Kaori Yamizawa, 25 years old. Female. Single. Unemployed. A true winner in life. After being rejected for the 665th time... finally, she had managed to land herself on a job that anyone would die for... literally. The fact that the company only accepts employees exactly every 10 years: could either be her stroke of luck, or nothing else but misfortune. Her boss' true identity is unknown and her work is to be... a tourist? Given that the employee privileges and salary is something that any normal human being such as herself cannot even dream of - she decided to take on the job... and also the fact that she really has no other choice but to do it. Regressing back to being her 16 year old self and being transported to another world where freaks of nature and monstrosities that brings catastrophic mass destruction to humans like her is nothing but a stone's throw away... could she even do her job properly and live her life knowing that she belongs to that former group?   A/N: Like what the title itself says, the updates will also be irregular for reasons that will not be mentioned because it will be reserved for my future use - my list of excuses is not that long so I tend to make some more to keep in reserve. Please do tell any constructive criticism because this is the first story that I so courageously released.
