You really are nothing but trouble.
Keiss is a Selkie character from Final Fantasy Crystal Chronicles: The Crystal Bearers. Unlike most Selkies, Keiss makes an attempt to make an honest living within the Lilty Empire to achieve his dream of "stealing" the title of High Commander from the Lilties. He seems to wield multiple weapons; having been seen using throwing knives, a long sword, and a handgun.
Keiss is voiced by Noriaki Sugiyama in the Japanese version and David Vincent in the English version.
After his job of guarding the Alexis II airship, Keiss takes Jegran's offer for a reward of thirty million gil for the capture of Amidatelion, while asking for an alternate award. He later comes to Layle's aid in the Subterranean Ruins when he and the Yuke battle over the Crystal Idol. After a while of chasing after the Yuke, Keiss goes back with a strange-colored shard for Layle to get an analysis on from Cid.
By the next time they meet, Keiss has become a colonel in the Lilty Army. This, however, causes issues when Keiss juggles his friendship to Layle with his ambition. However, after Vaigali sacrificed himself to save him from Jegran, Keiss helps Belle expose Jegran and alert Princess Althea to avenge the Selkie Guild master.
When Jegran attacks him, Althea sacrifices herself to save him. After the Yuke Crystal's restoration, though offered the position of High Commander, Keiss turns down the chance. Instead, he becomes the new Selkie Guild master, keeping his tribe out of trouble, while uncovering any info on Layle's current status.
Keiss appears in Final Fantasy Trading Card Game as an Aqua-elemental card.
Keiss's name could be a reference from an Arabic name (قيس) which means "the strong one".
- Keiss has a pin strapped with his leather arm glove resembling to the Japanese demon-like ornaments worn by samurais. This may reference Keiss's honor (similar to the said samurai motif) and desire to make a life clean of thievery, which is popular in his race. The ornament has slight similarities with Vaigali, the Selkie tribe leader. The bandana is similar to that of Stiltzkin, although it is different in color.
