Shun's Home Shun's Home:
In this video Shun get's tired of his home and catches a train to a city to get away from his grandpa and from the feeling that his mom isn't there.
As he got to the city he looked around and realized that the only way he could get out of this place alive was to dominate the brawlers there.
As he was there he had a change of heart and decided to come back. But Masquerade and Dan were in the way.
Shun realized that he could do anything if he really believed in himself. So he got past Dan and Masquerade, and made Friends with his Grandpa.
