Character development: a red riding hood inspired vigilante

So recently I thought of wanting to do a short story that fleshes out my urban fantasy setting. Notably, werewolves in this setting. The main character in question is a young trying to avenge his grandmother's death while trying to figure out why she got killed in the process. As with the title, the main character is a male version of red riding hood of sorts. I'm just now developing this idea and trying to make sure not to screw up. If I did, I'll just rewrite it.

• How do you avoid making this character too edgy? Especially with the events leading to his turn to vigilante.

• Is it fine that he was based on a character that was the opposite gender, a la, like Red Riding Hood?

• Should I be subtle with these motifs throughout the story? Even if it has a gang of werewolves in it.

This is what he looks like by the way: red/bloodhood

1.Depends on the direction the story takes. Giving him a group of friends he acts normal around might help. You could also take the spiderman approach; he makes wisecracks while fighting to distract himself, since he's absolutely terrified.

2.If the Fate series can have a King Arthur who's actually a woman, your series can have a Little Red Riding Hood who's actually a man.

3.As far as subtlety goes, I'm pretty sure that since this involves him fighting werewolves, if you give him a red "anything hood/coat related," the audience will pick up on it.

That said, additional details about the setting and storyline might help.

Also, that link isn't working for me.
