Jataka is an ancient Indian prince and serves as a big brother figure (older brother-like mentor) to the young Siddhartha Gautama (who later becomes Buddha). He was a just and capable ruler who brought prosperity to his kingdom (Malla) and its people. Despite his successful reign and the admiration he received, Jataka spent his final days bedridden due to a terminal illness. He has a calm, collected, and friendly personality — dignified like a prince, yet warm and honest toward those close to him (especially Siddhartha). Visually, he is depicted with a lean but athletic build, typical noble attire of ancient India, and a gentle yet weary expression in his later scenes due to his sickness. His role in the story is pivotal: his death and final conversation with Siddhartha become the catalyst for Buddha’s enlightenment. Jataka reveals that even though everyone assumed he was the happiest man alive because of his achievements and status, he actually felt trapped — his entire life had been dictated by duty and expectation since birth. He never had the chance to truly live for himself or explore the vast world beyond his responsibilities. This honest confession plants the seed of doubt in Siddhartha about the nature of happiness and worldly success. After Jataka’s death, during the funeral procession, Siddhartha carries his coffin and releases it into the river so his “brother” can finally drift freely and “see the world” as he wished. This moment marks the beginning of Siddhartha’s path to becoming the Enlightened One. Jataka also briefly appears later in the manga/anime during Round 6 to silently pray for and support Buddha.
