Mirai Crystals

Mirai Crystals (ミライクリスタル) are small, collectible, crystals that contain Tomorrow Powerer and are the physical form of the power. They appear in HUGtto! Pretty Cure and are used to transform and use attacks. Mirai Crystals are also used by the Pretty Cure to care for Hugtan.

In the anime
When inserted into the PreHeart, they can be used for the Pretty Cure to transform and use their attacks. The Cures' Crystals can also be inserted onto a spoon to feed Hugtan their Tomorrow Powerer. In episode 3 it is revealed that eight Crystals are needed to make time start moving again for Hugtan. From episode 6 on, the girls also use the Crystals with the Mirai Pad to change into various job outfits.

As toys
When set into the PreHeart toy, the Mirai Crystals each unlock different voice samples. Used with the Mirai Pad, they unlock new job outfits. It is not known yet if different Crystals have different effects when used with the Cupoon and Hugtan doll.

Appearance
The transformation Mirai Crystals are small and heart-shaped. They have tiara-like tops and have three gold bars leading into an inner crystal in some shape (i.e. flower for Cure Yell's, Circle for Cure Ange's, and Star for Cure Etoile). There is gold trimming around the heart. Each, however, appear to have decor on them that depict the Pretty Cure's motifs.

The second Mirai Crystals the Cures receive are each shaped as their respective motifs (i.e. a flower for Cure Yell's, a wing for Cure Ange's, and a star for Cure Etoile) and are deeper in color compared to their first ones. The center crystal is the same as their first ones as well.
