Taburisu is a notable character from the anime Kumarba, distinguished by its unique design as a squirrel-shaped tablet device. This hybrid form combines the features of a small, fluffy mammal with the flat, functional body of a modern electronic gadget, complete with a soft, bushy tail that is a key visual trait. In the context of the story, Taburisu serves as a wise and knowledgeable companion, often taking on the role of a guide for the protagonist, Kumarba, who is a five-year-old bear boy. One of its primary functions is to facilitate travel into the digital realm, specifically the world of the internet and YouTube, an adventure it proposes to Kumarba by asking if they should go and see it.

In terms of personality, Taburisu is characterized as a reliable and composed figure, especially when contrasted with the energetic and sometimes impulsive Kumarba. Its demeanor is that of a steadying presence, using its knowledge to help navigate the challenges they encounter. However, Taburisu has a notable physical limitation that affects its abilities; if its battery runs out, it becomes unable to move, adding a layer of vulnerability to its role as a technological guide. As a device, it supports Kumarba by retrieving information and facilitating communication during their various activities and adventures, effectively acting as a sidekick and a vital tool for problem-solving within the group.

Regarding its motivations and relationships, Taburisu appears driven by a sense of purpose in showing the internet world to Kumarba and helping him learn and explore. Its key relationships extend beyond the main protagonist. Taburisu is a core member of the central group of friends, which also includes a cat girl named Nekolun. Furthermore, there is a significant dynamic with Bagrin, a mischievous virus-like creature who is an antagonist. Bagrin, who is envious of the popular Kumarba, feels a unique connection to Taburisu because Taburisu shows him understanding, making Bagrin curious about and drawn to the tablet character. Within the story, Taburisu plays an essential role in enabling the plot by opening the gateway to the internet and helping to resolve the chaos caused by Bagrin's prank monsters, contributing to the group's shared learning and experiences. The character's development is tied to these ongoing adventures, consistently fulfilling its role as a knowledgeable guide and supportive friend throughout the series.
