Third person POV
[Flashback ended, back to the present]
After breakfast, Shu had a pit stop to the underground cages of the infected. There Nato was tearing up as he watched Hoka eating his breakfast meal with his red eyes and pale skin, plus slightly jerky movements as a zombie. It was emotional as usual, and Shu watched it as he handed over food for the other caged zombies. After that, by 8:21 a.m., he went on patrol duty with Gen, Mara, Ichiro, Martha, and a squad under Nato to look out for any zombies. Ichiro went ahead to clear the way through the ruined city. Shu felt much better because of last night, and the Buenavista twins saw that and wondered what made him happy now.
"Um…Shu-kun…" Mara asked.
Shu then looked at her. "Sí, what is it?"
"Are you okay now?" Martha asked while being worried for him.
"Ah, yes, sí, I am, why?"
"You were strangely okay," one of Nato's squad members responded. "Did something happen last night?"
Not wanting to leak the fact that they did a strangely violent treatment last night, Shu and Gen lied that they did a therapy session with Dr. Ken to treat their mental illnesses last night. Luckily, they bought it and didn't ask any more questions, much to the relief of Shu and Gen.
And then, Ichiro, who was on the top of a derelict truck, spotted something from a distance ahead of them and signaled to Shu and the others that whoever was coming their direction will meet them soon. "Oh, someone?" Gen asked.
Ichiro then nodded before pointing at the two silhouettes coming towards them.
In response, Shu and the others looked at that. Meanwhile, the two silhouettes are actually Tashio and Kashi, and upon encountering Gen and his men through his red-infected eyes, Tashio went on revenge mode and pointed his assault rifle at them, opening fire at them while screaming aggressively.
"Get down!" Gen screamed to Shu and the others upon being alerted of the bullets speeding towards him and others.
Kashi was alerted by his father's actions and tried to calm things down, while Ichiro came down and tried to calm things down with Tashio without fighting him off.
Gen, Shu, and the others took cover on an overturned city bus, and Nato and his squad responded by trying to be in peace with Tashio.
But…
"I'll kill all of you!" Tashio shouted, before reloading his assault rifle with a spare magazine from his tactical vest and continuing to fire at Nato's squad in aggression for revenge.
"Calm down, Dad!" Kashi begged him in response, trying hard to stop the two sides from fighting.
"Tashio, stop this!" one of the YKY's soldiers, a rocketeer named Ran Takemikazuchi, pleaded while switching his RGP-40 grenade launcher for his standard pistol. "We're sorry!"
Tashio wouldn't listen to Ran.
But then, Gen recognized Tashio by his voice and said, "Tashio-san…" Glaring at Gen through his bloody gas mask, Tashio pointed his gun at him. "Yes, it's me, Gen-san. I will never forgive you for what you have done to me."
"Dad, please, no!" Kashi kept on begging.
