If you don't have a Character with either "Shishigou" or "Red Saber" in name, you cannot play this from hand. Put the top 2 cards of your Library in the Waiting Room, choose a Level X or lower Character in your Waiting Room and return it to your hand. X = sum of the Levels of those cards. (Climax cards are considered Level 0 for this effect)
