thank you! umineko is a murder mystery visual novel/game about a family on an island, and eighteen people die in two days as we learn more about how and why they all ended up... sort of awful humans, and about beatrice, the witch of the island who might or might not exist -- and then at the end of the first arc, it becomes an ideological battle between the main character battler and beatrice, to determine whether the murders were actually done by magic or by human means. many things we thought we understood come back in different forms and have to be reassessed in light of new information, so it's a really fun (and occasionally tragic) experience.
