About This Content

The addition of a new Heroin!
Enjoying the story of Elvish Paladin Frina Ciel.
Let's solve the puzzle and liberate her from"The World of GLASS"!

A leader of Elvish Knights, always wielding a giant shield and wearing full-body armor to battle.
A shining example of the Divine Paladin, smiting down evil with holy magic.
Though she speaks only rarely and her face is hidden by a helmet, rumor has it that she is actually a great beauty.
Thus a Frina fan club has formed already within her goup of knights.
On this day, as per usual, the virtuous Frina was smiting down evil.

But when she was momentarily separated from her knights, a band of goblins and orcs caught her off-guard and she was disarmed.
Her pure spirit was determined not to be tainted, but the monsters, all laughing hideously, rushed at her.
Goblin and orcs are especially infamous for their carnal urges. Frina was in danger of becoming a sexual slave. She closed her eyes,
anticipating a miserable fate, but no harm was done to her. A while later, Frina opened her eyes and found herself
trapped inside a mysterious glass structure.
