This is a genuine open sport car for K-car created by Suzuki in the early 1990s. Its development took place during Japan's unprecedented economic boom, and the elaborate targa-roof structure and four-wheel double-wishbone suspension were designed to be cost-effective. The design, including the 51:49 weight distribution between front and rear, is a full-fledged sports car itself, and although its power output is 64 hp, which is within the voluntary limit for K-car, its cornering speed is capable of overtaking cars with much higher car ratings. Together with the Honda Beat and Mazda AZ-1, which came out around the same time, they are known as the ABC Trio. In 2017, Suzuki announced a campaign to replace the engine block of the Cappuccino free of charge, and it can be said that the Cappuccino is a car that Suzuki is very attached to.

A spirit - an entity from another world that takes the form of an innocent young girl. Despite their dainty appearance, they are objects of awe with immense power. There were two ways to neutralize them. Either we destroy them by force, or... Date them and make them fall in love with you! Shidou Itsuka, an ordinary high school student at Raizen High School, awakens to his ability to "seal the power of spirits" after an encounter with his first spirit, Tooka. The spirits, though feared and hated because of their powerful fighting abilities, have always been alone and have known nothing but battle and death. Shido, the only one in the world with the ability to seal the spirits' power, throws himself into a life-and-death war of "date" with the beautiful spirits in order to save them. Some try to destroy the spirits, others try to save them. Some are driven by hatred, others by desire to use them. As various thoughts intersect, those who truly turn the world around eventually emerge from the depths of darkness. And Shido, too, comes to know the truth about himself! What lies beyond the conclusion of this accelerating story? " The Kingdom has turned. Now, stand back, mankind."

The "Worst Spirit" that Shido has ever encountered and was the only one he could not save. Among spirits that often appear in the human world by accident, he is unique in that he can appear at will from the neighboring world and even kill people intentionally. There is no doubt that they act with a sense of purpose, but that purpose has yet to be revealed. The angel that manifests is "Zafkiel".
