But the person who has always believed in light and hope is as great as the light. Finally, he awakened to the power of light! However, the gap in strength between the monster and him is too big! Fortunately, the system can travel through Ultraman's time and space! He learned physical skills in Leo's world and light in Ace's world. Showa, Heisei, and the New Generation all have his shadow!
