Raw Powers

Raw Powers can be "equipped" by making them your Favorite Sushi giving you boosts at certain points in a battle.

Secret Scroll entry
"When you eat a great deal of one type of sushi in a certain time, that sushi's raw power dwells within you. If you declare that sushi as your Favorite on the Striker Specs screen, you can harness that raw power during battle!"

"Once you do that, the raw power will kick in automatically by fulfilling certain conditions! Try experimenting with how different kinds of raw power work together with sushi sprite skills!"
