The special ops, the secret service. You've heard of them and know a very vague description of what they do. But you've probably never heard of the numbers. Aki Kitsumtu, also known as Zero, is the top agent in the numbers. Sent on a mission to take out a man named Thorn who runs a company threatening the security of the country, he has to take a cover in order to stay under the radar. Being 19, he enrolls in a senior class in high school. There he meets a boy named Samuel, who helps him around the school on the first day and somehow gets close enough to Aki it becomes questionable. On a side job to take out a growing drug lord, Sam follows Aki and gets caught up in something so much bigger than him, and jumps into a life he never expected, never knew about.
