Welcome to The Life, Sufferings, and Mortifications of Rei Tenmon: A 3rd-year high schooler on graduation day. Unfortunately, this important stage of his life isn’t as exciting as you’d think, since, as his name suggests, he is a complete zero. At school, he has no real friends and will go weeks without saying a word to anyone. His home life isn’t much better, considering how much attention his parents give to Kei, his more popular, successful twin brother. But what hurts the most for Rei is how Kei also started to ignore him, even though the two were an inseparable pair. Dissatisfied with having no answers to any of these problems, he puts up an image of apathy and jadedness. However, he’s going to have to change if he wants a chance of survival...
