Instead of "Trigger", the Neighbors' technology is referred to as "Neighbor Craft".
Jin is the protagonist rather than Osamu and Yūma, who are not seen in the manga.
According to Editor Hattori, the reason why Jin is the oneshot's protagonist is because Ashihara thought it would be a waste to use Osamu and Yūma in the oneshot, so he suggested using Jin instead and Hattori liked the idea.
Masamune Kido doesn't exist either, and Border's leader is Makoto Yuiga (similar to Makoto Chano and Takeru Yuiga). He also has a son called Tadashi, the leader of Base No. 7, who bears a resemblance to Takeru.
Border's branches receive number designations instead of names, such as Base No. 7.
