I give you: The literal rectangle. Recilia. lol she is about the same personality as dee but way more spontaneous also is FRIENDS with them lo also makes geometry puns literally any chance she can for example [puns are captialized]: "Boom. Caught ya at a tough ANGLE? Just wanted to SQUARE things away, before I got PROOF of your demise. I really wanted to get things going on the RIGHT track before I end up cutting CORNERS for the SEGMENT. Is that too much to ask...? Maybe I shouldn't have gone off on a TANGENT and just gone STRAIGHT to the POINT."
Dee is just for height comparison lol
