Ultraman Arc + 3 Special

Synopsis:
16 years ago, kaiju attacks occurred all across the globe and were suppressed by the Global Defense Force or GDF. This incident, dubbed as "K-Day" changed the world forever. At Hoshimoto City, a giant horn-like object is stuck on the ground as a reminder to that incident known as the "Monohorn", the horn of the galactic beast Monogelos as the GDF kept on dealing with kaiju attacks on a daily basis. To prevent disasters caused by these attacks, the GDF opened a special organization named SKIP or Scientific Kaiju Investigation and Prevention center to works closely with the community in scientific investigations and evacuation guidance to prevent the occurrence and aggravation of kaiju disasters. SKIP has also been investigating the Monohorn which appeared on K-Day.
Yuma Hize is one of the people who survived an attack with Monogelos but his parents died during the attack. After that experience, he pursue a career on kaiju biology research, and despite his traumatic past, he has not lost his "imagination" to dream. As a rookie investigator, Yuma joined SKIP and was assigned to the Hoshimoto City Branch. But when a new kaiju attacked the city and Yuma desperate to help the people in need, Rution, the being of light that he once saw as a child came to his aid and told him to unleash his imagination. With both of their powers, Yuma transforms into a new giant of light: Ultraman Arc in to protect everyone from kaiju attacks threatening the city.
