There's a new natural hot spring in Orario thanks to the Dian Cecht Familia, but Naaza of the Miach Familia suspects an elaborate con and needs help to prove it. What does that mean for Bell since he's in the wrong place at the wrong time? It means getting caught in the middle of an ongoing rivalry between two Familias. Again.

Tamahiko Shima is the youngest son of the powerful and wealthy Shima family. Blessed with great fortune since his childhood, he grew up wanting nothing but affection from his oftentimes distant family. After losing his mother and crippling his dominant arm in an accident, Tamahiko fell into deep despair and is cast aside by his own father for his handicap. Condemned to live isolated in the countryside where he would not bring shame to his family's name, he resigned himself to dying alone—until one day, a young girl named Yuzuki Tachibana appeared on his doorstep, proclaiming that Tamahiko's father sent her to be his bride. As she takes care of Tamahiko, Yuzuki brings a feeling of springtime into Tamahiko's dreary life, allowing him to gradually heal from the deep emotional scars of his youth. Their lives slowly intertwine as both Tamahiko and Yuzuki taste the fruits of their first love.

Ever since moving to an in-game world after countless hours of VRMMO grinding, Yuna now calls Crimonia—the city where she started—home.

Nevertheless, this world has a lot more to offer the carefree adventurer. It is up to Yuna to discover these wonders, and perhaps help more people in need as she encounters their various plights.
