Aji approaches a confused Janu, and together they flip the card, revealing a message: "Open Fight" with an address underneath: "Benteng Utara." Curious, Aji urges Janu to visit the place. Though hesitant at first, Janu eventually agrees, pushed by Aji and his own curiosity. When they arrive, they discover the location to be an illegal fight arena for high school students. Pressured by circumstances, Janu is drawn into the fight, ultimately defeating the strongest fighter there.
