Background
A ninja monk and scholar, Chūkaku taught Chiruku sometime before his death and was eventually interred at the cemetery in the Fire Temple. Kabuto would later reincarnate him by accident while looking for Chiriku.

Personality
Being very calm and seemingly enlightened man, Chūkaku opposed violence, but like many of the other reincarnated shinobi, resigned himself to his fate. He claimed to have been quite ignorant in life.

Appearance
Chūkaku was short, thin man with a bald head, a long and thin grey beard, and broad features. He wore the typical garb of ninja monks.

Abilities
While claiming not to be as powerful as his student, Chūkaku instead possessed knowledge on techniques' formulas. He also displayed an ability where he could use a set of rosary beads to nearly undo the seal on the Third Raikage before being ambushed and sealed.
