Tsukimichi: Moonlit Fantasy (Light Novel), Vol. 12

Production of Season 3 Confirmed!
After arriving in the demon realm, Makoto and his companions are met with a surprisingly warm welcome—even by the Demon King himself. But the peace is short-lived.
During a goodwill match between Makoto and the Demon Generals, chaos assassins aligned with the anti-Demon King faction launch a sudden attack, plunging the arena into turmoil. Though the assailants are quickly subdued, the true threat has only just begun.
The divine artifact they unleashed summons a fearsome Greater Dragon. As the creature's devastating roar threatens to reduce the town to ash, the members of the Kuzunoha Company rise to the challenge, determined to protect what they can.
