Contract with Bodhisattva

The fruit of an evil act in the Buddhist world is to achieve positive results, rescue parents, sign a contract with Bodhisattvas, and enter the six realms of reincarnation (the heavenly realm, the human realm, the asura realm, the hungry ghost realm, the animal realm, and the hell realm). Can she achieve enlightenment and enter Buddhism? Can the Bodhisattva abide by the contract and let his parents go?
