Nanao X Aoi.. Manga is seious but its nice when they get together..
Aoi joins Shiki, an organisation.. he is teamed with Nanao.. Nanao is attracted to him from the start.. but Aoi has an ulterior motive to take revenge on their boss who killed his father.. but Nanao kills him in his stead as he know that Aoi would be half dead if he killed the boss as he is not a murderer.. Aoi is someone precious to Nanao..
NANAO TAKES REALLY GOOD CARE OF AOI.. ART IS NICE..
