John Berson

John Berson is Kuzk Academy's leading young tanker and Hein Kraaijenschot's early benchmark and rival.

Biography

Academy champion and conference clash

John is identified among the strongest first years from the major academies and joins Ren's team during the exchange tournament. At the Iron Fortress event his greater size and resources let him outlast Hein Kraaijenschot, making him the standard Hein wants to surpass. Years later, John finds Hein at the interspecies conference, assumes he has entered without authorization, and tries to detain him. Ren intervenes and tests Melissa's Magic Cards against John's shield; two fire effects engulf him, but his defensive specialization limits the injury to burnt hair and exhaustion before Donna extinguishes the flames. (Chapters 204–243, 395–396)

Appearance and personality

John is exceptionally tall and bulky, with short brown hair, brown eyes, and a prominent nose. He laughs heartily when meeting teammates but becomes rigid and suspicious when enforcing conference security, acting before verifying Hein's explanation. (Chapters 209–213, 395–396)

Powers and abilities

John is C+ rank by Chapter 395 and regarded as a promising future S-rank tanker. His refined shield stance presents no obvious opening and remains immovable under Ren's physical impacts. Defense does not make him immune to effects attached directly to the shield: stacked fire cards overwhelm him until Donna intervenes. (Chapters 243, 395–396)

Relationships

• Hein Kraaijenschot: John defeats Hein in Iron Fortress and later challenges him at the conference, serving as his recurring defensive benchmark (Chapters 243, 395–396).
• Ren Dover: Ren uses John to test Magic Cards, exploiting his confidence in his shield while avoiding fatal injury (Chapters 395–396).

Items

• Shield: John's large, unnamed shield supports a refined defensive stance and withstands physical blows, though attached magic cards bypass its ordinary use (Chapters 243, 395–396).
