Viki

Viki is the Chitatsu Star in Suikoden, II, III, IV and V.
She is a magician who uses the Blinking Rune to teleport. Along with Jeane, she is one of the few characters to appear in every major Suikoden game. In her posession is a magic mirror which may or may not be an enhancement to the Blinking Rune's power allowing teleportation across the world (which is a greatly increased effect of the normal Blinking Rune). Dialog in Suikoden III also hints at the fact that Viki is able to teleport through time, leading to unfonded rumors that she actually carries a True Rune, and that she comes from a future period later on than any of the Suikoden games have yet taken place. Dialog from the same game also suggests that she might be a historian of some sort, visiting past periods and playing a part in decisive events. Despite being present in each game, Viki remains a mysterious character. She usually appears to be a female in her 20s , but is somewhat scatterbrained and ditzy. At times she seems insecure, either about her own actions or about the world around her. The act of sneezing seems able to distract her and muddle her concentration and mastery of teleportation.
At one point, a younger version of Viki was encountered, who seemed a lot more knowledgable about world events and significantly less scatterbrained.
One unfounded rumor from fans is that the non-linear chronology of the Suikoden games (e.g. Suikoden IV takes place 150 years before Suikoden) is because it actually follows the travels of Viki through time and is thus out of order.
