minors in the Philippines
What's not well-known is that before Duterte's curfew pronouncements, many barangays and cities already have their own curfew ordinances, but they were not implementing them. It was only after Duterte won that they began to re-implement their own curfew ordinances. Duterte mentioned the word "unaccompanied minors" so maybe if there are adults supervising the barangay games late at night, then it could be an exception.
Based on the Anti-Rape Law of 1997, your sister's case cannot be rape because you said she did it willingly and she's not under 12 years of age.
About seduction and corruption of minors, her case might fall under these, depending on the status or position of the boyfriend in relation to your young sister, or if the boyfriend deceived your sister.
Remember also that in court, you have to prove beyond doubt the presence of deceit, or abuse of authority or power over your sister.
You should ask for advice from your parents. Consider also the situation of your young sister. Will she be strong enough to survive the effects of being shamed by the public, in case shaming occurs? What if the boyfriend's relatives and friends shame her on Facebook? Can she take it? Or you can demand (under threat of filing a case) the boyfriend and his family to come to an agreement that they spend for all pre-natal and maternity expenses and financial support in case this results to pregnancy. Seek advice from your parents and other loving trusted relatives that have authority. I hope you've already prayed and you continue to pray. And I hope you get the best advice from your parents or trusted relatives or other persons in authority (depending on how public you allow this situation to get).
Here's a copy of Title Three of TITLE ELEVEN of The Revised Penal Code that might be relevant to your sister's case.
