Episode 1

Beginning
The episode begins with Cube singing and sitting on a rock in the middle of a storm in the rain. He gets a "Call" from his brother, Cubical. Cubical asks Cube where he is and that he's been looking for him. Cube says not to, and that he "needed some fresh air anyway." He hangs up and then hears a baby crying. It turns out to be Cyan with his wing caught on a branch of a tree. Cube saves him and decides to take him home. Then, he starts singing to him. Meanwhile, Cubical, who was looking for Cube, spots his umbrella on the ground, and picks it up, looking worried. He then finds Cube, and hugs him. Cube says that Cubical didn't have to look for him. Cubical then hears Cyan, and moves back, startled. Cube explains how he found Cyan, and Cubical says that he will allow Cube to take him home.

Middle
Later, while they are eating, Cyan shoots a beam from his chest, acting like a projector, showing Pyrahedron, who explains that Cube is now the fourth caretaker of the Tree or Life and that he has one day to reach the tree and seal the monster. Gold pops up and interrupts the call. After Pyrahedron hangs up, Cube says that he'll go the the Tree. Cubical asks how he is ok with all of this. Cube then says that he wasn't until he saw Gold in the call, and realized that he looked similar to Cyan. He said that he thinks Pyrahedron was serious, and decides to head out in the morning.

The next morning, as Cube gets ready to head out, Cubical asks if he's really ready to do this. He reminds Cube about his previous encounter with the monster. Cube gets a flashback of Dub shooting a laser beam at his head. Cube reminds his brother that he survived the incident and that he will survive. Then he tells Cubical to stop worrying about him. Cubical agrees but tells him to at least eat before he and Cyan leaves. Cube agrees.

An hour later, Cube is walking while holding Cyan, who was fast asleep. A blurry figure dashes behind him. He looks backs and sees nothing there. He keeps walking, and stops in front of a huge pink lake, looking shocked. Knowing that he can't go in the water, he wondered how he was going to get across.

A blue boat then appeared, and asked Cube if he needed help getting across the water to get to the Tree. Cube agreed and thanked him. The boat said that he went by the name Ketches. He then explains that he's helped all the caretakers before Cube as well, and tells him to hop aboard.

While they are sailing, Cube introduces himself to Ketches and asks him who the other caretakers were. Ketches says that they are Iris, Pentellow, and Pyrahedron. He then explains that ever since Cyan has been born, Iris and Pentellow have been missing. Cube hopes that it has nothing to do with the monster. Ketches agrees, and then they stop at the Tree of Life.

End
Ketches drops Cube off at the Tree. Cube thanks him and Ketches warns him to be careful. He says that it looks like a clear path, but there could be someone hiding and lurking around. Cube agrees, and walks toward the Tree. Suddenly, a group of flower children attack Cube, and his head falls off of his body. Cube says he will not fight children, even if they're corrupted. One of the children says that they will not fight, but Cube will be in a lot of trouble. She hits a gong, causing the sky and the Tree of Life to turn pink and black. Heli is seen for a quick second, before flying away. Dub comes out, and the episode ends.
