When you look up at the sky, what do you see? A blue sky? Freedom? A hopeful future? The people of Tokyo see none of these. Instead, an ominous alien mothership looms overhead, engulfing the city skyscape. Three years ago, they came. The arrival of the "Invaders" sparked the greatest war humanity had ever faced—one that threatened to end the world. The Japanese government scrambled to fight the Invaders. Weapons were mass-produced, sparking controversy and pacifist movements. That day, everything changed. And yet, nothing has changed. Kadode Koyama and Ouran Nakagawa live their final days like they always have: going to school, playing with friends, and doing what any carefree high school girl would do. As they grow up, they come to learn what it truly means to be an adult, in a world where adults seem to be demons who only deceive and destroy. They come to learn the real threat to humanity is not the Invaders, but humanity itself.

Smart, refined, and strikingly gorgeous, half-Russian half-Japanese Alisa Mikhailovna Kujou is considered the idol of her school. With her long silver hair, mesmerizing blue eyes, and exceptionally fair skin, she has captured the hearts of countless male students while being highly admired by all others. Even so, due to her seemingly unapproachable persona, everyone remains wary around the near-flawless girl. One of the few exceptions is Alisa's benchmate Masachika Kuze, a relatively average boy who spends his days watching anime and playing gacha games. Despite his nonchalant demeanor, Masachika is the sole student to receive Alisa's attention. Unable to be fully honest, Alisa is frequently harsh on Masachika and only expresses her affection in Russian. Unbeknownst to her, however, Masachika actually understands the language yet simply pretends otherwise for his own amusement. As the odd pair continues to exchange witty and playful remarks, their relationship gradually grows more romantic and delightful—and Alisa might finally learn to freely convey her true feelings.

Using the seaside terrain to their advantage, the people there have adopted golfing as their hobby. To add to his surprise, Kazuyoshi meets a young girl named Tonbo Ooi, who has been playing golf using only a 3-iron—a notoriously difficult-to-use club. As the former pro gets more involved with Tonbo and witnesses her seemingly impossible shots, he begins to see golf in a whole new light, rediscovering how fun the sport can actually be.
