Ravenknightv is correct. Works for SuperStrike characters.

In short, dokkan awaken a 10/10 superstrike card using 7 awakening medals  to reach 10/15. Then dokkan awaken a 5/10 superstrike card using 7 awakening medals to reach 5/15. Train the 10/15 card with the 5/15 to reach 15/15. That means you need 7+7 awakening medals for 14x25 stamina.

There is a page exclusively dedicated to SuperStrike characters here, which you can reach by searching "superstrike" via the search box on top.

Additionally, after you reach the 15/15 card, you can choose to farm for the same card, so you can have a 10/10 UR, or a 1/10 UR, and/or a 1/10 SR/SSR. The latter is for the lower cost, specially for events that capped maximum cost at 100.
