This is the best storyline so far of all yaoi i've ever read. It might get a little bit confusing at first, since it required you to think and imagine all sort of supernatural things that have been going on in the household. The people in this household are kotodama user, which made a living using words that contained power. They could make their business success, kill people, and all sort of things by speaking the words. In exchange, their body took damages accordingly to the deeds they did. The more horrible the deeds, the more damages their body got. Then, there are kami, human paperdolls. They were made solely for the sake of kotodama users. The kamis absorbed their master's wounds and got hurt themselves.
It will get better and better as you read it. This manga contains multiple stories of characters in the household. Sometimes it's simple and funny, sometimes it's a tragedy that will make you tear up.
There are three of many stories that really touched me.
1. Raizou - Kon couple. Their story was a heartwarming one. It was about the bright Raizou who fell in love with Kon, a young kami who always questioning about his purpose in this world.
2, Genma - Himi couple. It was about a boy who loved someone he couldn't touch. That boy grew up to be quite a twisted man and eventually binding Himi in every way possible so that Himi will always be by his side for the rest of his life.
3. Shoui - Asari. This one is really my favorite couple. It was about Shoui, he bore a heavy burden as the head of the house. Since young he wanted someone to be by his side, someone he could trust, and that someone happened to be his kami, Asari. Unfortunately, Asari actually hated him. Nevertheless, Shoui still bound Asari to him and loved him until the very end.
The art was good, but not exceptional. There were many sex scene, actually almost in every chapter, but somehow it doesn't feel perverted, instead it feels natural. The only flaw is that some chapter are missing in online reading site. But overall, it's a great reading.
