Zoku 11-nin Iru!: Higashi no Chihei, Nishi no Towa

Having been admitted to Cosmo Academy, Frol and Tada are now having a rough time adjusting to a couple's life, with Tada regularly outperforming Frol in academics - and, to their chagrin, popularity. While the two try (and often fail) to navigate this change in relationship dynamic, they then receive a warm invitation from their old friend, King Mayan Baceska, to visit him at his palace on planet Aritosca Le during a month of holiday festivities. However, Tada's intuition begins to give him ominous and mysterious visions regarding King and the two set off to meet him, and potentially save him from an ill-omened future.
