During one meeting with a clan of ninjas, it has been noticed that more ninjas have turned up to the meeting than usual. The ninjas realised that these infiltrators must be the enemy of the ninjas (the pirates). Each person dressed as a ninja at the meeting made a statement. The cunning ninjas lied about their fellow ninjas in order to remain secret and told the truth about the pirates. The pirates tried to mock the cunningness by lying about the pirates and telling the truth about the ninjas. From the following statements, can you identify the ninjas and pirates?

Ninja A: Ninja B is a ninja
Ninja B: Ninja C belongs to Ninja A's group
Ninja C: Ninja C doesn't belong to Ninja F's group
Ninja D: Ninja A belongs to Ninja B's group
Ninja E: Ninja B belongs to Ninja C's group
Ninja F: Ninja E belongs to Ninja A's group

Remember, the ninjas and pirates will lie about individual ninjas or pirates, not groups of ninjas or pirates.
