While Ultraviolet hadn't been expecting an attack, he was quick to react and block. Reactions like this were something he was used to, as a reaper.... hardly every soul he dealt with was calm. Death could be just as frightening as it could be peaceful, so Ultraviolet had learned to approach with gentleness... his smile, while strained from all the stress of the day, was there and warm as he backed away from Yamii.
But Giratina was not so gentle, and very much was not pleased.
The look on his face quieted Ultraviolet. His tail wrapped around his legs as he looked back at Yamii. "Father-"
"This creature has attacked you, in my realm, right in front of me," Giratina said, voice a low snarl.
"He is frightened of me. He has been ever since he appeared in my world." The glowing eyes of the god narrowed on Yamii. "I have not threatened you. I know not why you fear me, fear my kind. This information is yours. However." He bared his teeth. "If this fear is so intense that it drives you to violence towards my son, you should not be here, voidling. You are not welcome here." He stepped forward, standing tall, his voice an indisputable order. This was the King of the Distortion World, after all.
"Leave this place before my patience grows thinner."
