For all intents and purposes, the only people swapped for this Rikku's Spira are Rikku him/herself and his/her father and brother. This Rikku's dad died, and his mother (Cid) never remarried or had any children other than Rikku and his Sister (Brother).

Five of Rikku's spheres are available for purchase.

--Thief Got it!
--Lady Luck Got it!
--Mascot Got it!
--Psychic Got it!
