When Koku accidentally unleashes an ancient demon, he must enter the magical world of Olori to claim his power. Koku has always felt like he was cursed with a weird name and an illness to match. He thinks life can't get any worse - until he unleashes a demon on a school trip. He expects detention, but instead he's hurled into an impossible quest filled with magical tribes, man-eating monsters and vengeful mermaids. When an assassin is sent to hunt him down, Koku's only hope is to team up with a clumsy shapeshifter and a moody warrior-in-training. Together they enter the JUJULAND JUNGLE, a place filled with dangerous secrets. Can Koku discover his own power, before it's too late?
