Susi is or was the leader of the Bremen Branch of the Pussyfoot Clan. Before the Ninja purge, the Pussyfoot Clan was the biggest clan out of all of the clans in Sylvania has (or is it had) multiple branches.
Some branches like the Kashina Branch were wiped out completely while others like the Bremen Branch was devastated, but escaped complete extinction.
Susi is Trevon's older sister and one of the long lineage of Chrono Ninjas from the Bunerean Homeworld.
Since Trevon is 10 in the Ninja storyline, Susi is 20.
Base was made by debsie911 on DA.
Susi's heels are non-regulation ninja footwear and are more like assassin's wear being they conceal hidden blades in the heels and the heels don't effect her mobility at all.
