I call it the spyxfamily AU art bc it seems to imply

1) this is a slice of life comedy show about two secret agents who accidentally acquire a child

2) akam + conan are the main characters. they come as a pair and conan is their precocious child

3) they get along swimmingly and regularly go on cute little dates with their son

(On a side note akai likes staring at amuro in a lot of these)

Bonus: offical art where they are divorced and share custody over precocious kid conan
