First in a series about a yakuza heir and his shield.
Second in the series about a yakuza heir and his shield. Includes X Side extra.
Third in the series, and it's getting spicy.
A man known as the "boss's public toilet" and his new underling/shield. You will cry.
This about about a yakuza heir and a man who is a preschool teacher, but was raised by yakuza. Technically not y/y but I'm counting it.
Technically loan shark and the boy he raised to a man, but all the same.
Focuses on the young romance of two yakuza members.
Straight yakuza love story. Kinda weird, plot is not as good as some of the others, but tolerable enough read.
