couldn't he have just put it in his inventory

first

I'm pretty sure there are only natural hair color in naruto

first

hair is also made of keratin, so can't he make a whip out of hair?

can't he just retire?

i would have just 'kidnapped' his 'little brother', if you know what I mean.

my soul cracks everytime an author speaks the obvious in this way

and also don't shy away from long descriptions, make them detailed and to make a better picture use things you see in everyday life as inspiration

*writing tip(s?)* instead of saying "they ripped our claws out of our hands and feet!" say "they took our claws!" or something similar because it feels more like they are speaking to me to get the info to me rather than each other and that makes their communicating sound odd and unnatural to me. instead of addressing the subject directly, try make a more natural approach, not directly telling the reader but letting them know through other means, like describing the fact that their claws were pulled out earlier in the story by saying they had no claws when you first introduce them. instead of describing something once in detail, slowly paint a picture by adding hints here and there, as an example, when describing characters describe what the mc sees e.g. I saw a hideous green goblin wielding a roughly hewn stone spear in all of it's hairless glory, a ratty loincloth desperately clinging onto it's waist like a rock climber on a dusty cliff face as it crumbles away in his hands.
