This is an escort service where you will get a love hotel and have a lovely young lady come visit you. For an extra $30 they will cosplay as a Ninja hahaha. Service starts as low as 33k Yen for one hour! The reception is in the same building as Tokyo Hentai Club but in the basement floor, first booth when you walk in the door!
