Ooh, that explanation for the name difference makes a ton of sense. I will say though, I'm pretty sure Mikoto is Sano's first name, not his last, thus the nickname "Mii-kun"
Ah yea, now that you said it, I need to be corrected. I forgot the last name comes first hehe thanks!
I think no-mikoto is like a title for God, since i see some japanese deity also use no-mikoto so some games and manga just use Susanoo. also it's ancient name so it probably doesnt follow the current last name-first name convenient. but it is possible this manga use Mikoto as last name, it is not impossible to use last name as nickname. but let's just see how it will be explained in this manga
Ah good point! AI says it so too. And yea I read and watched some where they use last names as nicknames Im not really very knowledgeable on this but I really like diving into the rabbit hole when there's like a topic that really interests me haha
So last month I talked about guessing Sano's real name as Susanoo no Mikoto, glad that was right. I can finally sleep at night. jk. So what's left is to uncover my other theory that Yuuta is from the Kurahashi clan a branch of Tsuchimikado clan which are descendants of Abe no Seimei.
Ebisu and Sano don't share the same last name I think it was because Mikoto is really not Sano's last name. Gods dont have last names. Probably just took Mikoto and make it as his last name. Also for Ebisu's last name Isaburo, lore says when Ebisu was abandoned/casted away for being something like "defective" (no bones or broken bones I think) a fisherman picked him up and adopted him so I guess that's why his last name was different. I would also guess that Ebisu is also the name that was given to him. I mean this is just another guess.
