Hakuya A Jiangshi. Kaya's older brother who cares deeply for his sister. Lethargic and finds things bothersome, but is actually quite caring. He acts as the brake for his pushy sister, and when he gets angry, he's a bit scarier than usual. A downer type. He speaks with a stereotypical "Chinese" accent, ending sentences with "-aru" or "-yoroshi." He says "moumantai" for "no problem" and "hao" for "good/understood/OK." His exclamation of surprise is "Aiya!" He speaks in a calm, detached manner. First person: I (archaic/formal). Second person: you (archaic/formal).
