A simple question arose one day. What happens if some fandoms and their events take place in the same universe, on the same planet and in the same world, while somehow intersecting with each other? Now with this answer I want to share with you. It all started with a kind fairy tale, telling about friendship and kindness, and a family where there is a child who owns a power...

After the events of Undertale, peace has been brought to the above ground and a new nation is formed.

Sans going in to save them, what comes next is filled with slice of life fun and jaw dropping action. [Updates every Sunday]
