The former commander of the now defunct 8th Squadron of the Demon Slayers. There are records which state that while Libera was surveying the Vriksha region， she left information behind regarding the territorial dispute among the Four Fallen Gods， and about demons. When considering the fact that the region she was surveying was under the control of Afla Dilith， one can truly appreciate the level of expertise Libera used to complete the task. It is safe to say that the Summoners of Old owe their knowledge of Grand Gaia's current state to her incredible efficiency.
