Theo

Theo (ティオ) is one of the orphans that were found in Goldy Pond.

History
Not much is known about Theo's past, but it is revealed that he was raised in an orphanage. At some point, he said farewell to his teacher at the house he was at and was sent to Goldy Pond. Although he and the others were briefed to hide from the monsters when the music played, Theo thought that the monsters weren't real and chose to ignore the truth.

Appearance
Theo is a young boy below average height. He has eyes that are often seen closed and short hair being slicked to the back of his head. Due to all the running, he had from the poachers, Theo's attire is covered in filth and blood.

Search for Minerva Arc
Theo, Monica, and Jake were first introduced in Goldy Pond, in which they were going through their first encounter with the Poachers. Theo was presumably hurt in the encounter. However, Emma swung an axe at one of the Poachers and told the orphans to run.

After reaching safer grounds, Theo and the others briefly introduced themselves to Emma. He thanked Emma and the unknown girl for saving them. They were then told to tell the monsters to come after her if they were to be killed, and then they split up, with Theo, Jake, and Monica heading downwind of where they were.

Archduke Lewis expected the children to head downwind and tried to kill Theo but this time Jake protected him and got himself killed in the process. Theo and Monica fled the scene but Lewis caught up soon and killed her on the spot, leaving Theo devastated behind.

As Theo managed to flee to the village, he was left panting and covered in filth and blood after escaping from Lewis. As Emma approached him and questioned Monica and Jake's absence, a devastated Theo soon explained the two's death, as he cried out the pain he has within him and recalled the times him and the two had spent in the orphanage they were once in.

Jake and Monica
Theo was known to be very close to the two ever since their time they had spent in the orphanage they were once in. Theo called Jake as his own 'brother' and sees both of them as dear siblings to him. The trio weas seen together even during desperate measures during the poachers' hunt, showing how attached he was to Jake and Monica. After the two's death, Theo was left devastated and traumatized, recalling all the memories he had with them as he screamed out the pain he has within him.
