Polyester and Polyurethane from the anime Panty & Stocking with Garterbelt are two angel brothers sent from Heaven to replace Panty and Stocking as the ghost hunters of Daten City. However they didn't expect human food to be so delicious and quickly fell in love with the cousine now spending most of their time eating growing  round guts in the process. They are egoistical and think highly of themselves but are also very lazy and gluttonous outside of work. Use a lot of  gen Alpha slang
