​Tethu​ (Tethi when chosen as a female) is a Seedling that serves as the main character of Ever Oasis. He tries to repel Chaos by building an Oasis with the help of Esna, a water spirit.


Tethu is a Child of the Great Tree. Early in the game their older brother, the chief of his own Oasis, is wiped out by Chaos, shipping Tethu to the closest Water Spirit Esna. Together, Tethu and Esna decide to create an Oasis of their own and use their combined power to destroy Chaos once and for all.
