Sinclair is a Salsu in Blade Lineage syndicate. Sinclair is a kind-hearted and anxious person, he isn't sure if he enjoys killing and harming people. Timid, but very calm and violent while fighting. Wishy-washy, overdependent, inexorably insecure. Sinclair fights with a jikdo, a straight blade, which handle has a red tassel tied to its end. He's quite talented in drawing and painting. Sinclair values family, seeing his syndicate as one, being very close with them.
