This takes place during episode 1

B127 was currently in the underground, in some sort of castle, He then was called to the throne room where he bows down to a dark shadow

B127: master, you called

???: yes I did, I'm gonna need you to go get me something, I want you to go get me a katana named the blade of vengeance

b127: but that's almost overkill, ill die out there if I try to get that blade

???: I don't care, this is the way on how you can become one of my loyal allies

B127: but what if...

Before B127 could even speak he was cut off and sent out to the overworld where he began his journey to find the blade of vengeance, but then he runs into Cyon

So now you have some context on why B127 is doing this, anyways episode 5 should be coming out rather tomorrow or the day after that, depends on how I'm feeling
