アンバーブレイカー

Amber Breaker infiltrates the enemy's lair in search of the missing Ruby and Lapis. However, she too gets caught in Zodiac's web and, at his mercy, is consumed, body and spirit, in an unimaginable maelstrom of agony, humiliation, and ecstasy. To make things worse, the allies Amber came to save appear before her, and at their hands, she suffers mind-breaking and body-crushing euphoric torture. Just what waits at the end of her journey?
