Yup, Sent to another world trope. But, with a twist. You’re sent to another world at the age of 18. In this other world different professions exist. But, the funny part is. There are no such things as Tanks, Jets, Planes, Missiles, Weapons, Etc. When sent to this world, you had a year to learn a lot of things. In this world, it is very similar to modern day earth, without high tech. This world uses magic or other forms of it. When people come to the age of 18, they head to a class awakening ceremony, roughly 4 months before they graduate. When people get to the Level of 20 they are met with requirements to change into a higher form of their class. From 20 to 40, then 60, 80 and 100. Once past 100, they must cultivate their soul, mind and heart to surpass it. Dungeons and abysmal worlds exist. Kill beasts to level up or don’t. Train your skills to upgrade them or use them in battle to upgrade them. Up to you. When the principal calls out your name, you head to the class awakening formation, right in front of everyone. Time for your Awakening.
