Henshin Touch Phone PuriHeart (main unit) + 4 Mirai Crystal set. No instruction manual included. Two modes: You can transform from the smartphone-shaped "Denwa Mode" to the heart-shaped "Heart Mode." • Transformation/Attack Play: By setting the included "Mirai Crystal" and touching the heart mark on the screen, you can enjoy playing with character transformations and attacks. • Other functions: It also includes phone play with the character "Hugtan" from the show, mini-games, and melody play. I have checked the operation with batteries, and there were no particular problems. The part circled in red in the photos is slightly discolored. Please understand that this is a used item before considering a purchase.
