I don't think he should be listed as missing in action. Missing in action is a term in the millitary for those who are reported to have never been officially reported of being captured, killed or safely returned. Since we dont know what happened with Inaho(he could have been killed in action), because it isnt stated in the anime,I hence believe unknown is better, since missing in action would imply we know he was reported missing (like Princess Asseylum).

Just my opinion~
