Tsukihiko Amuo Age: 16 (High school student) Birthday: December 3rd Height: 165cm Zodiac: Cetus Blood Type: A Likes: Water, hamburgers, chocolate, fighting strong opponents Affiliation: Border Headquarters Rank: S-Class Agent Title: All-Rounder Trigger: Black Trigger (Name unknown) Border Normal Trigger Side Effect: Can see the strength of a target as color-coded visuals. 《Personality, etc.》 A boy with a downer vibe who speaks in a listless manner. He has messy black hair and wears a hoodie. An S-class agent who possesses a Black Trigger. The Black Trigger he owns was left behind by former Border member Tetsuya Umezaki. It is said that in terms of pure combat ability, he even surpasses Jin, a fellow S-class agent. Now that Jin has let go of Fujin and become an A-class agent, Amuo is Border's only S-class agent. He is likely the strongest individual combatant within Border. According to Karasawa, he has "various behavioral issues," but so far, no combat has been depicted, and he has only shown a calm side. Rather, during the large-scale invasion by Aftokrator and the battle with Galopoula, he performed his assigned duties properly, even if he occasionally seemed bothered by them. During the large-scale invasion, he mentioned that he couldn't get motivated by weaklings, so he might show a different side against strong opponents. The details of his Trigger are unknown, but his fighting style is said to be somewhat inhuman; in the conceptual illustration in Volume 4, his silhouette during combat is not human-shaped. In the large-scale invasion, he annihilated Trion soldiers along with the buildings in the warning zone, turning the area into a wasteland, suggesting he is a wide-area annihilation type. The land he cleared is filled with numerous craters, as if meteors had fallen. According to Utagawa, he is a power type. Because his way of fighting could lead to a decline in Border's public image, Netsuki, the PR head, is cautious about his deployment. It is apparently very bad for citizens to see him fighting. Even Netsuki muttered during the large-scale invasion, "He's reliable at times like this." The Border Briefing File (BBF) lists his parameters when using a Normal Trigger, and even without a Black Trigger, he is thought to have A-class level ability. His position is All-Rounder. His parameters when using a Black Trigger are listed as "Secret" in the BBF and have not been revealed. He joined about 3 years ago, but the circumstances of his enlistment and when he became an S-class agent are unknown. His family structure is also unknown. His first mention was in Volume 4, but while his existence was revealed at that point, he did not appear in person. Commander Kido, who took a stance of total resistance against the allied Tamakoma and Shinoda factions, tried to deploy him in the Black Trigger capture operation, which angered Director Shinoda, but because the conflict was settled by Jin, he did not actually participate in the fight. In the large-scale invasion, he handled the northwestern area of the base alone and later took over the western district that Jin had been handling, completely annihilating every single approaching Trion soldier (including three Rabbits, a new type of Trion soldier). Although the district he was responsible for was turned into a wasteland, he was awarded a Special First-Class Merit because he kept human casualties to zero over a wide area. In the battle against Galopoula, he supported the agents by utilizing his Side Effect. In the Away Mission Test, he does not seem to be an examiner, but he watches the footage of the temporary units in the same monitor room as the A-class agents. Rokuro Wakamura is a senior by one year at the same high school, and during this test, Amuo makes harsh comments like "He's flinching" and "His basics are completely lacking." Furthermore, the fact that he only comments on Wakamura among the temporary units hints at a relationship that is more than just being a junior. 《Tsukihiko Amuo's Side Effect》 It seems to be related to color, but the details are unknown. There are depictions where he can see the strength of a target he looks at as colors. In the large-scale invasion by Aftokrator, he described the swarm of Trion soldiers as "weaklings with boring colors." From this line, many readers predicted he had a Side Effect, which was confirmed in Volume 14. In the Galopoula battle, Azuma suggested in the strategy meeting to borrow the power of Amuo's Side Effect, and he checked the enemies on the battlefield via monitors in the HQ command room. In this battle, he saw through the enemy's strength one after another: Trion soldier Idra: "Color-wise, they're like lower B-class" / "When they gather, the color changes a bit." Idra disguised by Galopoula soldiers: "The ones with different colors." Trion soldier Dog: "Colors that feel like they're mainly for disruption." Galopoula soldiers who infiltrated HQ: "Good colors, A-class or higher." Gatlin: "In terms of color-coding, he's similar to Mr. Shinoda." Idra controlled by Yomi: "The colors of the two are the same." He can grasp not only simple combat power but also changes in strength due to group coordination. Also, from the depictions at this time, it is inferred that this ability is effective even through camera footage without actually seeing the real thing.
