Kumarba, a 5-year-old bear boy, radiates intense curiosity and enthusiasm. His adventures began when he discovered Tabris, a sentient tablet device resembling a squirrel, which offered an escapade and transported him into the internet world, launching his journeys across digital realms.

Personality-wise, he exhibits highly positive traits, deeply loving friendship and actively expanding his social circle. Yet, when situations defy his expectations, he throws difficult-to-manage tantrums. His appetite is defining—constantly hungry, he possesses a strong fondness for food.

Relationships anchor his story. Tabris acts as guide and companion, enabling travel through the internet while providing crucial knowledge for navigating digital challenges, though progress halts during its battery depletion. Nekolun, a 5-year-old cat girl and recent neighbor, becomes a key ally, bonding over shared interests like singing. She displays intense focus on creative activities but reacts strongly to disruptions in her appearance, such as misplaced ribbons. Bugrin, a virus-born demon, frequently targets Kumarba out of envy for his popularity. Despite this antagonism, Bugrin harbors complex feelings toward Tabris, occasionally complicating conflicts.

Within the internet world, Kumarba confronts threats like Bugrin’s chaos-spawning monsters formed from negative emotions. He collaborates with friends to counter these disruptions, responding to distress calls like SOS signals from endangered companions. His actions focus on restoring harmony through collective problem-solving, often crystallized by his catchphrase of frustration transforming into determination.
