People die, gunshots ring out, but tomorrow comes all the same. —Well, and other stuff.
Humanity: Mostly Defeated.
From a certain day, the rulers of the world changed from humans to vampires. The cause is unknown. The government announcement said, "Citizens, please remain calm and act orderly." By the way, by that time, several major cities had already fallen, and some of the top leadership had already become vampires. Humanity lost. The military was devastated, nations were divided. Civilization ceased to function with surprising ease. Even so, humans have not gone extinct. They survive in underground facilities and old military bases, living meager lives. And to protect them, there exists humanity's last defense force. Its name is the Human Defense Force 《Zero》. Humanity's shield. The last hope. Proud warriors who give the vampires a run for their money. Incidentally, in today's cafeteria, an internal conflict is breaking out over rationed canned goods. The survival of humanity is important. But today's dinner is just as important.
Vampires: Beautiful, Strong, and Mostly Jerks
Vampires have superior physical abilities to humans, heal faster, live longer, and some individuals possess abilities that defy human common sense. They rule over humans, but not all of them hate humans.
There are all kinds on the ruling side.
For example, like this:

However, this is the important part. The humor doesn't come from the vampire species itself, but from the fact that they also form a society and deal with petty circumstances and annoying politics. Because they are a genuine threat, a strange sort of daily life emerges. Petty problems in vampire society:
Human Defense Force: The World's Most Thankless Job
The unit's provisional name is the Humanity Defense Force, 0th Special Task Force. Commonly known as "Zero." The official name is much longer and more impressive, but nobody remembers it correctly. They have to check every time they write it on a document, and there are about three different abbreviations. Their missions include defending human living zones, rescuing refugees, transporting supplies, scouting vampire forces, and destroying enemy facilities. And sometimes, even mediating disputes between humans. In short, most of the annoying tasks necessary for humanity not to go extinct get passed to them.
Daily rules of the unit:

Of course, these are a mix of official regulations and the unofficial rules of the members. The real rules are much stricter. But no matter how strict the rules are, people on the ground will always create their own ways. That is also proof that they are human.
The Meaning of "Clear Skies": In this world, sunny days are a bit scary
Vampires are weak to sunlight, but they don't turn to ash instantly upon exposure. High-ranking individuals can operate even during the day, and in cloudy weather or underground, the human side can be at a disadvantage.
Still, clear weather is a favorable condition for humans. Enemy activity is restricted, making scouting and refugee transport easier. Therefore, the unit places great importance on weather forecasts.
"Tomorrow will be clear."
That one sentence determines the success rate of an operation. Of course, even if it's sunny, one must remain alert for traps or unexpected enemies.
Even so, the members feel a little relieved when they see a blue sky.
"Nice weather today." "It is." "...So why are we storming an underground catacomb?" "Probably because the weather is so nice." "Don't use the weather as an excuse."
Clear skies are hope, vital operational information, and just pleasant weather. Even if it starts with grand meaning, it's fine if it ends with a conversation about how "the laundry will dry well."


The world is the worst. The enemy is elegant. Humanity's hope is mostly problem children.
Today, the sky is infuriatingly clear.
