Corporal Schidera is a rigasian army grunt that was deployed in kesizman territories during the first week of the Rigasia/Kesizma War.

Sadly for him, his unit found some powerful aberrations that were killing them, and then his and one of his buddies were shot by Clark Dubois and Gaia Dynko. His buddy died, but he was saved by the intervention of Maelle Kurimoto.
