Pik is aggressive and gloomy (but kind), Varu likes cruel and unfunny (for others) jokes and green paint, Zontik is not a crybaby but soft-hearted, Dante is "wise" (in fact, he just says clever quotes), Felix is for kindness and positive, Kuromaku is smart and slightly old-fashioned (at the level of the USSR), Romeo is a hopeless, eternally flirtatious romantic, Gabriel is just silly and childish and he's also asking really weird questions... According to the canon, they are all 14.
