Spoiler

Raichi hates the idea of Mecha Con because of her own family experience. Raichi's father has many wives and Raichi's mother, his first wife, really loves him, but Raichi's father keeps taking more wives, drinking and almost never comes home, making Raichi's mother extremely lonely and sad. Because of this, Raichi swore to herself that if it means to suffer like her mother does, she will never love a man.
