Umineko no Naku Koro ni Murasaki: Forgery of the Purple Logic (うみねこのなく頃に紫: Forgery of the Purple logic, lit. When Seagulls Cry Purple: Forgery of the Purple logic) is a manga-exclusive extra arc of Umineko no Naku Koro ni written by Ryukishi07, illustrated by Kurumi Suzuhiro, serialized in Comp-Ace magazine, and published by Kadokawa. Noticeably, it is the only spin-off to share the When They Cry 4 subtitle with Umineko no Naku Koro ni Chiru, whether intentional or not.

The story expands on the use of the Purple Declaration introduced by Bernkastel in her game in Twilight of the Golden Witch.

Forgery of the Purple Logic has not been officially translated yet nor has it been licensed for release outside Japan.

Plot Summary

Main article: Umineko no Naku Koro ni Murasaki: Forgery of the Purple Logic/Plot Summary

After winning a game against Battler, Beatrice starts another game. However, this is a game focused entirely on the whodunnit; no magic or fantasy scenes are involved. If Battler loses again, it would mean he really is incompetent. Beatrice also creates a detective character, Erika Furudo, to serve as the main character of this new game.

Forgery centers around the use of Purple Statements. Characters who are not culprits are telling the truth when they speak in purple, but culprits (ie those who have killed someone) may lie when they use purple.

On the final page, the author gives three questions for the readers to answer. Readers were able to send their solutions to Kadokawa, with a contest held to determine who had the correct solution. Afterwards, the true solution was published on the Comp-Ace website.
