He made them be his apprentices and taught them about building. After two years, Shovel had left them to inspect the Build Kings, and left them with a mission, that the both of them had to, independently, build a house strong enough to withstand the harshness of the island for the next 2 years. In which Shovel would send someone to pick them up. Before leaving Shovel gave part of his headband and his Vigor Saw to Renga.

### Intro Arc

Renga is chopping wood when Tonkachi arrives and asks to be let in his house. Renga lets Tonkachi in and starts to make some tea. Renga asks Tonkachi what happened, which Tonkachi explains how the Trolls had blown his house away. Renga tells Tonkachi that he is going to have to build a more solid house if he is going to live on his own. Tonkachi comments about how peaceful Renga's house is, which Renga says that its because he doesn't build it in an instant like Tonkachi always does. Renga then explains how its been three years since their master left and that he should be sending someone to pick them up soon. Tonkachi wonders if someone will actually come pick them up and tells Renga that he is hungry. Renga says that Tonkachi should work on his cooking, which Tonkachi says that is like another dimension for him. Tonkach then asks if he can spent the night, which Renga says that Tonkachi always spents the night.

The next day, Renga is gathering materials and thinks about how savage the nature is on the island and around it. As Renga finishes gathering materials, he heads back and thinks about when he and Tonkachi first met their master and how he taught them carpentry. As Renga returns home, he thinks about what his next request is when the Trowel Penguins shows up. The Trowel Penguins explain that they homes were destroyed by the House-Eaters, which Renga notices that boss of the House-Eaters and guides the Trowel Penguins into his house.

As Tonkachi shows up and notices that Tonkachi's house is destroyed. Tonkachi finds Renga and asks what happened, which Renga says that he couldn't protect the Trowel Penguins. Renga tells Tonkachi to be careful since the boss of the trolls is different. Renga starts to cry and comments about how he is a failure of a carpenter since his house was completely useless. Tonkachi says that Renga is wrong as his house was able to protect the Trowel Penguins from dying. As Tonkachi takes on the boss of the trolls, Renga thinks about how Tonkachi promised to protect him. Renga also thinks about how Tonkachi always stayed over to protect him and remembers when they became brothers. After the boss is defeated, Renga informs the other inhabitants with Tonkachi at the shore.

Suddenly Renga notices a ship is coming and they comment about how they are going to be picked up. They then says that their master is waiting for them and that their goal is the Build Kings.

Renga and Tonkachi introduce themselves, which the guy introduces himself as Nana and that he too is one of Shovel's apprentices.

After the House-Beast gets up and looks refurbished and Nana explains what a House-Beast is, which Renga asks if there are other creatures that can disguise themselves as houses. The Trolls arrive and explain how their ancestors were pushed to the brink of extinction by house attacks and that the Build Kings were the main force, which Renga comments about how the Build Kings had brought calamity. Renga then goes to the House-Beast and comments about how among all the Build Kings, there were buildings that saved many creatures from natural disasters and that he doesn't get any bad feelings from this house.
