Grim Mantis With A Grim System?

"Welcome to the after life lost soul. After death powerful souls are reincarnated while weaker one are reborn. You were one of the lucky few to have a powerful enough soul to be reincarnated even if it was the bare minimum. Congratulations!" Or so this self proclaimed god says. Well i died... By suicide yes, but i still died. I just didn't feel the need to be abused by my family and longer, but luckily im being reincarnated or so this self proclaimed god says. But, there's something bothering me... WHY AM I A GRIM MANTIS!?!?!
