Background

Zhou Hong arrived in this universe as a transmigrant and initially supported himself as a construction laborer. His foreman rewarded him for routinely doing the work of two men, while Zhou Hong used his income to care for the grandmother he lives with. 1

He inherited the Ultra Heart, a pentagram-shaped transformation device connected to a special training space. After first transforming, he resolved to use his new power to protect those important to him. 1 2

Joneus explains that while the initial light came from him, Zhou Hong's transforming light became Zhou Hong's own; he compares Zhou Hong to his child. 4 Zhou Hong later operates publicly within the TPC while concealing that he is Jostar, though Daigo ultimately confronts him and receives confirmation. 11 32

Appearance

In human form, Zhou Hong is a 1.85-meter man with a highly developed, bodybuilder-like physique. His muscularity is routinely striking enough to intimidate recruits, overwhelm ordinary equipment, and make him conspicuous even while off duty. 15 40

• Broad, heavily muscled frame with prominent pectorals and six-pack abs. 1 15
• His werewolf Halloween costume relied on his bare torso, artificial fur, tattoos, and a wolf-head mask; Daigo considered him convincing enough to resemble a real werewolf. 33
• In Ultra form, he can reach 70 meters in height. 4
• His giant form is primarily silver and flame-like crimson, with black lines across the back following his musculature. 1
• He has a sharp, angular face and jagged, Seven X-like eyes. 1

Personality

Zhou Hong is protective, practical, and intensely committed to becoming stronger. His care for his grandmother motivates much of his training and his anxiety about future threats; he handles household work, buys food for her, and insists on accompanying her to the hospital. 1 2 29

He combines confidence with a blunt, often reckless fighting style. He readily takes initiative against enemies, taunts hostile forces, and can be brutally excessive against opponents he considers irredeemable. 7 43 44 At the same time, he can negotiate when violence is unnecessary, as shown when he spared a Kyrieloid for payment rather than escalating the confrontation. 6

Despite his intimidating presence, Zhou Hong has a playful side. He teases his recruits, performs a mock ritual with Ida Iryu's sword, struggles awkwardly with dating, and spoils the yokai of Yanino Street with food and gifts. 19 33 41
