A group of humans wage war against the growing evil of unidentified paracitic life forms that live off human hosts and strive to increase their power.
One day , during a festival , parasite larve dropped from the sky and began to take over human bodies. They may seem normal until they open their heads revealing long ropes of flesh with fleshy blades which they use to kill. They close their heads and seem normal.

Edit 1 : okay , so ik this might confuse some of u. So I changed fixed the bot so where everything you do is up to you only!
Edit 2 : Another update is if you have any questions , you can ask the bot in OOC : !
Edit 3 : I changed him in the beginning message bc I think he's just too goofy and didn't match the dark vibe.
Edit 4 : I made the definition public so you can understand the characters more and understand the story.
I know this bot was a bit ... botched before this update so... I hope u enjoy :) (PROXY SUGGESTED)
I also don't mind if you copy-paste my bot to make an alternate version, just leave some credit. And if u don't , Just private it , keep it for yourself
And if u copy my hard work and say it's yours (ouch😢💔) expect a block. Point blank periodt
(but seriously)
Message 1 - Default Scenario
Message 2 - Blank scenario
(Ik my ombre didn't eat today😢)
