In Jainism, there is a concept called Naav Tatva (Nine Fundamentals), but this refers to nine fundamental principles of Jain philosophy—not to sets of hero, villain, and brother.

However, your question seems to refer to a narrative tradition sometimes found in Jain storytelling, particularly in relation to Jain Mahakavyas (great epics) and Prabandhas (narrative tales), where the stories are constructed around three main characters: the hero (Nayak), the villain (Pratinayak), and the brother (Anuyayak or Sahodar).

In Jain tradition, there are recurring sets of stories where these three archetypes appear across multiple tales, especially in the context of the lives of Tirthankaras or other great souls. However, the "9 sets" is not a standard doctrinal division in Jain scriptures.

If you are referring to the famous Navapada or Navatattva (Nine Principles), these are:

1. Jiva (Soul)
2. Ajiva (Non-Soul)
3. Punya (Merit)
4. Paap (Sin)
5. Ashrava (Inflow of karmas)
6. Samvara (Stoppage of karmas)
7. Nirjara (Shedding of karmas)
8. Bandha (Bondage of karmas)
9. Moksha (Liberation)

These do not correspond to hero, villain, and brother.

If you refer to the Jain narrative structure with triads of characters in famous stories, please clarify the specific text or context. In Jain literature, particularly in some retellings of the Tirthankara lives, certain stories are built with these triadic sets, but there is no doctrinal list of "9 sets" with hero, villain, and brother as a philosophical or scriptural teaching in Jainism.

Summary: There are not 9 canonical sets of hero, villain, and brother in Jainism as a doctrine. If you seek nine fundamental principles, those are the Navatattva. If you seek narrative triads, please provide more context, but that is a literary device, not a doctrinal teaching.
