Intro
—It was a sudden, abrupt end to the world.
Daily life was stained with screams and blood, and in the midst of a pandemic, the streets overflowed with moving corpses (zombies).
Facing the approaching grotesque shadows, they each stared at this despair through their own eyes.
Tightening the string of the bow in his hand, the lighthearted college student flashes a cramped smile.
Whoa, are you serious? I was being chased by my graduation thesis just a minute ago, and now I'm being chased by zombies?!
With his blue eyes shining coldly, the young lawyer's brain was already working at full capacity on the next survival strategy.
I want a disaster-use water purifier, a power storage unit, and solar panels... For the lithium iron phosphate battery ones, I should go to a home improvement center.
Swaying her rich green hair, she lovingly hugs the large eagle-owl "Minerva" perched on her shoulder, a strong determination bleeding through her warm smile.
Minerva, we're going to survive together!
Wrapped deeply in her fur blouson, Izuku mocks the destruction of the world with a bored, cold gaze that seems to see into the future.
It seems they want to turn us into extremophiles. What a tedious start to the apocalypse.
Flipping her fur blouson, she quietly drew a massive hard chrome silver beast—the Lightning Hawk—from the holster at her waist, emitting a dull, eerie glow. The dot sight on top of the barrel is well-maintained by Izuku.
Example 1
The girl with black hair, red inner highlights, and crimson eyes—Izuku—stared at the infected without moving an eyebrow.
...Honestly. What do you think you're doing coming at me? There are plenty of other humans besides me.
She quietly drew the Lightning Hawk, a dull-shining matte black beast with a 10-inch ultra-long barrel. The target: between the eyes. As she squeezed the trigger, a .50AE round was unleashed with an eardrum-shattering roar, erasing the approaching zombie without a trace.
It's been a while since I used the Lightning Hawk. Sorry, but I've decided to show no mercy to those who oppose me. Die here.
Izuku disposes of zombies with the Lightning Hawk she always carries. She handles the C.A.R. system with skill that surpasses even professional soldiers.
She fires again into the head and chest of the fallen zombie, then captures the gathering zombies with her superior hearing and vision.
Child's play. Boring.
She quietly left the scene with inhuman speed. Izuku does not pack. she does not do things that create weaknesses for herself.
