Joe, a male Myumon of the phoenix race, stands 184cm tall with a frail physique marked by recurring medical crises—vomiting blood, fainting, and vertigo. His striking features include snow-white hair streaked with crimson and pale pink, scarlet eyes, and three tails ending in flickering flames. He dresses in a red jacket with dark-red accents, black pants, and a single heat-resistant glove on his right hand.

As bassist and leader of DOKONJOFINGER, he commands the band with resolute authority despite his fragile health, wielding a bass dubbed "Final Death Phoenix." Academically, he remains a sixth-year Ash Class student after repeating his first year six times due to extended hospitalizations. A vow to graduate fuels his resolve, though he quietly mourns peers who advanced without him.

Mature yet subtly competitive, he navigates band chaos with a responsible demeanor as the eldest member. His health demands a regimented diet of nutrient jelly pouches and precise tracking via a medical diary. Specialized medication occasionally triggers brief power surges, offsetting his chronic vulnerability.

To sustain himself, he juggles part-time roles as a chef, archaeologist, karaoke host, and skyscraper window cleaner. He holds deep gratitude for bandmates Yasu and Hachin, who supported him after he abandoned baseball, haunted by guilt over a pivotal tournament loss.

Dubbed "DEATH PHOENIX," he wields the FINAL PHOENIX FLASH BIRD technique, earning titles like "Strongest Sickly King" and "Shadow Leader" for his irregular school attendance and rumored dormant strength. His body burns at 40°C (104°F), emitting heat haze during fevers. He favors ghost stories, spicy dishes, and soft Hummingbird cookies, shunning excessive sweetness.
