The group's popularity soars after a blogger's favorable review, thanks to Retsuko's performance in singing death metal. Hyodo proposes of selling CDs with handshake coupons that will allow the consumer to shake hands with the idols for a few seconds. The CDs sell out quickly, and the group takes off for a concert in Hokkaido. Concerned by Retsuko's odd behavior, Haida secretly tails her to Hokkaido. At Hokaiddo, Haida befriends Tadano, who flies him back to Tokyo. Back at the concert, the blogger who boosted the group's status shakes hands with Retsuko, and is revealed to be Komiya. Komiya promises Retsuko to keep her idol life a secret at work.
