Plunder the School Bully's SSS-Rank System from the Start

I awakened an F-rank Life Support System and was mocked by the whole school. The school bully's SSS-rank Dragon Soul System crushed me in front of everyone, but I blew up the testing machine with one punch and turned the tables. He can use skills; I can devour his skills. Three months later, the Global Championship will award the champion an SSS-rank System and S-rank military clearance. And the reason my dad died all those years ago is locked behind that clearance.
