Actually Muhammad, Amui's crystal was glowing in reaction to Tiga, he was Diago's ancestor and chosen to wield his own Spark Lens. It is uncertain but he is suspected to be Tiga's reincarnation before Daigo or simply that his genes, the Bronze Spark Lens and some manner of communion with the Tiga Statue allowed him to transform into Tiga, but no one knows for sure.
