A single sheet of paper is held out in front of you. On it, in large letters, is written:
"Notice of Appointment: Nijisanji Koshien Manager"
Nijisanji Koshien. It is the grand summer stage where many Livers clash with everything they've got every year. Train your players, seize victory, and aim for the Koshien championship. A tournament where you laugh, feel frustration, and sometimes shed tears to create the ultimate summer.
