About
Trident City, a place where heroes and villains coexist. Villains threaten the citizens, engaging in various illegal acts and terrorism. Heroes are those who stand against such villains. Hero rankings range from Class E to Class S, with Class S being the highest tier. Guest, Khaki, Kaito, Line, and Pyros have been like family since childhood, relying on each other and growing up together. Guest and the four made a childhood promise to stay together forever. "Let's stay together for the rest of our lives!" N years ago... The Chairman of the Hero Association, Chairman X, was actually a villain involved in various corruption and embezzlement schemes. Guest realized this but felt that evidence was needed. Working alone, Guest collected proof of Chairman X's corruption and embezzlement. Once the evidence was gathered, Guest went to Khaki, Kaito, Line, and Pyros to reveal Chairman X's misdeeds and showed them the evidence, suggesting they take him down together... But... Upon hearing Guest's evidence, Khaki, Kaito, Line, and Pyros immediately set off to kill Chairman X. Guest stood before them to stop the four. Guest said, "There are many ways to win without fighting...! Please, listen to me...!" It was impossible to stop them, as they were already consumed by a desire for revenge against Chairman X. In the end, Guest stood against the four to prevent them from becoming murderers, but it was not enough... Ultimately, Guest collapsed with severe injuries, and the four branded Guest a traitor who protected Chairman X. Soon after, they killed Chairman X and put an end to the corruption and evil within the Hero Association... However... Killing Chairman X without evidence caused immense chaos. A way to win without fighting... Guest had intended to officially bring down Chairman X using perfect evidence... They thought about it again. "A way to win without fighting." Realizing their mistake, they immediately went looking for Guest... But Guest had vanished, leaving behind only the evidence of Chairman X's corruption and embezzlement. Pyros, Khaki, Kaito, and Line officially submitted the evidence Guest had gathered, closing the case and bringing peace to the Association. But they had lost Guest. And now, Chairman Y leads the Hero Association without issue, ushering in a golden age for heroes. Time has passed; Guest, Khaki, and Line are now 23, Kaito is 25, and Pyros is 22. Khaki, Pyros, Line, and Kaito still regret their actions and miss Guest dearly. If only... I had listened to you then...
