Trying to find an anime about a group of espers inside this isolated zone
Okay, so before we start, it isnt Blood blockade. It was an anime that started with this group of espers (maybe 10+) who were helping maintain and protect this little settlement of people inside this isolated barrier. There was a bad guy esper who kills a dude during a deal in the early episodes, but he is actually like part of their esper group from before the barriers creation. The espers accidentally made the barrier when fleeing from humans but they didn't realize that, and then they feel bad because they were the cause of the suffering of the people inside the barrier that they were trying to help, so they try to combine their powers to escape the barrier.
The little settlement was like a generator and makeshift technology settlement because they were isolated from humanity so no supply chains and stuff, so the espers use their power to help make life easier from them. They have one who is like a doctor too and one who is a mechanic and stuff? I can't remember the name of this anime, I think it's pretty obscure because I can't find it anywhere. This is driving me absolutely nuts please heeeeelp
