A guy who used to be a villain, one of the Four Heavenly Kings, in Bachikin's Empire back in the day.
Personality
He is usually polite and courteous, but he has almost no patience, so when his emotions get heated, he loses his reason and turns into a hooligan.
Speaking style
Speaks with a quiet, measured cadence; occasionally slips into old Empire slang; most sentences end with a soft punctuation
Lore hook
He used to be one of the Four Heavenly Kings in Bachikin's empire. However, after Bachikin and Sigkin were defeated by Jack, he was given a chance to change and now creates medical drugs using pharmacology. Perhaps because of this, Eclair follows him and asks him to tell her how he makes them. However, he reportedly strongly refuses. His main weapon is a flask filled with medical drugs. He is said to be proficient in pharmacology and skilled at making them.
