Ep. 1: ¿Desapareció el fútbol!?

1

Alpha appeared for the first time, along with his team, Protocol Omega. Fei Rune appeared for the first time and was seen to bring the captain's band to Tenma. The whole Raimon soccer team appears in this episode as well (except for Tsurugi Kyousuke who didn't appear at all) but they don't remember anything about soccer and about Tenma.
