He infiltrates the home of the Hinata family in an attempt to establish a headquarters that he and his troops could use to prepare for world domination... but earthlings Fuyuki and Natsumi Hinata are too much for him to handle! Natsumi instinctively calls them out of hiding, leaving the hapless sergeant no option but to reveal his secret identity. The two siblings soon welcome the sergeant to their home, all thanks to Fuyuki’s generos—err... curiosity. The Sergeant has successfully infiltrated his first target area! Or has he? Join Keroro Gunsou in his dastardly attempt to take over the world!

Ichirou Inuyashiki is a 58-year-old family man who is going through a difficult time in his life. Though his frequent back problems are painful, nothing hurts quite as much as the indifference and distaste that his wife and children have for him. Despite this, Ichirou still manages to find solace in Hanako, an abandoned Shiba Inu that he adopts into his home. However, his life takes a turn for the worse when a follow-up physical examination reveals that Ichirou has stomach cancer and only three months to live; though he tries to be strong, his family's disinterest causes an emotional breakdown. Running off into a nearby field, Ichirou embraces his dog and weeps—until he notices a strange figure standing before him. Suddenly, a bright light appears and Ichirou is enveloped by smoke and dust. When he comes to, he discovers something is amiss—he has been reborn as a mechanized weapon wearing the skin of his former self. Though initially shocked, the compassionate Ichirou immediately uses his newfound powers to save a life, an act of kindness that fills him with happiness and newfound hope. However, the origins of these strange powers remain unclear. Who was the mysterious figure at the site of the explosion, and are they as kind as Ichirou when it comes to using this dangerous gift?

It's her first day at a new school, and the cheerful Hana Nono is ready to make a fresh start, dreaming of becoming mature and reliable—a far cry from her usual childish self. Although she makes a disastrous first impression, Hana soon befriends two of her classmates: the gentle and studious class representative Saaya Yakushiji, and a cool and mysterious girl Homare Kagayaki. That night, a magical baby falls from the sky right onto Hana's balcony. She is immediately smitten with her and names her Hug-tan. Alongside Hug-tan is a snarky talking hamster, Hariham Harry, who mutters that Hana "isn't the one" before vanishing with the baby. The next day, Hana believes the encounter to be a dream, until people all over the city begin collapsing and a giant monster appears, feeding on their energy. As Hana escapes, she spots Hug-tan and Harry under attack. Making a stand to protect them, she and Hug-tan suddenly both glow with energy and a heart-shaped gem forms. With the crystal's power, Hana transforms into a hero called "Cure Yell" and defeats the monster. Surprised at Hana's power, Harry explains that he and Hug-tan came from a future frozen in time by the Criasu Corporation, the same organization that created the monster. Only the Future Crystals, manifestations of one's hopes and dreams, and the Precure they create have a chance at defeating Criasu and saving the future! [Written by MAL Rewrite]
