Amano interferes to report Gasai's parents' abuse of her to the police.
But God Gasai arrives to take her own place, and she's grabbed some insurance: Amano's parents.
Ninth and Amano flee with young Gasai.
Ninth tells Amano he's better make up his mind who he wants to save.
Ninth calls Fourth to warn him about his son's heart disease.
Gasai would fall for anyone who allowed her to cling to them. Amano would fall for anyone who protected him.
Clearly the right way to solve this is to seal him in an illusionary world where she doesn't exist.
