annie(John Pluto Smith) mentioned previously that Artemis turned a bunch of people into animals? Maybe Godou will try to go for a visit and turn the humans back to normal as a return favor. And of course, all the girls will fight over who will help him forge the sword :3
Adding onto this....Here's my imagination running wild ;p
there will be an epic battle with one of the gods and at some point Godou dies(again lol). God gets help or does something cheap so Smith is at a disadvantage then Godou revives thanks to the ram, much to the surprise of Smith and his aids(Some guy mentioned previously that she was after).
Smith "Really...To think that you can revive from the dead. You never fail to surprise me, Kusanagi Godou. However you are late! Much too late!"
Godou: "Hmph....Well if I were to borrow your words then I'd be 'fashionably late', no? Besides, you are called John Pluto Smith, King of the Underworld! You of all people should know that not even death can stop me, Kusanagi Godou, Devil King of Japan!(Champion of the rising sun?
)" yelled Godou in a rare moment of joy. His smile resembled a beast that could no longer suppress the joy of battle. Godou thoroughly soaked in the adrenaline of the battlefield and made his way foward until he stood shoulder to shoulder with his "brother"
For the first time ever, John Pluto Smith was at a complete loss for words. He somehow had the feeling that a similar situation happened recently with a certain divine ancestor(Asherah Volume 6 chapter 1
) He then realized that he was smiling for some unknown reason. Of course, no one else knew this because his face was obscured by his mask. "Sigh....What a troublesome person you are. Very well, as your senior in combat, I will show you how a true battle is fought!(In style~!)"
