The hybrid child is a doll that grows older when their owner shows him (because the dolls we are shown in the anime are, of course, male due to the yaoi aspect) love. In this anime, we are given three stories of their owners loving their Hybrid Child.
The three stories effectively show the bonds between humans and their hybrid child. In the final story, it becomes more of the bond between two human men, one of whom is the creator of the hybrid child. We get a sense of how his project really grew to be his life, and how it changed the lives of the two men in the previous episodes.
The characters are all different from each other, as is the relationships between human and hybrid child.
Kotarou and Hazuki in the first episode bicker and banter, but when Hazuki's life is at stake, you see how strong their bond is and how far Kotarou is willing to go for him. The additional story within the episode of how the two came to know each other is especially touching.
In the second episode, we have a young hybrid child and an older man. This is not a perverted story, mind you; this one is about the hybrid child, Yuzu, questioning why, after all the time he's been with Seya, he hasn't grown yet. Does Seya not love him?
The last story is without a doubt what makes the story: this is the story of Kuroda, the creator of the hybrid children, and how his love for Tsukishima drove him to create all of these hybrid children.
The art is something one would expect from a yaoi when it comes to the characters: they do share the same facial shape. Think of the characters from Junjou and Sekaiichi (all by the same author) and you'll understand. However, the backgrounds are superb. I found myself pausing every so often to admire the scenery, as it's very well done. I appreciated the attention to detail.
The OP and ED aren't noteworthy. There's classical music throughout the anime, helping to evoke emotion within scenes. It's used effectively and upon second viewing I did find myself enjoying and appreciating the music more.
I enjoyed myself a lot. Just like with Junjou and Sekaiichi, I will add Hybrid Child to the list of things I will watch over and over again.
