Nespuri

Nespuri is a main character of the first season and the main antagonist of the series thus far, as well as the arch enemy of Juu Niinpäs. First seen in the pilot episode "Tältä päivältä nämä", Nespuri is shown harvesting the body of recently drowned Juu Niinpäs in Uppolä. He then proceeds to compress Juu Niinpäs' remains into a cube of unknown purpose. Despite Juu Niinpäs' wishes, Nespuri places Retiisi on his grave instead of Ruusu, and hopes that he rests in agony.

Years later, Nespuri learns through Liispa that Juu Niinpäs has risen. He leaves his castle and flies towards Juu Niinpäs' resting place. As Juu Niinpäs is about to destroy Liispa and Kaaleppio's house, Nespuri arrives and launches an attack on him, effects of which remain unknown.

Nespuri is a mysterious figure, and not much is known about him. He has the ability to shape his body strangely and he also has wings when he needs them. It is clear that Nespuri is no human, but the details of his origins remain mysterious.
