Tsukihiko Amō/Plot

Black Trigger Capture Arc
Kido threatened to send Amō after Yūma when Shinoda announced his joining in protecting Yūma. Everyone at the meeting was shocked, because of Amō's sheer strength and inhuman demeanour.

Large-Scale Invasion Arc
He is sent to eliminate Trion Soldiers in the south with Jin. He ends up obliterating the area, and then takes over Jin's area, much to his disdain. After the invasion, he receives a special service award for protecting the city and preventing loss of life with him also defeating 3 Rabbits.

Galopoula Blitz
He is recommended by Azuma to be employed due to his Side Effect being useful for the situation. During the invasion, he observes the outside forces from within HQ and notices three outliers in strength; those being the 3 humanoid Neighbors. He notes that one of them has strength that rivals that of Shinoda.
