Familia Chronicle (ファミリアクロニクル) is a Japanese light novel and manga series written by Oomori Fujino. Each volume will feature a different character or group and will touch on their past, due to not being able to do so in Danmachi or Sword Oratoria, however the author states that there's a chance certain characters will have multiple appearances.
The idea for the series originated with Episode Ryuu, which was formerly titled Grand Casino wo Buttsubuse, but was later changed to the current title to accommodate other characters. Unlike the other series, the author mentions that each episode will be published in parts as a web novel until the respective volume is released. This will only apply to the first chapter as the second chapter will be written specifically for the novel release.
Familia Chronicle Episode Ryuu is illustrated by Niritsu for the light novel and Momoyama Hinase for the manga. It features Ryuu infiltrating a casino to save a kidnapped city girl.
