Yu Takeyama, also known as the Mineyama Hero: Mt. Lady, is the No. 23 Pro Hero. Yu is a young woman who seems to enjoy the attention that being a hero gives her and she doesn't feel any shame from having to take that fame from another hero while basking in the glory. She is also shown to be quite vain as she uses her ample sex appeal to further her popularity or to gain something. This vanity also shows a bit of shamelessness, as she isn't above making a lewd pun about her own body.
