Yūgo Kuga
Kido orders Jin to obtain the Black Trigger from Yūma. Meanwhile, Yūma and Chika are discussing Yūma's past and Neighbors in general. When Chika said that she heard about Yūma's motive for coming to Earth, she questions him on his father. He responds that he was a weird person, using his father's three rules as an example. The topic moves on from that to kidnapped humans. Yūma explains that those with high Trion were generally well taken care of, asking Chika if she knew any kidnapped people. She denies it, but he detects it as a lie. She then admits that she knows two people who were kidnapped: her friend and her brother.

Yūichi Jin and Arashiyama Squad vs. Border's Top Teams
After their return from an expedition, Kido assigns Tachikawa Squad, Fuyushima Squad, and Kazama Squad to join Miwa Squad in their mission to take Yūma's Black Trigger. They are confronted by Jin and Arashiyama Squad and engage in battle. Although they fought well, the top teams of Border are no match for Jin, Fūjin, and his side effect, topped with Arashiyama Squad's help. Headquarters loses the initiative, however Jin shows his face and gives up his Black Trigger to ensure Yūma's enlistment.
