Other name: SILVER DIAMOND外伝; SILVER DIAMOND外伝 くらやみの地図
Summary: The extra story elaborating on the meaning of Rakan's miracle is an absolute gem!! "Map of Darkness", which depicts the Guards' life before meeting Rakan,"The Last Shelter from the Rain", their reunion in the alternate world years after the final battle, and 9 pages of extra stories such as "The Slope of Yomotsuhira", etc. are also worth-seeing!!
