Being a superhuman from birth, there is composure and presence of mind in him. Romulus' human nature is that of Rome itself, which rules the world. The Rome. Everything in Rome is the fruition of his own destiny, purpose and flesh and blood; those who were born in Rome and those who died for Rome are equally his own children. That is, he calls other Emperor Heroic Spirits related to Rome, such as Nero, Caesar and Caligula, as "my child" and loves them. Towards Romans, Romulus is very kind. To all those who are not Roman yet interpret the nature of "the world exemplifes Rome", before long, he will interact with them kindly. That is, he is nevertheless kind to everyone. Usually, Romulus has an air of composure around him, but he abandons himself in a blood frenzy to some degree and forgets about himself when he is well into battle. He has an aptitude for Berserker. Once in a frenzy, he is out of control.
