Lilin is the daughter of Gyumao and Gyokumen Kousyu. She is very hyperactive and always wants to go into a fight, though Kougaiji doesn't let her.
Kougaiji, though not willing to call Gyokumen Kousyu his mother, is very nice towards Lilin, as though he was her real brother. Lilin and Goku have plenty in common, both love to eat. Lilin calls Sanzo 'drooping eyes', calls Goku 'monkey', calls Goyjo 'Monster', calls Hakkai 'cook'. She always wanders what Rasetsu-yo is like, and she likes Yaone. She is always looked after by Yaone and not by her mother.
