“Smartphone” this, “superpowers” that, I want to see an isekai where the protagonist is one of those young women with an incredibly cluttered purse and that’s what she takes with her into the world she’s been swept off to. And then she uses her purse’s contents to her advantage, and not in a stereotypical way or anything like that, I want this to be Lady MacGyver and her purse of resources. I want to see a pair of nail-clippers with a file on it be used as the multi-purpose tool they can be. I want lipstick war paint. I want to see something really clever done with that handfull of grocery receipts she never threw out. And the title would be something like “I’m Going to Save the World by Cleaning Out My Purse.” And the show’s emphasis is on her being cool, clever, and creative, not on getting as much fanservice in as possible.
Bonus points: During the final confrontation with whatever the Big Bad is, our heroine finally runs out of stuff in her purse, it’s completely empty. The villain gloats about her being out of ammo and stuff, and while the villain is busy doing this the heroine grabs a sizeable rock, shoves it in her purse, and starts using the whole thing as a flail-style weapon against them. The purse and its contents aren’t the source of her power, it’s how good she is at making do with whatever she has to hand.
(…look, regardless of anything else about it, the movie ‘The Gods Must Be Crazy II’ had a lasting effect on me in regards to the effectiveness of a purse full of rocks as a blunt-force weapon.)
Also, when her friends arrive to help her finish off the confrontation, they get in because of all the intuitiveness and creative problem-solving the heroine has taught them, not just through brute force. I want a cool, badass final battle that would also make Jackie Chan nod approvingly at the clever use of environment and items at hand.
Oh! And at the very end, after the final fight’s over and the Big Bad is defeated, our heroine takes a moment to go sit by herself and go, “Well, I guess I finally got my purse cleaned out… empty counts as clean, right? …I need to replace some of that stuff, but they don’t make all of it here…” :/
And then her friends and associates start showing up a few at a time, and one of them hands her a ball of string, because she’s been mentioning the whole series that she really ought to be carrying one at this point. And another one tells her that the alchemist she gave it to managed to replicate that awesome, water-proof war-paint she showed them and sent her a couple tubes of it. Someone else pays her back for a meal she helped them get.
Someone even found and returns her nail-clippers.
And it’s one of those really fun, touching scenes that makes you feel good just to watch it, with lots of acknowledgement of the kindness that has been shown and the bonds that have been made, and it ends with her going, “Huh, my purse is a total mess again… I guess I’d better go on another adventure to clean it out!” And everything feels good and nothing hurts and it’s great!
