Sagi is a little boy who appears in the room where Dead Peppers grew in Herba's Mansion, found by Lisa who is the only one to see him while others can not. He actually turns out to be the manifestation of a Sagiso Flower that Lisa had raised as a child and was forced to leave when she moved to her mother's home, with Lisa feeling guilty for not recognizing Sagi until it was too late. In the language of flowers, the Sagiso means "my thoughts will follow you into your dreams".
