OVA
Description
Ishishi is one half of a twin boar duo that serves as apprentices and constant companions to the protagonist Zorori. As the older of the two brothers, Ishishi is distinguished from his younger twin Noshishi primarily by his deeper vocal pitch and the absence of a mole on his right cheek, a marking that Noshishi possesses. His appearance is that of an anthropomorphic brown boar, typically dressed in green shorts and an orange vest, sometimes accessorized with a green scarf or blue umbrellas.

Personality-wise, Ishishi shares many traits with his twin brother. Both are characterized by their unwavering loyalty to Zorori, whom they follow on his various adventures and schemes despite their frequent failures. They share a notable fondness for sweet foods, and their actions often stem from this gluttony, leading them into comedic mishaps or causing unintended positive outcomes. Their mischievous nature aligns with Zorori's goals, and they willingly participate in his pranks and schemes, though their clumsiness and tendency to misinterpret plans often create unforeseen complications.

The background of Ishishi and his brother remains largely unexplored in most official media. A single reference in a 1993 film adaptation provides an oath the twins made not to return to their home village until they become successful villains, though this narrative point is not revisited in other adaptations. Their names are derived from the Japanese word inoshishi, meaning wild boar, which is split between the two brothers.

Ishishi's role in the story is firmly established as one of Zorori's primary sidekicks, forming the core trio that drives the narrative. In this capacity, he provides both support and comic relief, and his actions are often integral to the plot's development. For instance, in the story involving the protection of dinosaur eggs, Ishishi actively participates in the group effort to retrieve eggs washed away by a typhoon. Key relationships are central to his character, most notably the strong bond with his twin brother Noshishi, with whom he is frequently seen acting in unison. His loyalty also defines his relationship with Zorori, to whom he remains devoted even when their collective plans go awry.

In terms of development, Ishishi remains a consistent supporting character without significant individual evolution across the series. While his brother Noshishi occasionally displays specific skills such as artistic drawing, no comparable specialized abilities are attributed to Ishishi. His narrative function is as a persistent and reliable member of the central trio, and he does not undergo documented personal growth or standout character arcs that separate him from the group dynamic.
