Tida

Tida is a wandering sister from the Church of Ibris who goes from villages to villages to heal people. Elizabeth and Tida have the same age. Elizabeth meets Tida for the first time on the route to the capital. At first Elizabeth is cautious to not sin in front of the sister... before discovering Tida is the biggest sinner in existence. If the series itself is quite dark, Tida is actually a comic relief who adds fun to the series. The Manga readers gave her the nickname NINO for "Nun In Name Only", because she acts nothing like a nun. Since she's a walking sister, her element is Light, she uses her element to heal people.
