"Momo, thanks for coming, we need you to teach the Orks how to shoot better." Kinoko says desperately. "We just don't have enough ammo."
"I think I can help." Momo answers. "I practiced a bit with cannons."
"Excellent, let's go now." Kinoko says, grabbing Momo's arm and running off.
"A'right you grots, it shoota practice!" a nob shouts as a few shoota boys line up in front of a makeshift gun range. "This humie be 'elping us." This earned him a few grumbles about humies not knowing nothing and all that.
"Well your shootas are just automatic weapons so I'll just create something similar and we'll get started." Momo begins nervously before creating a machine pistol.
"Did dat girlie just make dakka?" An ork asks.
"She did." a nob remarks.
"Can you make bigger dakka?" An ork with a particularly large shoota asks.
"Well... yes..." Momo responds awkwardly before creating a cannon.
"She's the Dakka god!" an ork declares. And word quickly spread across the camp, the 'training' quickly forgotten.
The whole warband was soon surrounding Momo and spreading her 'accomplishments' around.
"I 'read dakka made by the dakka god never runs out of dakka." an ork says.
"I seen her make big dakka from nothin'." an different ork claims.
"Of course she did, she the dakka god. WAAAGH!" an ork argues before punching the offending ork.
"WAAAGH" nearby orks shout and a small scrum begins.
As the fighting gets closer to Momo, Kinoko whispers into her ear. "They respect strength, fire off a few dozen rounds to calm them down."
Momo nods before creating a pistol calibre rotary gun and firing off a long burst.
"No fighting near me if you want your own gun!" Momo shouts and immediately the orks quiet down and with only a few punches thrown, line up to receive 'gifts.'
"She needs offerings of food!" Kinoko shouts and the orks scramble to bring the finest grub they had. It wasn't that good, but it was enough for Momo to supply the bigger orks with guns.
After this they had a long celebration with a lot of celebratory gunfire, enough to bring several teachers over to take a look. They were used to a bit from the ork camp, but this was an alarming amount.
"You didn't" Aizawa says in despair upon noticing who was supplying weapons to the orks.
"We're doomed." Present Mic cries.
From that day forward Momo would occasionally visit the ork camp to create weapons for them. She quickly noticed she no longer needed lipids to make guns, and all guns she made never ran out of ammo. When she asked Kinoko about this all she got was "the Waaagh does mysterious things to it's gods."
AN: look a bonus chapter I never expected to write, but when I was posting this on Ao3 I had an idea, and as usual, nothing good came of it, nothing good for Aizawa I mean.
