Parallel Paradise manga volume 9 features story and art by Lynn Okamoto.

When Yota and the girls retreat from the sinister witch Galia, the last thing they expect to encounter in the underground ruins is a childhood friend. But wait, isn’t the jealous god supposed to reside down there…? Meanwhile, Galia descends on Meese Town, hungry for sacrifices and sowing disaster. Misaki takes the new Guardians to confront the witch, but how can they hold out against a power as ancient and sadistic as hers?
