Silver Eyes are objects in the world of Kill the Past. They appear in The Silver Case and Flower, Sun, and Rain. They grant supposed immortality to those who replace one of their own eyes (consistently the left eye) with a Silver one. However, the exact powers of the Silver Eyes are unclear and have been said to include the aforementioned immortality and youth, indirect immortality through transferring to another body, and the ability to loop time. It is revealed that Lospass Island is actually a breeding ground for the rare breed of hyenas that have the Silver Eyes. Sundance Shot, Tetsuguro Kusabi and Tokio Morishima all have Silver Eyes (as of FSR at least).
The first Silver Eyes found by the government were originally discovered to have been implanted into Kamui Uehara. During The Silver Case, the elderly politicians kill each other over the eyes, with Uminosuke Hachisuka being the sole victor, putting both eyes into himself and becoming immortal. After this, the FSO Party begins the Shelter Kids Policy, with one of their goals being "ocular silverization", although they are never able to reach it. ELBOW after this discovers Lospass Island and begins production from the hyenas.
Possible Silver EyesEdit
There is some speculation that the God-Hand and God-Killer in killer7 are potentially related to the Silver Eyes, due to their owners having immortality and strange powers. Kevin Smith seems to have white or silver colored eyes that are said to glow in the dark, but his planned plot significance is never mentioned in the game. (Interestingly, in the flashback cutscene in the Union Hotel, his eyes are normal; this may or may not be part of his disguise.)
It appears that Mondo Zappa's left eye glows with power when he uses his silver Ulti-Mondo form. What this means in relation to the Silver Eyes of past titles is unclear.
The protagonist of Kurayami Dance has an odd-looking eye that is drawn the same way that Silver Eyes have been drawn in past illustrations. However, his special eye is in the right socket, unlike every Silver Eye; other scenes show two different colored eye implants, a lighter one for the left socket and a darker one for the right socket.
