Tsukihiko Amō

Tsukihiko Amō is an S-Class agent and a Black Trigger user.

Appearance
Amō is a young boy with messy neck-length black hair and narrow, greyish-yellow eyes.

Personality
According to Karasawa, his behaviour is troublesome and could pose a potential liability for Border if publicly displayed. He seems to be a thorough person, going so far as to destroy a large portion of the Forbidden Zone when defeating Trion Soldiers during the invasion. He also seems to enjoy fighting.

Relationships
Yūichi Jin: He seems to have a good relationship with his former fellow S-rank agent. He fulfilled Jin's request without much complaint and was later seen enjoying some of Jin's rice crackers with a blissful look on his face.

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 Warriors 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. He defeated 3 Rabbits.

B-Class Rank Battles Arc
He is recommended by Azuma to be employed in case another large-scale invasion were to occur due to his Side Effect being apparently useful.

Abilties
Amō is extremely powerful Black Trigger user. He was able to obliterate a portion of the city, getting rid of Trion Warriors, including 3 Rabbits in the area. He referred to them as small-fry despite the fact that one Rabbit was enough to capture an A-rank level opponent. Karasawa noted that he was superior to Jin in terms of raw power, and at the very least equal to him in overall combat. Shinoda pointed out that sending him meant destruction of the city. He has a Side Effect, though unknown, but it is apparently useful for preparation for an invasion.He seems to be able to distinguish trion soldiers from a distance by their colors.

His Trigger power seems to cause widespread and, perhaps, indiscriminate destruction. His Trigger is referred to as a "power-type" whereas Jin's Fūjin is a "Jin-type," which probably refers to Jin's sneaky nature and reliance on finesse rather than brute force.
