Completing special missions will sometimes give you Elder Kais as a reward, they will sometimes be given as a bonus when you do multi summons on some banners(it will be clearly visible when that happens), and sometimes there are special Elder Kai banners where you can summon either 5 or 10 depending on the banner. Some story events also have special currency you can farm that you can exchange for various things at the Baba shop, usually there will be at least 1 Elder Kai available there.
