Naruto: Becoming Kakashi's Human Power Bank

[Hokage fanfiction + Ultraman Tiga + action-packed + hilarious] “Bushigomen, how does this kid use ninjutsu like it doesn't cost a thing? He's using his ultimate moves like basic attacks!” “Hehe, you didn't know I can absorb light to replenish my chakra, did you?” “Kakashi-sensei, you're looking pretty drained! Let me help restore your chakra!” “Madara, are you worried my beam might not be able to pierce your Susanoo?!” “Bushy-Brow-sensei! Why aren't you kicking Madara in the head with Night Guy? Good thing you've still got another leg. Go on, I've already healed you with light!” [Every chapter ends with a little bonus scene, so you can look forward to that ୧(๑•̀⌄•́๑)૭]
