Rolling Updates, Needs a Better Description A sort-of sub-genre of hentai and ecchi harem stories, in which the main characteristic is that the girls in the Love Dodecahedron (or a Love Dodecaehdron-sized subset of the main Love Dodecahedron) are all sisters, most typically of the blood-related variety and sharing at least one parent between them all. The protagonist himself, however, is rarely related to the sisters. This can also often lead to situations where several of the sisters get it on with the guy at the same time. This trope is the result of taking the premise of Sibling Triangle up to eleven and blowing it to Love Dodecahedron proportions. Do also note that while it's usually "several sisters, one guy", cases of "several brothers, one guy" do exist, but are rarer than former variant due to Double Standard.
Examples:Anime & Manga
- To Love-Ru has Lala Satalin Deviluke, who is later joined by her sisters Nana Asta Deviluke and Momo Velia Deviluke.
- Genderflipped example: In Flora Segunda the mother of one of the main characters is married to three men who are brothers.
- Biblical example: Jacob and his wives. Leah and Rachel were definitely sisters, and some historians/biblical scholars think his other two wives, Bilhah and Zilpah, were full sisters to each other and half-sisters to Leah and Rachel as well.
