Starting from the bottom can be such a pain!
A young employee of a company wakes up in the body of a 12 year old boy. If that was not mind blowing enough for him, he finally understood the phrase 'Dorothy is not in Kansas anymore'.
Join the new 'Chu' in a strange world much like Medieval times on earth.
See him meet and grow alongside new companions, trade with bickering merchants and scheme against nobles. Witness him kill his first wild animal, his first demon and his first fellow man.
Before most of that however, his main priority was to relieve himself of the 'Hunger'. Not an illness or weird ability, but a true pang of an empty stomach. Because Chu found himself as a proud resident of the village slums.
