This manga has a lot of great ideas and not a lot of space to utilize them. The concept and premise intrigued me, and the manga works really well with what it starts out with. It suffers heavily by being only 13 issues (not counting the bonus chapter). It needs more time to really explore the character's relationship and the world that its built. It's interesting, it makes me want to read more. If it had more like 25 chapters it would be a top 5 contender (for me), but it comes out feeling rushed in the romance and rather vague with the world-building when therereally is something there that pulls one in. I really wish it had more time. I like robot yaoi.
