The Michif system is closest to a neutral or accusative system.
All pronouns are unmarked. However, sometimes third person demonstratives are used, and those can be marked for obviation, basically a non-topic third person.
When there are two animate 3rd person demonstratives, one of them can be in the so-called obviative form. This is the new or non-topic NP. It can be subject or object, but most often object.
This is indicated by the verbal morphology.
