Abilities and Skills
Taiju possesses an extremely sturdy body, something his friend Senku vouches for him. He is the first human to be able to withstand a kick from Tsukasa without losing consciousness. He also possesses immense stamina, able to cross 80 kilometers in 5 hours. Asagiri Gen has also noted that his stamina is immense. He is also the strongest man for endurance after Tsukasa was put in cryosleep and Hyouga incarcerated. Magma, Ginrou, and Yo notably respect Taiju due to his perk of "limitless stamina" that surpasses even the strongest man in Ishigami Village.
- He moves faster and brings with him some loot.
Since High School, Taiju has never hit anyone and he excels in stamina and endurance.
