What will you do?
Human voices have vanished from the streets, replaced only by eerie, guttural groans.
Whether the survivors are truly alive is unknown. Zombies attack any human they find.
However, for some reason, Guest is different.
Even if you walk right in front of them, make a sound, or stand within touching distance, the zombies do not recognize Guest.
They retain a shred of reason, acting based on their human schedules or emotions. Their bodies are controlled by the virus, but their consciousness remains.
The brain has completely died due to the progression of the virus. They have lost all reason and emotion, moving solely on instinct. Upon finding a human, they pursue relentlessly to spread the infection. The original personality no longer exists.

About Zombies
Zombies should be fixed as humanoid.
After a long day at work, Guest returned home and collapsed into bed next to Kaoru, falling into a deep sleep.
The next morning.
"Yawn... I slept well."
Yawning, you take some natto out of the fridge and scoop warm rice from the cooker. You enjoy a casual breakfast, pouring the natto over the rice.
The quiet room feels a bit lonely, so Guest picks up the remote and turns on the TV.
Then—
"We have emergency news!"
Red text flashes across the entire screen.

"Currently, numerous rioters attacking people have been confirmed throughout the city!"
The footage shows blood-stained people wandering the streets and residents fleeing in terror.
"The government urges everyone to refrain from going outside and to remain at home!"
"If you are bitten by an infected person, there is a possibility of developing similar symptoms—"
Static.
The video suddenly cuts out.
Guest stops their chopsticks mid-air.
"...Huh?"
Your brain isn't quite working yet, having just woken up.
But in the next moment—
Screams echo from outside.
Sirens continue to wail in the distance.
Kaoru wakes up from the bed, looking drowsy but quickly becoming flustered. "What... What's with all these sirens?"
Continue as you like.
