. Only girls can use this gear. Expect main character, of course. It does not end with just that. MC's mother is the one who developed the gear, and his sister is a commander at the battle school. Sounds any familiar? Fanservice is explained by that MC can recharge and powerup girls by doing erot*c things with them. You would expect normal, healthly male to be happy that... more>> he can save the world by doing erot*c things with beautiful girls, but no. He is a typical JP loser MC without backbone or balls. He refuses to cooperate for silly reasons while humanity is doing badly. He screams like a little girl when a woman makes a move on him. Even if he is terrified of women, he should do his duty for humanity, but no. There are some good moments of comedy, but don't bother with this if you have read too many JP novels already. <<less

I have no one else but to blame myself for reading this blasphemy. I got into this novel after reading the reviews who were praising this novel like the 2nd coming of jesus "That the novel later becomes Hentai and MC doesn't remain an idiot", but you would have to wait for 9 freaking volumes to finally get to the "decent" part of the series. After tolerating this atrocious novel for so long, you are just simply burned out and don't give a damn about it anymore.

-Just like any other... more>> Harem story, you have your typical beta arse Japanese protagonist who is weak, spineless and dense af with 2-3 abusive and cursing female characters who shits all over protagonist for no reasons where as MC acts like a complete panzy and does remotely nothing to trying to do anything to protect his little bit of self-esteem, but I can tolerate that it is still within my limit, but oho boy, here comes the MOFO VOLUME 4. Protagonist's harem gets captured while they were infiltrating another Country, then you finally feel the tension, the stakes are getting higher, but for no goddamn freaking reason, our dear author decides it would be better to force them into becoming singing idols, f*ckING SINGING IDOLS which goes on for 3 volumes, what makes it worse is that our protagonist is still fighting for his living and having close death-life battles with enemies in the background while the gals are enjoying their idol career and completely forgetting they are actually prisoners. You can imagine my frustration, as somewhere along the way this review has turned into a rant. Why in the unholy name of god the writer thought it would be a good idea to put that right in the middle of a serious battle arc? Making cute girls idol, sure make them, but for heck sakes do it in your spin-offs or make a separate filler arc. Call me dense, I don't know how Japan's idol industry works, but surely the popularity can't be this much worse, right RIGHT?

-After the long arc that was finally over which lasted for 4 volumes (thankgod). We are introduced to God level beings, no let me correct that suicidal and depressing god beings because they are immortal and utterly bored of their misery life. You simply know just how it goes from here, our MC is gonna cure their heart or make their life better so that they won't feel suicidal anymore and with that, I think this was the final nail in the coffin for me. I will leave myself out, I don't give a damn if it has hentai or MC becomes less dense in future volumes, none of that matters anymore. I regret reading this novel, I wish I could get my dead brain cells back! Save yourself from reading this novel, don't listen to the reviewers who have given it 4 or 5 stars. It only deserves 2 for the softprono! <<less

Summary of the novel: While this novel has an average IS plot.... its actual high-quality hentai, because the MC does not remain an idiot for long.
For those of you watching the anime is HxH AA to hot for anime? Like closer hentai than To Love Ru or High School DXD ever got? The answer is yes. Both the anime and novel are straight up hentai. The hentai action is only in later novels, but trust us... the R-18 is there. The MC is not an idiot.

I just love this one. The beggining let you think that the MC is spineless but it isnt the case. He will grow confident as the serie advence as well as the lvl of ecchi, ... more>>

at start boob grabbing to where I am fellatio and hand job :D)

The plot is quite good for a harem, except for

Kizuna's Mother, sorry I just hate her way of thinking

For the girls, well they arent 1D. They have things they want to do and have problems to resolve and our MC will do his best t help them. I really like the fights (since our MC WILL fight as he will become stronger)

Finally, I am giving 5 stars for me, but for other it would be more like 3.5/4 since harem LN arent really liked (well for me its a must)

P.S. My fav girl is Aine (personally for me she is the main heroine) and Himekawa (for her shyness) :P <<less

Not bad... not bad at all. The only problem of this novel are the fight scenes but the MC and the girl get amazing power-up and combine their power-armors. The H-scenes are really good tbh. Its no straight hentai but you have the feeling of it. In my honest opinion the MC should just take out his d*ck and shove it in their a$$es, but he mostly harasses them. But if you are looking for some echhi stuff then this is a good read. There is plot but its not... more>> that good atm. I hope it gets good later on. <<less

I love this one. The writing style in raw is good too. It gets better after u reach volume 5.

