I don't understand Being X's actions. Tanya was granted the reincarnation because the original slipped up and told Being X that only people lacking material and immaterial wealth would believe in a god, whereas he, who had a solid career and an even more solid personal philosophy would have no use for a god. So, why was he reincarnated as a super powerful magician? It would have made sense if she was reborn simply as one of the nameless orphans struggling for their daily bread, but instead she got out of the orphanage and into the military whilst still nothing but a little kid due to her one in a million talent. How will that help her to discover God, huh?
