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?

Hearts and Redemption in a Zombie Outbreak

In his room, while Gen was busy researching for the cure, Reina was looking at the small, non-glossy, paper photo. That photo was a photo of himself as a young kid. Reina felt so sad, thinking of his past self as an actual person.

"I'm sorry…" he uttered in a low voice while staring at it, "…I felt I had failed you. Sorry for killing you…"

He felt that by attempting to kill Gen for killing his parents, Reina felt as if he had betrayed and killed his past self metaphorically.

So, Reina stood up and placed his photo on an empty shelf on a bookshelf, before placing two small, white, wax candles in front of it.

He then lit flames on the two candles with a lighter.

The distance was far enough so the photo would not get burned by the two candles' flames.

After that, Reina stood in front of it in mourning, crying and shedding tears of sadness, regret, and grief.

Although the medicine and therapy worked, Reina's bad memories and PTSD returned and wreaked havoc in his mind and well-being like a tsunami, and this prompted him to introduce harsh punishments to himself to counteract the guilt and PTSD.
