Idea 6 creating hero/villain suits with a shopping system

In a world of heroes and villains it's important for them to have protective costumes and gear so they either have their own tailors or make it themselves but them a new tailor has arrived and took the world by storm but this tailor isn't a tailor at all he's a normal dude with a shopping system allowing Haru buy materials and is forced into the tailor business

(don't be surprised to hear the same name)
