Taken from Tsubasa Chronicle and Cardcaptor Sakura:
I noticed that Yukito’s magic circle on Tsubasa Chronicle is somewhat similar to the original magic circles of Sakura. It’s kinda nice because in the TRC manga it was only minimally drawn so some people may not notice.
And there’s Mokona’s magic circle, which I’m not sure if it’s an original, or maybe from Magic Knight Rayearth. Sorry I didn’t watch Rayearth.
