Infinite Treasury in the multiverse.

"Be my subordinate!"

"No" I said immediately to her. She looked shocked as if she never heard the word no in her life. Considering how young she looks, its a true possibility. "Besides, why should I and who are you?" I asked her as she looked even more shocked at the fact I didn't know her, I mean, should I?

"You don't know me!! Okay, I am Milim Nava, the demon lord!!" she said as my eyes shrunk at her deceleration. 'A demon lord! Shit!' I thought as her overwhelming aura made sense, even if the items I wore felt like dusty protection. It was quite odd how a young girl like her was even a demon lord, impossible I tell you!

"Again, should I know you?" I asked her and this time she looked defeated at my answer. "Now that I think about it, where are we?" asked Milim Nava with a questioning look. "We are in my shop, treasure Spot, somewhere in London" I said to her as she looked confused. "London? Where is that, Inglesia?" she asked as I had no idea, realizing she does not know about other worlds. 

"Other worlds! So you're an otherworlder?!" she shouted as she pointed her dainty finger at me. "Other worlder?" I asked her, even though I think I could infer the meaning. "Yes, someone from another world that crosses over into ours. You know what, you should become my subordinate!" she shouted, sneaking in her offer and I was considering it seeing as her power seemed enormous. 

"What would I even get if I joined you?" I asked her, seeing if she offered anything special for me to consider. "Uhh..." she pondered and my response was already probably gonna be no anyway. "How about this, wanna be friends?" I asked her as she snapped her head back to me. 

"Of course, Were besties now!" she shouted as I sweat dropped for a moment. 'I said friends, not besties' I thought but I kept that to myself, considering the demon lord before me. "Man, the others are gonna be jealous" she said I enquired what she meant. "Oh, the other demon lord! I bet Ramiris will be head over heels in jealousy" she said as my eyes bugged out and I collapsed.

I awoke with the demon lord poking my cheek. "Hey now!" I said as I stopped her mid poke as she seemed glad I was awake. "I'm glad your awake!" she said as she went back behind the counter. I sighed as I felt her now grab my hand and lead me outside, saying "You should meet my subordinates!" 

'Why?!' I thought as I was now in a castle that seemed bare and grey. It was seemingly carved into a mountain peak and had some human like beings patrolling the castle. The ones of note was a man with a bald head and one who had grey hair and each wore priestly robes that seemed modified for mobility. 

"Hermes, Middray! Meet my best friend Jack!" said Milim as her followers seemed shock. "What! A best Friend!!" screamed the bald one who looked shocked. I mean, I guess a human was not a typical best friend for a demon lord, especially a weak one. 

Hermes walked up to me, and seemingly eyed me up and down and stuck out his hand "Hermes" he said as I took his hand which emitted a pressure on my bones but they didn't break, probably due to the vault. "Nice handshake there" said Hermes as he let go of my hand. 

Middray was looking at me with critical attention, apparently deeming me unworthy of Milims position of bestie, but one look from her kept him from even saying a single word. "Alright, any friend of Milim is a friend of ours" Middray relented, and Milim seemed happy at this. 

I then invited them back into the Treasure Spot and brought some tea for them to drink and some cakes, which I found somewhere in the vault, fresh and even warm. 'Cheat' I thought as I sat down with them as I explained the shops functions to them. 

"Do you really carry anything?" asked Middray as I nodded and waved my hand, opening the door into the vault proper. Their eyes were wide as expected and Milim immediately dashed inside, and Middray and Hermes bolted right on after her. 'Huh, those with powerful abilities are said to have 'quirks'' I thought as I tasted one of the cakes which was the best I ever tasted. 

It took a minute for them to come back, and in Milim's hand was a couple weapons and artifacts which I new the purpose of. An improved Draupnir ring to store energy, a weapon said to have been forged in a substance called 'Stardust' and even a spear which I could immediately recognized as the heavenly jeweled spear, Ameno-nuhoku. My eyes bugged at this as I realized what items she apparently wanted. 

Before I could even get a word out, the door opened again and in came the most snazzily dressed skeleton I ever seen. He wore black academic robes with a golden trim, his fingers covered in magical rings, and a staff by his side that eminated great power. He looked confused on where he was, while Milim had a glow in her eyes. 

"You look strong! Become my subordinate!" she said with absolute confidence as the calm skeleton, lich thing, said "Im good" immediately and Middray felt offended and tried to put a punch in his direction but the vault said [No violence!] in a cutesy tone. I already felt like a head ache was coming on as I introduced myself to the skeleton thing. 

"My name is Jack Croftman" I said to him. "Nice to meet you, I am Momonga!" he said as I wanted a question. "Momonga? Are you japanese?" I asked him as he looked shocked at this turn of events. "How did you know?!" he said as he readied his staff as I said "A lucky guess" as he calmed down and I began to explain to him the details. 'Maybe I should put up a sign' I thought as we got to talking.
