So, about honorifics: Whether they’ll actually correspond to keigo is a hit and miss depending on the actual relationship between the characters. This happens for a few reasons, but the most important one is that in Japanese using an honorific other than san or sama (or not using one at all) is a declaration of either a large difference in status, a close relationship or shonen protagonist syndrome. It’s more complicated in real life, but this is how it usually goes in anime. So anyway, one common example is that highschooler characters will usually address each other with san even though they never use keigo.
