This Devil Loves to Help Others

According to legend, there is such an exchange that exists between illusion and reality, and only those who are destined can see and enter it. Some people say that it is paradise, because there you can get everything you desire, whether it is money, love, talent, beauty or longevity... Some people say that there is hell, because what you desire is not free, and the price of this transaction will gradually corrode your soul... Anyway, as long as you enter this exchange, you can get what you want regardless of your needs, but you must pay an 'equal' price. Traveling to this special Tokyo during the economic downturn, there are sentient beings everywhere who need a helping hand. Makino Chigusa, who is bound to the Devil's Exchange, decided to follow her heart and become a "good person" who is willing to help others.
