Naruto: Starting with the One-Punch Man Template

[System + Comedy + Parody + Snark] No Red Eye syndrome, no cataracts-after unexpectedly reincarnating into the world of the Hokage, Liumu starts off by merging with the character template of Saitama, the One-Punch Man.

Madara: "Why can't even my Perfect Susanoo withstand a single punch from Liumu?"

Nine-Tails: "He's the one who knocked me out with a single punch that night. Otherwise, the Fourth Hokage never could've sealed me."

Sasuke: "I had it the worst! That day, Liumu held his fist right up to my face and asked if I was planning to defect. Tell me, with things like that, would I fucking dare say anything even remotely resembling 'yes'?"

"As long as my cheat is online, there's no problem in this world that one punch can't solve. And if there is, just throw another punch!"