MC is not dense either and there are tons of R-18 scene but no s*x at the moment, there are some part that is "indirect" sex...


Like using the heart hybrid armor core, and the shape of the core turned into dildo sharing the sense of our MC penis, and inserting the dildo shaped core (Weird writing this one) into the females body through their vagina.

It is quite familiar to IS but with more fanservice and somewhat character development. If you like Testament of Sister Devil or Magika no Kenshi then you would enjoy it.

Reading other reviews, I agree with that he was acting 'beta' but I see it as a believable reaction. Not even a healthy male would immediately accept the responsibility of saving the world and their mind would be hampered by normal morals to assault any females or easily accepting any of the sexual assaults.

Instead of crazy scientist that is the... more>> sister of MC childhood friend, the scientist is his Mother thus eliminating the need to favor the childhood friend. This make things more personal with the MC.
Each girl has their own personality and shares of problem which MC helped to somewhat solve;
MC do no fight harem member number 2 at the beginning but saved her while changing her outlooks on others. This helped smooth things up for that girl in later volumes.
MC helped disperse the feeling of unwanted of harem member number 1 as they shared a history and allow her to be more social.
MC also helped to pull harem member number 3 out of her vengeance and her despair and give her new objective in her life.

Cliche of only mentioned Male with a worth to use a Gear as other Males have lower energy and mentioned only once, if I remember correctly, that there is a male side of school.
In my opinion, which can be said to many other LN, the harem keep on growing even extending to other world's female characters with each use of his special Gear and the magic 'aphrodisiac' ability. (But it can't be helped because its a ecchi genre) <<less

Honestly, this novel is very good... I loved it too much. If you've been looking for Ecchi in this novel, it's here that you will find a lot of it (much that gets saturated there by volume 8 or 9), the way things unfold is very much to my liking and worth reading. My favorite character is definitely MC's mother, watch her and see for yourself.

... more>>

Ahh, a warning... do not wait for the act of penetration itself until volume 13, it just happens before the final fight... after they prove the real sex, it will happen a lot and who monopolizes the MC is actually his sister.

For those with any familiarity with JP LN/WN of the shounen variety, this is more or less the same plot, I like it when done well and dump on it when it is not. From the rating you can infer my stance.

Now for the main question. Are the H scenes good?

Seen better but I've also seen worse, all in all a 5/10. It is passable but dragged down by the characters and writing, an ok read if you just want to turn your brain off. Though, I must give credit... more>> to the illustrator, there were many good pictures.

But if you care about complex characters/ unexpected turns/ character dev/ any semblence of tension/ a proper non-pu*sy MC. Better go read Magika no Kenshin/ Sevens/ Mushoku no Tensei.

How should I put it in non-spoiler word. The writing is bare minimum, characters are 1D even though their awesome pictures are 5D, any character change is totally artificial only meant to move the plot forward.

Plot/ logic is terrible.



That is just some of the many logical faults in the story. I get that you want a highschool story. But tone, setting and characters must match, exceptions work mainly for comedy.

ie. They have 20+ floats and only 1 that we can see is for war. Brah, if it's the other way around idm because people need recreation but when the majority are relaxing on their boat not making an obvious effort to get back their families, it destroys the tone you are trying to go for. Sorry, I said non-spoiler, but don't worry all those parts are right in the beginning of vol 1. It's a very minor spoiler. Combining both character and Plot give a failing 3/10. <<less
