Shin

"'[Shin] will be the toughest battle so far, so be prepared for a long, all-out war!' ~ PRIMA's Official Strategy Guide"Shin is a demon manifested by the Sorcery Globe, and hand of the Ten Wise Men. He is battled thrice, but is finally defeated only in the third fight.

Shin is leader of a massive army of monsters from El, responsible for the invasion of Lacour continent. The reason for the invasion, as explained in an interview by lead writer Yoshiharu Gotanda, is to seek out an energy stone capable of functioning as a Quadratic Key, to activate the Sorcery Globe and send the Ten Wise Men to Energy Nede. The invasion was made irrelevant, however, as Shin discovers that the Lacour Hope is powered by such energy stones.

When not in the field, Shin resides at the top of the Eluria Tower, a room away from the chamber of the Sorcery Globe. He is always accompanied by an entourage of Stonestatue demons.

Story
After the events in the Hoffman Ruins, the party is directed to the Lacour Front Line to await the arrival of the Lacour Hope and to defend the line from the onslaught of demons. To all's surprise, Shin shocks the Lacour Front Line with a personal attack on the army. The party must simply survive for 60 seconds. When time expires, Shin flees.

After the Lacourian scientists use the Lacour Hope, extinguishing the entire invading army of the Ten Wise Men, a decision is made to counterattack El. The Heraldry weapon is loaded on a boat, and the armies of Lacour and the party with it. Unbeknownst to them, Shin had seen the power of the Lacour Hope but survived its blast. He attacks the ship and the party, vanquishing the player's party and stealing the Lacour Hope's energy stones. He then dismantles the weapon and tosses it and the party into the ocean.

A final battle with Shin occurs at the final floor of Eluria Tower, guarding the entrance to the Sorcery Globe. This time, the party is able to defeat the demon.
