Hise Yuma works for SKIP, the Scientific Investigation Team for Disaster Prevention. A monster disaster took his parents when he was a child. As the sole survivor, he has always dreamed of protecting others, and even drew a hero from his imagination when he was young.
Lutian, a messenger of light from a distant galaxy, came to Earth to prevent a disaster caused by an unstable star, but was gravely injured and crashed there. Thanks to Yuma's powerful imagination, the two became one and transformed into the Giant of Light, Ultraman Arc. Arc's appearance was exactly like the hero Yuma had drawn as a child. As Yuma investigates the monsters' strange mutations, he uses the power of his imagination to overcome crises caused by monsters and forces from the universe.
I finally found a book about Akko with many chapters and good writing. To be honest, reading 26 episodes of the original book is not enough.
