It's one of the best conan fics I have read. The mc gets constant stream of knowledge from different worlds and because of it is sleeping most of the time. The Heroine of the novel is Ai and the relationship and interactions are good and subtle, and she doesn't fall in love or become dependant in there meeting. The novel is. Mostly slice of life and doesn't follow conan all the time, plus the most cases are ignored by mc and if not completely changed.
