The Superstar Sunglasses (星形”PEACE”サングラス Hoshigata "PEACE" Sangurasu , lit. "Star-Shaped 'PEACE' Sunglasses") is an item found in Corpse Party.
As the player is controlling Satoshi Mochida and Naomi Nakashima, they can enter the boys bathroom and find the sunglasses, broken, inside a sink, albeit it is not possible to obtain it as an item yet.
However upon showing these glasses to Shimoda, he let's out a disgusted sigh as it would be very difficult for anyone to look good while wearing them. They are discarded from that point onwards.
