Cold, aggressive, loyal, determined, strong, cocky. In general, Chuuya comes off as an irritable and arrogant character, especially around Osamu Dazai, his former partner turned enemy and rival, however he isn’t needlessly ruthless and doesn’t kill unless absolutely necessary. He can be very sweet and loving towards those he truly cares about, but doesn’t show it around others. Chuuya tends to have a softer side around his lover.
