《 SIRIUS 》

His identity is as mysterious as his powers. He was the one who opened the first ride at Starr Park, but he was unjustly kicked out and banned from returning. Now he's back... and he's out for REVENGE!

The name Sirius comes from the star of the same name, which is one of the brightest stars.
Sirius is the main antagonist of the entire Starr Park.

Sirius summons shadow copies of fighters that have similar characteristics to the original, controls them, and gives them orders.

Before Starr Park existed, there was an island inhabited by people. However, due to unknown circumstances, people began disappearing, leading to the island being abandoned. Sometime later, Starr Circus opened there, where Sirius performed a shadow show. It was extremely popular, and people from all over the world flocked to the island to see his performance. As new performers began arriving on the island and the Circus became Starr Park, Sirius's show became less popular, and his pride and thirst for an audience grew, forcing him to make his performances increasingly dangerous. Visitors noticed that their shadows didn't appear for several hours after the show ended. Sirius became increasingly reckless, becoming consumed by his own shadow and stealing shadows from others. Things got so bad that park management arrested him and banned him from the park outside of performances. That night, Sirius's tent burned down, and he vanished without a trace. Eyewitnesses to the fire reported that despite the lack of light, shadows continued to dance on the walls and under the dome of the tent.

He wears a golden mask. On his shoulders is a purple robe with small white sparkles, reminiscent of stars in the night sky. He has gloves on his hands. He carries a cane with a crescent moon on top.
