A/N these are to taken as if the readers are witnessing them.  If you want a specific character from the Nasuverse think either Merlin or Zelretch.  Enjoy 😁

"Why?!  Why did master have to summon him?!" A man in black and red yelled into the table.

After just one sip of his sake he was already complaining.  His partner a man in a dark blue outfit and spiky hair.

"You know, your being even more insufferable then usual.  What about the newbie that had you so wound up?" The man in blue questioned after a drink of his whiskey.

"I don't got a problem with Muramasa himself.  What I have a problem with is the body he's inhabiting."

"I don't really get it.  From what he's told me that kid is a possible descendent of his, that also had the highest affinity with him.  That's similar to Ishtar and Ereshkigal."

"Don't......bring up them please"

"Aw does the big bad counter guardian have a crush on the twin goddesses?"

"Says the man known for having the absolute worst luck out of all servants.  If I remember your legend right Cu Chu-lame, you killed your own son"

"Hmph if it wasn't for our master's order I'd stab your heart with my spear"

"You can try.  Last time you tried I stopped Gae Bolg after you threw it"

"What?!  When?!  How?!  That should be impossible it reverses causality!"

"I'll just tell you this.  Multiverse theory"

The man in blue froze trying to process his drinking partner's words.  To him the two haven't met, except when they both were summoned to Chaldea, by a little girl trying to save humanity by herself.

To the man in blue this is the umpteenth time he's met Cu Chulainn.  Being a counter guardian, and heroic spirit, he has been summoned and fought this man multiple times.  Though this was definitely the oddest relationship they have had in his time as a guardian.

After a while of quiet the Cu Chulainn spoke up.

"I don't understand what you mean.  Though try to explain it and I'll do my best to listen."

"Try picturing the darkest parts of your history got solidified into a human being, then presented to you as if it was no big deal."

"Wow no wonder you wanted to drink this away.  Though maybe I need to find a new drinking partner, your a bit too much of a light weight."

For the rest of the night the two spent drinking and venting their current frustrations.  With the occasional insult thrown in.

A/N the comic above is what inspired this me to write these short stories.  Like I said they are just to fill in gaps.  I apologize that things have been slow for updates.
