This is meant as an alternative for the coins/pawns meant for the game. Print it (best on thick paper), cut it (same height for all chars, will be some leftovers), glue it and use a plastic stand or twisted clip to keep them up. These images were ripped from Yomi's PnP (low res). They usually correspond to one of the character's ability, like Thunderclap, Esper Dash, Pilebunker, etc.
