Repatriation (送還 Sōkan) is a summoning spell to send the summons to a safe place, or back to where they originally inhabit, in order to protect them from receiving more damage. To summoners, protecting precious summons from unnecessary damage is equally important as summoning them for battles. In StrikerS, it is cast by Lutecia Alpine to repatriate Garyu, and then Jiraiou when Caro Ru Lushe's Alchemic Chain interrupts. Presumably Caro also casts this spell to repatriate Voltaire.
