Gurren Lagann Swimsuits

The Gurren Lagann Swimsuits is a designer swimsuit with a unique pattern made of tiny Kishin eggs. Imagine this; you're watching an anime and you're really hungry for a snack. What are the most likely options? There's a vending machine on the lower level with some chips and candy, but it costs 100 yen every time you want to buy something and it takes ages to give you your change, or there's the convenience store next door with snacks and drinks, but you have to get on the train and walk a long way back to watch your show. Now imagine that this was in the future!
