Miyazaki Sakura comes from a family with a long tradition of swordsmanship and has been exceptionally gifted since childhood. Once grown, she unexpectedly became a...
Chef.
Her good-for-nothing deskmate immediately objected: "That's completely unexpected! How is that not unexpected? Everything about you, from head to toe, is unexpected!"
But that wasn't important.
Following the Way through cooking was also a form of training.
Her heart's desire was the source of her strength.
Her deskmate: "How can your heart become a source of strength?! Show some respect for physics!"
Note: Later, her deskmate's resolve became a source of strength, and from then on he couldn't hold his head up around Miyazaki Sakura.

Of all the world's cuisines, Miyazaki Sakura loves sushi best.
Rice is the foundation of sushi, and fish is its essence.
So she has to learn to fish.
Her deskmate is still making a fuss: "You just want to skip class, don't you? How come fishing counts as your social studies project?!"
Miyazaki Sakura thinks he's jealous, and nearly gets beaten up by her deskmate's devoted supporters.
But her fishing is nothing like anyone else's.
Every night before bed, she can choose to sacrifice that night's sleep and her first two classes the next morning to dive into the Blue Hole.
Strap on a speargun, sling a fishing hook over her shoulder, and off she goes!

With the freshest ingredients around, the Miyazaki family soon opens the most renowned sushi restaurant in Namimori.
But lately, Miyazaki Sakura, who always manages to get the freshest ingredients, has discovered that the Blue Hole she visits every day is an extraordinary place.
Catching a sixgill shark is one thing, but why is there a white-haired guy who calls himself a shark?
Why is there also a violent shark boss?
And why are there people from the future and the past?
Hey, no matter how you look at it, putting marshmallows on rice is just too destructive... Don't think I won't use this kitchen knife!
Punish them, punish them all!
The good-for-nothing deskmate is always fleeing to Miyazaki Sushi after a big battle. He puts on a mysterious look of ownership and says, "Heh heh, this is the safest hideout in Namimori!"
Miyazaki will never let anyone disturb her customers while they're eating!

* Unless something unexpected happens, this will be Katekyo Hitman Reborn! only, though other worlds might pop up from time to time, but not many!
