The ultimate collaboration between the national idol "Haruna Osaka" and school cosplay! Includes 5 costumes that are indispensable for blazer, sailor suit, swimsuit, gym clothes, cardigan and school items! In the classroom, in the changing room, in the health room, and in the playground, a beautiful girl idol spree brilliantly! A very naughty school spring story to send with a national idol! I'm attached to being able to feel like this!
