The Dawn of Yami (referred to as Force of Yami during Tensai Special Jounin season and is known as the Dawn of Darkness when translated) is a group created by Vadar. Their main goal is to take over the village and recreating the village as his dream village.
After the Chunin Campaign when Kojima attacked the Fire Village, Vadar was learning a skill by his clan called Kinjutsu: Spirit Integration and then he left the village, seeking revenge against Yudai and the village.
Vadar is an S-rank ninja who is the master mind behind the war in the Special Jounin Campaign. He could be the grandson or grandnephew of Chiyo but he is the cousin of Kage Yudai, Ken, Aiko, and step-cousin of Anaki but he really hates Yudai. He can produce large chakra attacks and Time-Space Ninjutsu. He first appears in Stage 1-2: Unpredicted Attack of the Special Jounin Campaign as the master of Genan.
A fire ninjutsu and kenjutsu user. After the defeat of Genan, Akazosu attacks the main character and brings along an Earth-element Undead Puppet and a Wind-element Undead Puppet. Compared to Genan, Akazosu is much stronger as he calls Genan a loser.
The Ninja Panda specializes in Taijutsu and fights brutally. Due to his big size, he hold a great strength. He first appears in Stage 5-2 of the Special Jounin Campaign as the Ninja Panda was lured into a trap created by Mori Naruhisa.
The Bull Mask is a masked beast summoned by Vadar from using Kinjutsu: Spirit Integration. The Bull Mask has a crazy personality but it is a powerful beast. The Bull Mask first appears in Stage 6-1: The Released Beast of the Special Jounin Campaign.
