Translation: “Sneak-sneak-sneak! Sneak-sneak-sneak! Oh, my lord! I've been waiting for you! I'm looking forward to today! Nin nin!”

Apparently “sasasa” is just some onomatopoeia she says when she’s running from place to place.

Edit: Never mind, it’s manga SFX for sneaking. I’ve edited my comment to reflect that.

It's SFX for "sneaking" or "walking quietly", she's making the sound to convey that she's sneaking.

So it’s basically her Litany of Stealth, then? Sounds legit.

a sound effect for being quiet, especially when reading manga is kinda ironic.
