Retarded Isekai

Ever wondered what would happen to a successful salaryman if he is thrown in a mysterious world? For some reason, the reincarnated has turned into a girl. The Reincarnator also has a bunch of numbers on her neck. She lives in an orphanage. However, the orphanage has just one caretaker. The reincarnator is not allowed to go beyond a certain distance from the orphanage. Everyone of six and above has to give a test every single day. The food is good and life is cozy.
However, the technology is too old for 2040s. The library also doesn't have any book with information about the current world. The reincarnator doesn't even know where the orphanage is located! How can she survive?! What if something goes wrong?! After all, the Devil will throw her in Hell for eternity if she gets killed or dies without any natural cause before reaching old age!!!

There was also an alien coin who gave her some ability granting water bottle.
She also got a weird smartphone which somehow connects her with people from different worlds...

How will she survive?

The MC has personality similar to Tanya from youjo senki. The story will be pretty similar to Youjo Senki as both the MC and Tanya(before she reincarnated) hail from the same world. So, more Being X bashing.

There will also be a chat group thingy as chat group fanfics are popping out nowadays.

I am writing this for fun...
There won't be any constant updates...
I own my OC's...
My grammar is pretty bad...
Shut your brain while reading this as the story may make no sense...
I don't know why am I even writing this...
