The following doujin review is my subjective point of view of Kokutou Nikke (Akutensoushin)’s doujins. After reading their doujins for 5 years, I found that their doujins are always very useful to me. I fapped to their works A LOT.
Their doujins are always filled with huge pregnant belly, hardcore plots, giving births, and the occasional hilarity. I recommended these doujins to those who like this kind of elements.
According to 真・悪転奏進 the official website of Akutensoushin, the doujins of this group was scripted by Shirasaki Kare(白崎カル) and drawn by Kokutou Nikke (黒糖ニッケ)
In addition, Shirasaki Kare has also published some doujins in collaboration with Kotaru (瑚樽) from Sirotaruto (紙場こた) , but personally, I think Kotaru’s drawing skills are not as good as Kokutou Nikke.
In their early days, Akutensoushin mainly published doujins of Tohou Project, and later on they switched to Kantai Collection. Their doujins are always very hardcore. But ,they are my enlightenment works, which let me completely fell in love with pregnant girls and the plot of giving birth with ahego. They are one of my favorite doujin artists, in order to support the them, I bought some physical copies on Japanese website.

The classic doujins of Akutensoushin
Let’s start by reviewing some of the early interesting and useful works of Akutensoushin. In this stage, Kokutou Nikke’s drawing style was very unstable, and the characters often look very young. We can observe this from the doujin “たった五百円で早苗さんを犯りまくれる守矢神社, and their old avatars. In the early days, they always draw Tohou Project doujins, and the plot are filled with various ingenious ideas.

But sometimes it is a great pleasure to read the young girls with bit tittes, such as “フラクシナス 大乱交パーティー” the gangbang doujin of Date A Live.

They were known for their hard-core contents. “優曇華出産薬物調教” has the most tragic plot. The girl is being gang raped then forced to give birth in front of the men, but the child was trampled to death by the villian on the spot. And she is continued to be gang raped. What the fuck, I like this doujin very much.

The “virgin” doujin readers who are new to these kind of things may scared to death after seeing this, but I feel very horny when seeing them! The impressive hard-core plot is the main characteristic of their doujins. In the other hand, when reading “天龍お姉ちゃんとないしょの夜戦演習!” I just cannot like these sweet plots. Well at least, the boobies are still well-drawn, they looks very sexy and delicious. I can fap to that though.

The plot of giving birth is very common in Akutensoushin’s doujins. For example, “古明地こいし生命出産遊戯” has a plot of giving brith. The girl was selling her new-born children to the men for food. There is a funny thing: The Chinese translation group felt this plot is too cruel so they changed what the girl said in their translated version. How fragile their hearts are.

Akutensoushin gradually switched to focus on drawing character from Kantai Collection. The series title are often started with “艦娘着妊” When the fleet girls get pregnant. I think the most impressive one is “艦娘着妊 響出産性狂育”. The girl rides on the son of the admiral, and suddenly gave birth directly on his body when she is on orgsam. What a masterpiece! I cum to this many times.

The fate of girls from sixth destroyer division are very tragic. In “艦娘着妊 雷拘束劇薬調教”, after being mistreated to become unconscious, Ikazuchi had a beautiful dream with her friends. However, she had to wake up from the dream and face the reality, which is being fucked by lots of men. Her mind is fully destoryed in the end. What a pity. Well, this kind of mental breakdown plot is not that common in Akutensoushin’s doujins. In addition, this doujin is much about mechanical rape, I am not interested in mechanical fucking, so I don’like this doujin very much.

“艦娘着妊 電出産鬼畜姦” is the fisrt Akutensoushin’s doujin I read. Now it is still very good for fapping. Watching the little young bodies of sixth division girls being fucked and being forced to give brith is such a great pleasure.

