I bet this isn't going to be the same Nagato as the one that loli-fied Iowa, considering she didn't freak out upon seeing her and Yamato.
If this instructor Nagato isn't the same envious Nagamon that loli-fied Iowa, then where's her blue armband then? Even the loli-fed Yamato wore that armband with her karate gi.
Sorry kiddo, this is not the Nagato you are looking for.
Maybe the next strip will tell if the Nagato that Iowa saw in the martial arts class is indeed that Nagamon who's in her admiral's fleet but now nobody will know what's the ineraction between Iowa and the Nagato in this strip.
