• Animation

The animation itself is not the best, although it was "a little too good" for this Title. There were instances when characters would look a bit "derpy" or disproportionate but even then it's far too good compared to the Story.

• Character Design

All the Girls have their own uniqueness and flavor according to Comic Character Template but their characterization was inconsistent. The children look completely like Toys,Robots,Pets and do not have any character development. The protagonist looks Okay not too Bad for this Title, rather this protagonist could have been used in better anime.

• Character Development

Honestly I feel like this anime or the whole 'story' itself is down the drain. None of the character developments were actually meaningful, rather there was too little or no Character Development. The little segments each character is given with the main protagonist is too little of a time to fully develop a meaningful connection or bond with the girls, it was just like they were forced to show some drama and there was not a single drop of "Love" effect which we feel from Romance Anime. Having a lot of characters for a series could have been be done in 12 episodes( even though rushed), but it could have been done and in a lot better way. There was a whole lot of potential for Conception, but there was No heart touching Talk, No Real Romantic Scenes not even Romantic Background, Characters never confessed love to other other, only blushed while Naked in the Bed, Main Character sometimes was either only concerned about SEX or sometimes cool, so cool that both situations were too Out of Character.

• Harem/Romance

Connections (Love Ritual) with the girls feel as lousy and meaningless as a one night stand, they never confessed, never talked about each other, never cared, just met spend 10 minutes, then go to Love Ritual. Like I said from my previous talking point, there's just enough time in 12 episodes season to introduce 12 characters and have a meaningful connection with MOST of them, considering even some hardcore rushing, but even there was the story events too out of place. Some of the maiden's interaction with Itsuki was so abrupt and meaningless, that it just can't even be called Romance. Some of the maidens fell for Itsuki with some cringe or cheesy 'cool guy' line and off they go to have sex. They could have used that opportunity to build more of a bond with the characters but nope, straight to sex they go. Also, when he hurt some character (Yuzuha), he instead of Going After her, he goes to Another Girl (Aries) to Have Sex then goes back after learning 2 lines from that girl (Aries) to say to the hurt girl(Yuzuha) to have sex with her now.

• Story/Plot

May include minor spoilers
No doubt one of the worst story/plot in anime I've seen yet. It starts off with the Itsuki and his cousin, Mahiru. No feelings seen between them after Mahiru says she's pregnant. Itsuki never showed Anger, Frustration, Sadness, Or even the emotion that he would have showed after knowing that he possibly got Cuckolded. After they suddenly get Transmigrated, They're then informed about these 12 maidens that exist that can give birth to powerful children, called the 'Star Children', who can fight against 'Impurities'. And of course, the only way to produce these 'Star Children' is by Itsuki developing a romantic bond with each of the maidens and having a 'love ritual', also known as sex. Also, it requires both of them to deeply care about each other from the heart to give birth to those children. Itsuki is given the duty to protect the world and slay the 'Impurities' to return back home with Mahiru. From surface level, it doesn't sound so bad, but the sheer amount of Unrealistic character developments is too overwhelming and the whole show just goes into a downward spiral. It had its moments when the story itself was actually going smoothly and you almost completely forget that the storyline and pacing was complete garbage, but they were too short to remember. And only Character who had a Character Development with Main Character was Mana, if the author even married them and they had sex, i would say this Anime really had Romantic Element. But no he had Sex with 12 Prostitutes who got paid in 10 lines of his time.

• Conclusion

Conception had potential. I really believe it could have been a great show if the series had a lot more character development and the anime wasn't constrained into only 12 episodes. It had the ideas and ingredients for a good series, but the execution just wasn't there. If you have 5 hours to waste, go ahead, no one is stopping you from watching it. Don't let the heavily negative reviews stop you from watching a series. One man's trash is another man's treasure, and it may just be your treasure. To show proof there is no Romantic Theme here, nobody ever got Jealous, Pouted or even gave a damn Expression when Itsuki fucked a girl and moved on to fuck another.

P.S. : Mana became my favorite character at the end. Most of the time I thought Mana's presence and existence was annoying, but Mana's presence also grew onto you slowly. It was a character development happening unexpectedly, one of the only characters to actually develop a connection with the viewer a bit. Mana was a curveball that I didn't see coming. Although Mana and Itsuki never had Sex, I can only ship those two together as lovers here.
