Jade Cocoon 2 (玉繭物語2 ～滅びの蟲～ , Tamamayu Monogatari Tsū ～Horobi no Mushi～, literally The Story of the Jade Cocoon 2: Insect of Destruction) is a 2001 role playing game for the PlayStation 2 and sequel to Jade Cocoon: Story of the Tamamayu by Genki.
The game features a full 3D polygonal world, 200 cutscenes, and full voice-overs. The character designs for the game were by Katsuya Kondō, character designer for the first game as well as the Studio Ghibli films Kiki's Delivery Service and Ocean Waves. 
The game occurs 100 years after the events in the original Jade Cocoon. The time of the Nagi people and "cocoon masters" has passed. New "cocoon masters" are now cited as "beasthunters" and are the prominent force of monster raising, with the player playing one named Kahu who visits the Temple of Kemuel in the hopes of becoming a beasthunter and having adventures like the old cocoon masters he's idolized. However, Kahu encounters trouble during his license exam required to become a full-fledged beast-hunter. He encounters a young fairy named Nico, who leaves Kahu cursed, and he's given a very short time to live before his body is consumed by evil.
Kemuel Temple's resident guardian, Levant - the hero of the original Jade Cocoon - offers Kahu a chance to heal himself. By utilizing the four magical orbs found in the heart of the elemental forests and a dark lute, Levant will be able to save Kahu's life. Kahu now sets off on his adventure, to save himself and eventually the world. Other characters from the first Jade Cocoon also appear, like Kikinak, who became a rich shopkeeper thanks to Levant. A statue of Mahbu, the Nagi Maiden, can also be seen at the room where Levant is.
The game received "generally favorable reviews", a bit more positive than the first Jade Cocoon, according to the review aggregation website Metacritic. In Japan, Famitsu gave it a score of 31 out of 40.
