Kamen Rider Kuuga continues its epic journey as it roars into its ninth volume! The world has gone mad — a Gurongi has become a turncoat, fighting alongside Kuuga, while Agito’s power spirals out of control! The battles Kuuga has faced have always been simple: stop the Unknown Life Forms from continuing their murderous game. But now one Gurongi rejects their Gegeru, coming to fight alongside Kuuga instead. Can Godai trust this new ally, or will their beastly nature reveal itself? Meanwhile, Yukina surrenders the powers of Agito to her brother… but with another deadly Gegeru underway, can Shoichi Tsugami control the berseker rage of the legendary Kamen Rider?
