No worries, you are spot on! The pi is redundant.
I used to have it as
sewi pi tomo kon // sewi pi tomo ni
And then did not use either, figured it would be fine without clarifier – but left the pi. I remember thinking about it, and still leaving it in. My mistake! Should update it, good catch!
And thanks for the encouragement! I'm really excited by this idea, looking to keep honing it and expanding on it beyond this first encounter.
Thank you for the feedback and comment!
