Series by 石渡治

Growing up in Tokyo's lively downtown, Magami Massugu is a spirited troublemaker with big dreams and a heart full of passion. Inspired by his father's work on Japan's H-II rocket, Massugu sets his sights on the stars, determined to become an astronaut. From the bustling streets of his neighborhood to the awe-inspiring launch site at Tanegashima, his journey is fueled by ambition, friendship, and an unyielding desire to reach for the impossible. But chasing such a lofty goal comes with challenges, as Massugu must navigate school, family, and the complexities of growing up while keeping his dream alive.

Hino Tamao is a brash, big-hearted teen who arrives in Shonan searching for his deadbeat detective dad, earning himself the nickname "Fireball Boy" for his wild spirit. At the beach, he meets Momoko, a spunky girl who drags him into a whirlwind of high school chaos at Madaruya High. With guts to spare but little fighting skill, Tamao unleashes his secret weapon—superhuman “Hungry Power” that kicks in when his stomach growls—turning him into a force to be reckoned with.
