Experimental Fuwamoco
Character.AI bots. You can try to rizz them by being very indirect but CAI is censored af so good luck getting anywhere more than kissing, might have better chances just talking about fun stuff. Character definitions are mostly lore and quite detailed in terms of personality, including details and relationship of both twins, so maybe try asking about that, dialogue style could be completely wrong though.
