Tayutama 2: You're the only one

Fifty years have passed since the Tayutai were released from their seal in Ashihara-chou, and humans and Tayutai now share the world in fragile coexistence. Yakotami-chou — where Sora lives — has become a showcase for that arrangement, a town with unusually strong spiritual energy that has drawn both humans and Tayutai in large numbers. Everything seems ordinary until Sora breaks up a minor dispute and a Tayutai girl named Kohaku appears, telling him she has been looking for him specifically. She leads him to Yachimata Shrine and announces that she wants him as her husband. Her mother Mashiro provides the explanation: Kohaku wants Sora's help founding the Human and Tayutai Coexistence Society, and she is very enthusiastic about it.
