"Wow - it's so good!" - Rin Tsuchimi
In the anime, Nerine goes a little overboard and makes a huge box-shaped egg. I reduced the portions here, so that you don't end up with an overwhelming amount of omelet to eat. Also, it's fine to use a regular frying pan if you don't have a special rectangular one.
Instead of mirin, you can use 1 tablespoon sake + 2 additional teaspoons sugar. For fancier omelets, you can add tuna to the egg before rolling and drizzle with soy sauce.
