Jun has gone through 180 upgrade cycles, and as it grows more robust, it has increased in renown and reputation, so that in 1998 there were more than 200 downloads in the first month that a new version was announced.
Jun has been developed as an architecture that is trying to break away from the bias of programs being limited to number and letter crunchers, i.e.
Jun is the first 3D graphics package released as free software for which object-oriented methodology has been applied in all phases of analysis, design, and programming.
Jun is a Dao-Shi, a person who can control zombies using paper seals on them.
But when Yoh frees him from Jun's control by breaking the talismon on Lee's forehead, Lee remembers how he died and goes into a vengeful rage against Jun for her family murdering him and for all the bad things she had made him do.
Yoh integrates with Lee's old master and manages to calm him, saving Jun, as well as giving Lee a new purpose, to stay as Jun's partner and to achive his dream of perfecting Dao Dan Do.
