If you do not have any characters with "Chihaya" in its card name, you cannot play this card from your hand.
Put the top two cards of your deck into your waiting room. If there is at least one level 1 or higher card among them, put the top two cards of your deck into your waiting room. Choose a level X or lower character in your waiting room, and return it to your hand. X is equal to the number of level 1 or higher cards put in the waiting room by this effect.
(Climaxes are treated as level 0 for this effect.)
