Background
Petos is send to the Golden Panther tribe village and obtained a possessed "Matches" sample. he reaches the village and informs the branch family tribe that their village has traces of possessed, where he heads to the tribal chief's house. He persuaded the tribal chief to give up his daughter, but he replied to him that he lied and say that Demon possession is the scrutiny of the Holy Church.

He says to the chief that he has proof for that statement, which he replied that their tribe have a long-standing bloodline of a Beastkin hero and tell the real truth about the three heroes and the demonic possession. Petos lied about his true statement by saying it's a blasphemy against the Holy Church.

The chief continues that he been curious about the story of heroes and demon, which he confirm that the fairy tale story that was passed down in the golden panther group are the truth, while The Holy Church distorts it, making Petos expression seems irritated about his confirmation.

Then, the leader of branch family threatened the chief to say where his daughter, but he refused. When the chief's daughter revealed herself, her father says to her that she must fulfilled her mission by heading to the east at the Midgar Kingdom, to find someone who will cure demonic possession and tell his wife to with their children while he stay behind to protect them from his tribe and Petos, to which he activated the power from the Beastkin hero, Lili.

Petos surprised by the chief's attractive power, which he never thought would be her descendants in this village. He decides to attack him because he feels that the gathering demon possessed will be an unexpected advantage. Petos kill the chief by cutting his head and carrying it, also ordering his men to taken care of all the members of the golden panther group by killing all of them, so there will be no information leakage of the real truth of the Three Heroes and demon Diablos's story.

Then, Petos searched for the possessed chief's daughter. By chance, he found the chief's wife and beheaded her, while carrying her head. Petos found the girl, carrying her baby younger brother at the beach and showing the severed head of her parents. He walk toward her and demanded to know which one of them is a possessed, which the girl replied honestly.

When the girl screams at him that she will kill him, while holding her family severed head, Petos ignored and turned his back on her, which he called his subordinates from the forest to confirm that the tasked is completed by showing all severed heads of the golden panther tribe to her, including the branch family leader.

The girl then charged towards Petos, but his chains sent her flying. Petos order his men to arrest the girl and send her to Valliora's laboratory, while he makes preparations to form his faction. Soon, Petos received word that the girl from the golden panther tribe had escape by unknown group, to which he then became obsessed with finding her whereabouts.
