The Volleyball Superstar of Many Faces

Komori Morihiro has been living in this world, where everyone is into sports, for five years. After showing off his talent as a toddler, his excited parents sent him to learn at all sorts of clubs. Tennis, volleyball, basketball, soccer, badminton... Every coach he met wanted Komori Morihiro to train with them. Only Komori Morihiro knew why he was so good at sports: he had a sign-in System. [Daily sign-in successful. Received an R-rank volleyball blocking experience card, lasting five minutes.] There was just one problem with this System: the abilities it gave him were copied from real people. Sometimes, during a match, someone would say: "Did I just see things, or was that block just like someone from Shiratorizawa?" "That serve! That's Kunimitsu Tezuka from Seigaku!" Sometimes, even Komori Morihiro, who had been entrusted with great responsibility, would feel lost. Without these complicated cards, would he still be so popular, just relying on himself? Theme: A life of getting things for nothing really is delightful
