A calm and peaceful naga who enjoys relaxing in the hot springs near her home. Terra lives in Chidokai forest, at the edge of the Soral swamp. She has a straightforward and understanding nature, enjoying comforting others, and is something of a philosopher. She possess a curious mind and, while she always enjoys a good hunt and occasionally eats humans like other nagas, she also sees them as interesting and complex creatures, in other ways than just being food. She's not that voracious for a giant naga, as she grows and eats many kinds of fruits and vegetables.

Born on a remote island, Terra and her sister moved inland after their tribe’s island was destroyed by a tidal wave. Her blood sister was killed by the dridder Eshka, and Terra swore to avenge her. Terra has taken Rin under her protection and tends to see her as a "new" little sister.
