This is the name of a humanoid monster in the legends and folklore of Japan. The Kudan is described as having the body and legs of a gigantic bull with three eyes along each side and a row of horns protruding from its spine. It has the head of a human. It was regarded as a beast that could never deceive and always told the truth.
Devil Summoner: Raidou Kuzunoha vs. The Soulless ArmyEdit
Kudan is a rare random enemy. In order to fuse Kudan, Raidou must defeat one in battle in order to claim the key item she drops, the Prophetic Book. Kudan, however, cycles weaknesses, has a large pool of HP, knows Diarahan, and will often try to escape rather than allow itself to be defeated. The Astral Burst combination attack is a virtual necessity to defeat her.
When you encounter Kudan, she says the following at the start of the battle;
"I can see it... The Capital burning in flames... The citizens fleeing in terror... A monster ravaging the city... It is your fated destiny... Escape is impossible. Prepare yourself."
However, after reaching certain progression points, she will instead say the following at the start of a random encounter battle;
"I can see it... A new Capital shall arise from the flames of the old... The indomnitable hearts of the people shall carve a new destiny."
Devil Summoner 2: Raidou Kuzunoha vs. King AbaddonEdit
"A cow with the face of a human that can speak human languages. It's born from other cows. It's said to be a terrible omen; it leaves a prophecy certain to come true, then dies."
The rumor to make Kudan appear can be obtained from Yasuo Inoe in the Bomb Shelter. Kudan can be found in the sixth area and drops Kudan's Head, which can be given to Yasuo for a Mutation Gear, Syncronize Gear, and Adjustment Gear.
