Ep 1. Please Let Me Call You Big Sister!

Please Let Me Call You Big Sister! is the first episode of Gunbuster 2: Diebuster season 1. Set in the distant future, this sci-fi anime follows the story of Nono, a young girl with dreams of becoming a space pilot.

The episode begins with Nono racing through the streets of her boring small town, daydreaming about the stars and her idol, "Topless" Lal'C Melk Mark. Topless is an elite group of pilots that protect humanity from dangerous space monsters known as the "Space Monsters." Nono aspires to join their ranks and make a difference in the world.

Nono's world suddenly changes when she encounters a group of rowdy space pilots from the space battleship Exelion. Excited and full of enthusiasm, Nono mistakes their ship for a Space Monster and joyfully jumps onboard, ready to join the fight. However, her innocent mistake leads to chaos and confusion among the crew.

Soon, they discover that Nono is not a seasoned pilot. She is just an ordinary girl with big dreams and an even bigger heart. Despite her lack of experience, Nono is determined to prove herself and become a valuable member of the crew. With her unyielding spirit, she convinces the reluctant crew members to let her stay as their mascot.

As Nono settles into her new role, she quickly learns about the hierarchical system within the ship. She meets the stern chief mechanic, Nicola Vacheron, who enforces the rules and ensures the functionality of the ship. Nicola is initially skeptical of Nono's abilities but gradually warms up to her enthusiasm and ambition.

Meanwhile, Nono idolizes Lal'C, the legendary pilot whose bravery and skill saved humanity from annihilation in the first "Gunbuster" series. She yearns to be like Lal'C, often admiring posters and collectibles featuring her idol. Nono's admiration for Lal'C strengthens her determination to become a Topless pilot and protect the Earth.

The episode takes an emotional turn when Nono is caught in a precarious situation during a simultaneous practice sortie. Despite the danger, Nono refuses to give up and manages to overcome her fear with sheer determination, earning her the respect and support of her crewmates.

As the episode comes to a close, Nono faces a significant obstacle on her journey to becoming a Topless pilot. She must pass a rigorous training program called the "Two Topless Exam," where only individuals with immense ability and resilience can succeed. With her unwavering determination and the encouragement of her newfound friends, Nono prepares herself for the challenges that lie ahead.

Please Let Me Call You Big Sister! sets the foundation for Gunbuster 2: Diebuster, introducing us to the endearing protagonist Nono and the thrilling world of space battles. Filled with hope, ambition, and a touch of comedy, this episode showcases the beginning of Nono's epic journey to become a Topless pilot and defend humanity against the Space Monsters.
