AMAIM Warrior on the Verge of a Breakthrough AMAIM, also known as Ghost, murdered Tezuko’s father in Episode 10, which is revealed in the following scene: Tezuko begins to question whether he has been on the wrong path all along. He comes to the realisation that his father’s life was in Ghost’s hands as a result of his foolish behaviour.
Despite the fact that his father was the one who went out without his AMAIM and was slain by Ghost, he continues to believe that he is to blame for his father’s death. The novel AMAIM Warrior at the Borderline depicts the never-ending clashes between the Japanese resistance and the Japanese armed troops.
On the day of the war, Tezuko recalls everything that has transpired and discovers that they have even failed to catch Ghost, who was present during the combat. He is perplexed as to whether he is to blame. Tezuko, Shion, and Amou met with a man in the morning who informed them that they would be able to use the next truck to get to the headquarters.
They discuss the shopping providers, and Tezuko shares everything that he knows about the subject matter. The man in the suit comes and appears to recognise Tezuko, prompting Tezuko to deduce that the man is Yuu. They had to go to the park in order to celebrate their reunification.
As a result of Yuu’s outfit, Tezuko realises that he hasn’t recognised him, and Shion wonders if Yuu is Tezuko’s older brother. Amou, on the other hand, is well aware that Tezuko never brings up the subject of his brother with him. It is revealed by Kai that the man’s full name is Suenaga Yuusei and that he has previously stayed with his parents at Yataragasu.
Yuu’s parents, on the other hand, were killed during the war against the Asian troops. As a result of Tezuko’s father’s care for Yuu prior to his death, Tezuko considers Yuu to be his big brother. Yuu and Tezuko have known each other since childhood, and Tezuko refers to Yuu as his brother so that he will never feel lonely.
