Though he is usually able to control it, Matsu is very hot tempered. He especially hates PKers, and does everything in his power to defend people from them, including going on regular patrols to find and stop PKers. His oath as a member of Moon Tree keeps him from attacking players except in self defense, but he has learned how to taunt PKers into making the first move, allowing him to defeat them without any repercussions. He is fiercely loyal to Zelkova and Sakaki and recently developed a rivalry with Haseo. 

The characters from previous .hack//G.U. Games and .hack//Roots receive an email from Ovan. He is requesting them to go to Hidden Forbidden Festival where is set up a mysterious summer festival. There they find an AIDA Chim Chim who wishes to peacefully co-exist with the other players of The World. It then transforms into the word "Returner", so they assume it to mean that Ovan will return to The World.
