These randomly picked Up-Front Agency official photos show us clearly how kawaii Chii can be. Photos are from 2006 to 2009 in chronological order.
In last two photos Chii is dressed in black blazer & skirt set which are made of reprocessed polyester from plastic bottles. They are made of 25% recycled material. How I happen to know this? Because when it was Chii’s turn to be a sensei in Yorosen! TV serie she teached her students ecology and was wearing this outfit.
