Feliss

About
Feliss was originally a 6th Class Devil, and is currently bound by contract with Rance. Ever since meeting the latter, she experienced misfortunes and was demoted several times. It's for this reason that she doesn't like him and has even been happy at the thought of his death.

For Rance she's mainly providing service in battlefield and in bed, she also serves as Rance's personal informant and as events occur, provides important information that would otherwise be unknown to him. She also conceived Rance's first child, a devil called Dark Rance (not his real name, but a nickname given by Sill), which has given her a status of a criminal between Devils, since having a son with a human is against the Devil's rules. She was saved by Rance and is being kept safe in the Rance Castle.

She used to be a member of the Kalar race but due to soul pollution she became a Devil in her Time of Change instead of an angel. She conserves her Kalar Crystal but she won't die if it's removed, although it still scares her if people touch it. It is unknown when she became a devil, but she's been alive since at least the era of the Holy Magic Sect, which means she's over 500 years old at least.

Rance 02
Feliss made her appearance after Rance unintentionally summoned her via the Devil Talisman. Believing that Rance summoned her because he wanted something, Feliss offered him three wishes in exchange for his soul. The first wish was to allow Rance to do her, the second was a peach apple needed for current quest, and as for the third, Rance wished that she would not take his soul. Unable to refuse, Feliss disappeared into the darkness while crying.

Rance 3
For her failure to take Rance's soul, Feliss was demoted from 6th Class Devil to 9th Class Devil and had her job changed from collecting souls to be a sentry.

During his mission to save Kathtom, Rance found his path blocked by Feliss, whose job is now guarding Devil's Passage. Feliss despised Rance for causing her demotion and made sure that he couldn't pass. Failing to defeat the Devil, Rance and the others decided to retreat to think of another way.

Rance eventually found out from Priestess Rose that a devil would have to swear loyalty to someone who knew their name. With the help of Rose's devil subordinate, Da Gale, Rance managed to find out Feliss' true name and enslaved her.

Rance 4
Feliss was called upon to explain the history behind Ylapu.

Later on, she provided Devil's Nectar, which Rance delivered to the witch Frostvine, who used it to create Athena 2.0.

Rance 5D
During Rance 5D, she becomes pregnant with Rance's child. Usually, it is impossible for a Devil to bear a human's child. However, during the events of Rance 5D, she was trapped within a time-space anomaly where the regular laws of nature do not apply.

Rance 6
For the crimes of bearing Rance's child, Feliss was demoted to an 11th Class Devil. In addition, she was also sentenced to be raped and give birth to other Devils for a thousand years.

She was eventually saved by her child and Rance, however, the torture she experienced left her psyche broken.
