Soak frog legs in milk for 1 hour, turning every 15 minutes.
Remove from milk and salt and pepper them lightly, and coat them in flour.
In a skillet bring the butter to a sizzle and add frog legs.
Sauté legs uncovered until they're golden brown on both sides (turning as needed).
Because it's all over the place, MC would still lose against a random mook, the battles are short, the romance is short, and it's at 5 volumes and two years!! with barely any plot progress. And then of course the Nagi subplot.
