Decrypt the Encrypted String

You are given an encrypted string that contains lowercase alphabetical characters along with some special separator characters. The special characters are defined as ( { '#', '$', '&', '@', '!' \} \). Your task is to remove these separators from the string while maintaining the order of the remaining characters. The decrypted string should only contain the original alphabetical characters. For example, given the input a#b$c@d&e!f, the output should be abcdef.
