Hana to Cure Yell
Hana holds her PreHeart in its phone mode and inserts her Mirai Crystal onto the device while saying "Mirai Crystal!". She then flips the device into its heart mode as the screen flashes on with a white heart that emits white light as she says "Heart Kiratto!". Covered in a pink glow, she presses the red heart on the PreHeart while saying "Hagyuu~" until pink hearts fly out and create her dress, her pompoms, socks and shoes. She presses the red heart again while saying "Gyuu~" to change her hair length and color as well as adding her hair accessories. She presses the red heart for the final time to allow her earrings and tiara to appear. She places her PreHeart in its carry bag on her waist and says her introduction phrase while jumping high into the sky before landing on the ground to say her name as she poses.
