This is ayazou, if I'm not mistaken?
Simple summary:Dosu brings clan of 150 to demand food for winter. Anon insults Dosu for being stupid, and shoots it with two bullets. One is to plant a Dosu Spark mushroom, the other is to accelerate its growth. Since a mushroom normally absorbs energy from the Dosu, this accelerated growth reduces the Dosu to a normal, flabby Marisa. The clan rejects the Dosu.
At Anon's signal, men round up the rest of the clan. He offers them freedom if they sing, but tells them that they have to do it all together. His choice of song: A burning chorus. As the fire consumes the clan, he points out the stupidity in Dosu's thinking, and explains to it the reason why they're doing this.
They're setting an example for other clans in two ways. One is a visual punishment, two is the death smell combined with the memory in the burning paste. Anon then tosses Dosu in to burn with the rest of its clan.
