Isekai Tenshoku Undead Works

Keisuke Inazuki is reincarnated in a different world when she is overworked by a black IT company! It is far from the "I'm the strongest!" development and she is forced to get a job at an IT company in that world. I became a zombie and my colleague are undead, rich in ecology as well as individuality. The customer is a familiar monster... Even if I want to die, my next workplace won't let me.