When the change of drawing styles had begun
Kokutou Nikke like to share some funny comics of these poor girls on Tiwtter, to give readers a fresh view. For example, Inazuma becomes a long-suffering procuress after being fucked by many men. It seems that Kokutou Nikke had earned a lot of money in recent years (he startied to draw audlt comics for commeercial magazines), he started to publish some 総集編 (the clip show of previous doujins) and add few new contents in the book.
The drawing style of Kokutou Nikke (Akutensoushin) started to change in “艦娘着妊 タシュケントちゃんと楽しい建造エッチ”. In this sweet doujin of Tashkent, the man has to make love to Tashkent and let her give brith three times to finish the daily tasks (this is a refernece of the orignal Kantai Collection gameplay – you have to construct three ships girls daily), and the both of them enjoy of mating very much. What’s more, look at the following image, the POV of the scence. It seems like the artist is trying to break the fourth wall. It is like she is saying “Let’s have one more sex ~ admiral” to the readers.
“艦娘着妊 鈴谷売春出産” is a funny and enojoyable doujin. The poor guy throw his (empty) wallet to the bucket in order to become the first man to fuck pregnant Suzuya who is about to giving brith.
Personally I think “艦娘着妊前夜Prinz Eugen薬堕乳戯交際” and “艦娘着妊 Prinz Eugen & Bismarck 出産返済母胎提供” are Akutensoushin’s best works. The girls have drugs, become addcited to sex, and get pregnant. The pleasure of dominating women is fabulous.
Sometimes Akutensoushin would draw the scences of girls being fucked by interspecies, or their children, but I am not interested in reading these. Furthermore, the plots of “金剛ちゃんとラブラブ新婚プレイ” and “山風ちゃんは愛が重いっ!!” are too sweet, which are not that catchy and “useful” to me.
The problems of their new drawing styles
As the drawing style of Kokutou Nikke (Akutensoushin) stabilized since 2021, the birth and pregnanc plots became a bit formulaic. Although there are still creative storylines that are very enjoyable to read, but his drawing style is very different from before.
In the latest “艦娘着妊 Atlanta陥落 背徳快楽” doujin, the scences of pregnant belly, back position, cowgirl riding, tit fuck are stil well-drawn and sexy. The only downside is that his style has been stabilized and less exciting.
This is another sexy doujin seires: “艦娘着妊グレカーレちゃんと楽しいボテ腹H” Grecale, the dark-skinned, naughty and little girl is very horny. She is a cute and bad girl who could empty your balls in one night.
Kokutou Nikke rarely draws the scences of “insemination” but that’s not that important. However, after reading CrowView (たじ) ’s doujins, I realized that the more important thing is the pregnant belly: As we see above, Kokutou Nikke’s pregnant belly is not not realistic. For example, no stretch marks are drawn, which is not attractive enough for some pregnant belly lovers. In addition, the size of the belly at the time of delivery is often too small. It should be larger so the girls would become much like a mother who would give birth soon. Perhaps the small belly would be easier for men to try different sex positions. But this kind of belly does not give reader a stressful feelings – a pregnant and sexy woman is sitting on your top. Fortunately in recent years Kokutou Nikke has imprvoved a lot. Now the girls in his doujins and comics always have big pregnant belly.
Moreover, the fetus in the womb is often drawn in a very simple way. The fetus is always a black shadow, then the girl would have a “A-He” face when her cervis is being opened up by men’s dick. There should be more angles to show the appearance of the fetus in the uterus from a cross-sectional view, like this one:
CrowView (たじ) 峯雲プレゴリズム
As for the giving birth part of Kokutou Nikke’s doujins, we can always see these scense: First, the men would ejaculates on the head of the new-born baby when the girl is giving birth. After the birth, the men would keep cumming in the gilr with the umbilical cord is left inside her body. The men could feel the pleasure of having the cord wrapped around his dick.
The problem is that the new-born babies in Kokutou Nikke’s doujins are very small, so it is easy for the men in the story to pull it out and in with their dicks (Ha!). In addition, the vaginal wrinkles are not clearly drawn, and the vaginal lips are always just a small line or being covered by black censoring strips. This makes the birth process look fake, and the fetus seems could be pull out easily. What’s more, he men’s dick should have been bloody when plunged into the vagina with umbilical cord still left inside.
If you compare Kokutou Nikke’s doujins with other realistic artists, you will know that it is very important to draw the fetus in a very sexy way. When the fetus is coming out, the female character’s should be very fierce and painful, this is my first point. Then, when the fetus is born, his/her head will open up the vagina, so even if you want to put a lot of censoring strips on it, you can’t neglect to depict the scence of vaginal wirnkles being opened up by the fetus. It is like the vagina is sucking the fetus and at the same time he is trying hard to get out. Finally, the birth of the fetus should come with amniotic fluid spilled on the floor.
Another example of realistic giving-birth doujin: 新堂エルの文化人類学
In short, nowadays even though Kokutou Nikke’s new doujins have the elements of giving birth, the style of his drawing had became fixed and feels a bit commercialized, sometimes the drawing looks dull. Kokutou Nikke has started to publish adult comics in commercial comic magazines in recent years, so perhaps this is also the reason why he made so many big changes.
Wrapping up
I still love Kokutou Nikke’s old doujins which I listed above, and I keep use them for fapping from time to time. As for his new works, although the style of drawing has become dull, some scence are very good for fapping.
