Naruto: I Play Kamen Rider Decade from the Start, and I'm Righteous to a Fault

[System, lighthearted, invincible, decisive and ruthless, righteous to a fault, no whitewashing the Uchiha.] After a freak stroke of luck, I transmigrated into the Naruto world as the super-grade repeater Kamiyama? And I don't even have chakra? Luckily, I've got my trusty System! Kamen Rider Decade template from the start. Do righteous deeds to raise your compatibility with the Rider template and unlock more abilities. [Ding! Host has killed a traitor. Decade compatibility: 10%! Unlocked Invisibility Card, Clone Card...] Can't use ninjutsu? Eat this, you little punk: a strike from the shadows! [Ding! Host has ambushed and killed 10,000 Iwa shinobi. Decade compatibility: 50%! Unlocked the Old Ten-Year God Card...] Lectures are useless. A broken skull is the best textbook! [Ding! Host has killed Itachi, the traitor who slaughtered his clan. You now fully understand all of Decade's abilities. Decade compatibility: 100%! Unlocked God Mode 21: Passionate Form!] Kamiyama, who makes a habit of doing good deeds, just snapped a mad dog's neck. Who let their dog out without a leash? What are you looking at? Why don't you hurry up and thank Big Brother Decade? [Orochimaru], [Obito], [Nagato]...
