Kagaku to Mahou no Kasou Sekai Vol. 12

Four days after the great in-game tournament, Akira, Sanae and Seraia were hounded by (fan?) classmates in real life. Akira had an uncomfortable meeting with Ami, the leader of his swim club, by refusing an invitation to participate in the club retreat. Akira already promised his time to Seraia. He went home, got online and along with Seraia and Meru headed for the virtual town of Seaket, where they believed they would find Natalia, the final member of their party.
