About half a year before the AgitΩ story happened, the passengers of Dawn sailing in Seto Inland Sea found a young man in white (corpse) suddenly appeared in the cabin. Then I was attacked by a strange storm. Suddenly, the young man in white appeared again and gave Tetsuya his strength. Everyone was illuminated by his light. Later, a mysterious ball of light broke in, and the water angel appeared in front of everyone, killing Zhe Ye who got the power of Aghito. On the deck, Zhe also turned into AgitΩ for the first time. AgitΩ was lost and fell into the sea. The water angel knew that the rest of the passengers would evolve into Agit Ω one day, but his task was to eliminate Agit Ω, so he spared everyone and warned them not to tell others the secret.

At the same time, the patrolman Glacier found this meteorological anomaly and sailed to the rescue alone, saving everyone by himself (at the same time, the Maritime Police Department was skeptical about the alarm because it had to meet important people, so it did not send patrol boats).

After the rescued passengers, except for a few cases of mental disorder, most people seem to be aroused and become ghosts. And these people with "power" naturally become the targets that nobody wants to kill. The passengers on board are: Michiko Mihura (9 episodes of death), Ryo's father (10 episodes of death), Sasahara Keiko (12 episodes of death), Tan Yaji (2/kloc-0 episodes of death), Kamiya Makoto (32 episodes of death) and Yoshihiko (3650). In addition to Konoha's power "awakening", Ji Ya, Zhencheng and Ke Yan all "awakened" their superpowers under the "inspiration" of (true) fragrance after contacting AgitΩ! Real name: Tomaki Tetsuya/Tetsu Sawaki Yeya. I am a student of the culinary institute. After learning that my sister committed suicide, I wanted to go to Tokyo to find my sister's boyfriend, so I boarded the Dawn. After being thrown into the sea, she was lucky enough to be killed by three female middle school students at a seaside in Seto Inland Sea. As he has nothing else on him to prove his identity, he has to be called "Shouichi Tsugami", the recipient of the envelope he carries with him. This is the origin of the name of the protagonist "Shouichi Tsugami". Waking up, Xiangyi temporarily stayed at Professor Mishima's house because of amnesia, and became the second diner and servant. Xiangyi has the ability to perceive the unknown and transform it into AgitΩ, but he has no idea how to have this ability. In the 43 rd sentence, the memory is completely restored. Although he began to object to being called Xiang Yi, no one wanted to change his mind.

The real person's name is Shouichi Tsugami, who is in contact with the God of Darkness in the play, that is, the boyfriend of Aimu Xuecai, the sister of Aimu Zhezhe. When Amy Shelley couldn't stand Agito's strength and tried to commit suicide by jumping off a building, Shouichi Tsugami stopped Shelley and finally let go at Shelley's pleading. Then Jin Shang Xiang Yicheng killed the first Agitω Ω human. In fact, he has died once, but it was dark. However, when Xiangyi betrayed the Black God and Tetsu Sawaki was about to be killed in the battle with Unknown, Shouichi Tsugami deceived the forces of darkness and made AgitΩ' s mechanical tornado have gliding mode, which enabled AgitΩ to successfully defeat Unknown. In later stories, Shouichi Tsugami helped AgitΩ many times, twice brought Gilles back to life (one died and the other was seriously injured and dying), which accelerated the evolution of ghosts and said, "My hands are used to protect mankind ...". In the last episode, Shouichi Tsugami, whose life was exhausted, bet on the power of darkness, and successfully stopped the idea of the Black God destroying mankind.
