Revy does most of the fighting for the Lagoon Company. Very little is revealed about her past, although portions can be pieced together through the series. Revy is a Chinese-American born and raised in Chinatown, Manhattan, near Mott Street, spending most of her youth as a thief and murderer. Flashbacks throughout the series reveal that Revy may have honed her skills with firearms by shooting at cans, and that her first murder may have involved shooting an unknown man while using a pillow. It is unknown whether the pillow was used to suppress the noise or to help avoid looking at her first victim. Revy is very competitive, easily bored, and extremely ill-tempered. Unlike Rock, she is undiplomatic, believing in the use of brute force and coercion to get her way. In contrast to this, she's revealed to be highly ticklish.

Simon is the protagonist of the story, a short and un-intimidating fourteen year
old boy at the beginning of this tale. He was born in Jiiha Village and was raised by his parents until
the age of seven, when his parents were killed in an underground avalanche caused by an earthquake.
Their deaths traumatized Simon to the point of both hating and fearing life underground, and likely
played a role in developing his relationship with Kamina. Ironically, Simon's role in his community was
to dig more tunnels and caverns to expand Jiiha Village deeper underground.
