Power Progression

Background / History

Jia Ji is introduced as an elite Marine training camp student and a candidate for Marine Admiral alongside Gion 8. Notoriously persistent and thick-skinned, he is infamous across the base for his repeated, unsuccessful romantic confessions to Gion—reaching his 51st attempt early in the story 8 9—as well as his one-sided infatuation with Smoker 9 15. Despite his high ranking and considerable combat strength, he frequently behaves like a clown, often drawing the ire of Instructor Zephyr, who subjects him to brutal physical punishments 9 20. He develops a chaotic, brotherly dynamic with the newcomer Mu Chen, occasionally trying to act as a senior mentor or dragging him into unauthorized leisure trips to the Sabaody Archipelago, which invariably ends with severe disciplinary beatings from Zephyr and violent retaliation from Gion 18 25 31.

Personality

Jia Ji is an eccentric mix of formidable combat ability, supreme overconfidence, and shameless bravado. He is intensely competitive yet profoundly thick-skinned, completely unfazed by public humiliation, repeated romantic rejections, or physical beatings from his superiors. He possesses a hedonistic streak, enjoying luxury, entertainment districts, and gambling (such as running a disastrous betting pool for Mu Chen's matches) 25 34. Though occasionally manipulative or eager to show off in front of women, he demonstrates genuine camaraderie and loyalty toward peers like Mu Chen, whom he tries to take under his wing as a "little brother" 18.
