Salome Hyakumantenbara

Salome is an very extravagant girl. She pretends being a fancy lady, but she is not ashamed to be rude if it allows her to assert dominance. She proudly exposes her thoughts in a fluent speech, while often finishing her phrases with either the Japanese suffixe "wa" or "desuwa".
