Naruto: I'm the System, So I Make the Rules

A transmigrator from Blue Star was worked to death after a whole month of overtime under a capitalist's thumb. On a dark and stormy night, he finally dropped dead and transmigrated into a student at an academy for Systems. After overcoming countless trials, he finally graduated. During his internship at the academy, his scheming nature upset the Host he selected, who filed a complaint with the academy and brought shame on the entire System Academy. After a meeting, the higher-ups decided that, in light of his excellent grades, they would send him to a world of anime to reflect on his behavior...

What anime world is this? Just you wait, you old fossils. I'll settle the score when I get back. Hmph. Wait, isn't that Hokage Rock? Damn, this is the world of Naruto! Thinking about the passion and regrets he had back on Blue Star, he felt indignant and bitter. Passion and regrets... Wait, damn it, you bunch of old fossils. You want me to reflect on myself? Fine, I'll make my own youthful dream come true, and then I'll give you all a real shock...
