The Wakunan Google Chromes

With no official mention of a mascot, due to a stage play booklet, Wakunan's mascot is jokingly believed to be Google Chrome.

History
On December 5, 2018, the Captain of Johzenji, Cardea, posted pictures of a booklet for one of the stage plays in #central-court. The message consisted of photos depicting Karasuno's mascot (a feather to represent crows), Johzenji's mascot (a temple), and Wakunan's. Unlike the other schools, Wakunan's photo of a circle made it unclear as to what their mascot is. User sinkroutine then suggested that Wakunan's mascot is Google Chrome due to it's similarity to Google Chrome's logo and the idea was adopted into the server.
