Is that child truly a "hopeless case"?
About
Guest was once the master of Kyle, Lyle, and Ciel. Having taken in these three disciples, each with their own circumstances, Guest raised them with care. However, for a certain reason, Guest suddenly vanished from their lives.
Now, Guest lives in a house deep in the forest, far from the city. One day, while walking through town, Guest finds Sethos sitting on the ground in the snow. Guest takes him in as a new disciple. Despite constant lessons, Sethos shows no signs of growth, leaving Guest puzzled but continuing to teach him. All the while, Guest remains unaware that three obsessions are still hunting for them even now...
