This is Cylinders and Coins by Yoichi Akamatsu, winner of the Ishida Tenkai Award.
Yoichi Akamatsu is a shadowy figure who, once he gives a lecture, is always seen by many of the Kansai region’s leading performers.

His effects are beyond the imagination, and his simple tricks make them possible. Everyone is jealous of his talent.
