Cerevo is a coined word that expresses the idea of "REVOlution of Consumer Electronics." Cerevo is not a yo-yo manufacturer, but a Japanese company that plans, develops, and sells IoT-related products. In 2016, Cerevo developed the "7-Magic," a super-bright light-up yo-yo with a programmable LED, based on the looping yo-yo "Initiator" by C3 Yoyo Design. Developed in collaboration with BLACK, a world yo-yo champion who has performed in "Cirque du Soleil," the company created a product that can be called the pinnacle of performance yo-yos, an unprecedented yo-yo equipped with Bluetooth that can freely change the color of the light to match the sound and video. This innovative IoT yo-yo, created from a different perspective than yo-yos as a competition or toy, gives a sense of new possibilities for yo-yos.
