When Akio and his mother move across the country to live with a mysterious acquaintance of his dead father, it's an adjustment. When they learn that the man's wife is dead and his son hasn't left the house in years, it's a shock. When the son starts letting Akio in on the rest of the family's secrets, things really start to get weird. It's going to be a long winter.
Slight heads up for abuse for the next few pages! (...As you may be able to predict.) It's not gonna be anything significantly worse than what's been shown/implied already in this comic, but it is gonna be a bit more explicit, maybe.
