Ah

Ah (アー) was the leader of Gigu and the adoptive father of Agu.

Appearance
As a Goblin his skin is dark green and is of short complexion

Background
In the past, Ah adopted the hobgoblin, Agu, and raised him like his own child. When the forces of the Great Tomb of Nazarick began building the Monument of Ruin, it disrupted the power balance in the Great Forest of Tob. With this new entity inhabiting their forest, Ah presumably ordered the rest of his tribe to split up in order to find a new home. By doing so, however, this weakened the tribe significantly, allowing the Giant of the East to easily conquer them.

The Two Leaders Arc
Agu stated him to be the son of Ah when introducing himself to the Enri Emmot, Nfirea Bareare, and the Goblin Troop.

Agu
Ah appears to have cared about his adopted son. However, Ah appears to have not told Agu that he is adopted or that he is a hobgoblin.

Trivia

 * It was stated by Agu that including him, Ah as at least four sons.
 * Ah was not named among the surviving goblins that escaped the Giant of the East, thus it can be presumed that he perished.
