Origin
Unknown for sure, possibly China
Seiga is a rather prideful girl who thinks Taoism is superior to other religions and tries to get people to convert. She acts to further her own goals, and nothing more, which is why she is labeled a wicked hermit and not accepted by the heavens. She doesn't seem to care about anyone, instead manipulating them for her own ends. Her revival of Yoshika's corpse shows her lack of regard for human rights. She doesn't appear interested in material possessions at all, despite her ability to pass through walls. However, in Symposium of Post-mysticism, she does take on a role of reverse-Santa Claus and steals people's belongings to sell back to whoever they bought it from. She dislikes Byakuren Hijiri and eagerly waits Toyosatomimi no Miko's revival. She is, however, very fond and proud of Yoshika Miyako and treats her more as a pet than a normal servant. She is someone who follows those she likes, but feels no particularly obligation to such people, making her alliance with Miko less assured than the other Taoists.
