Regrets became evident on Reina’s face after he had killed his enemy, Gen Yamashita, a young scientist who created the zombie virus that spread across Japan. He knows that he is the one who causes the death of his parents, but he soon realizes that vengeance is not the way to go. Instead, he became a monster like Gen, and he was devastated by it.
  Now, he decided to save Gen from his death, and after that, he became depressed and blamed himself for making the virus outbreak worse. It seems that he would be a broken person full of regrets.
  But, he will not last long in his painful depression. Gen came and reconciled with him, renewing their wills to live life again. Now they are racing against the clock to reverse Gen’s mistakes that wreak havoc across Japan. They will not do that huge and seemingly impossible mission themselves. Two of Gen’s subordinates, Arashi Hoshikawa and Nato Hokawa, and a pair of twin young women, Mara and Martha Buenavista, will accompany them in their mission, alongside Gen’s organization. Will this be a golden ticket for both Gen and Reina to a better life and future?

 A few days passed by, and Reina's act of self-denial became more and more extreme. Reina began to take long night shifts patrolling the headquarters' grounds because he had nightmares of his guilt and PTSD. He also made batches of his serum during most of the day to fuel his self-denial and self-sacrifice.


 Gen and others became worried for Reina's physical and mental well-being despite Reina eating well. But Gen can't really do much because he was preoccupied with his research for the cure to the zombie virus.
