Progressing smoothly with the purification, she is confronted by a tentacle monster in the deepest chamber.
Distracted by the enemy's fierce assault, she was swallowed whole from behind by another monster.
Helpless, she continued to be swallowed until she loses consciousness.
When she wakes up, she finds herself bound by flesh walls and toyed with by tentacles...
This is the tale of the saint, who has been turned into a breeding ground for tentacles.
