At least in 1st and 2nd singular pronouns:

1st singular:

-Nominative: ize

-Long Objective(used with prepositions): zen

-Short Objective(used as direct and indirect objects, and shall thus precede verbs): ze

2nd singular:

-Nominative: ika

-Long Objective: kati

-Short Objective: ka

The nominative forms of 1.sg and 2.sg pronouns can be seen as adding an i-prefix to the short objective forms of them.

Note: Although Clikli Dialect is not a human language,

being neutral in the alignment of NPs but marked nominative in the alignment of pronouns,

is not completely inexistent in human languages of our world,

the Oirata language spoken on the island of Kisar in Indonesia also shows such a pattern:
