Summary
Jiruo serves as an instructor at the Beruchoro Orphanage, holding the rank of Moon/Purple Whistle. This position, which sits just below Black Whistles, qualifies him to train the next generation of cave-raiders. His mentor was the legendary White Whistle, Lyza The Annihilator, and he has known Riko since she was a toddler. As a strict and competent teacher, Jiruo ensures that even the eager Red Whistle Riko does not venture deeper than her experience permits. He disciplines unruly children by lightly striking the tops of their heads to keep them in line. Beneath his authoritative exterior, he deeply cares for the orphanage residents and strives to protect them from the dangers of the Abyss.
