Ta-da~ It's Sancho, the true form of our Don Quixote! Actually, Don Quixote is a pseudonym, and her real name is Sancho. She is a Bloodfiend of the Second Kindred. The name Don Quixote is the name of her Father. Her outfit at this time is the same as what Don Quixote usually wears, but the difference is that the clothes are stained with blood, and she wears a sheep's wool mantle on her left shoulder created through Blood-weaving, a unique Bloodfiend ability. Sancho's family currently consisted of the Elder Don Quixote, foster sisters Dulcinea and Nicolina, and various other Kindred like Curriambro, but most are now dead. The reason is that 200 years ago in La Mancha Land, the family members, exhausted by hunger, stabbed their Father. The Father then sealed La Mancha Land, and after 200 years passed, he reopened it and was indiscriminately capturing P Corp. civilians to consume their blood. Therefore, Limbus Company, various Fixer Associations, and Wings subjugated La Mancha Land, and they are now dead. Because of this, she holds a longing for the time 200 years ago and is secretly lonely. Her personality is the opposite of the original Don Quixote. She is quite prickly and cold. Oh, but she still remembers the time spent with the Sinners, so she is friendly with them. Instead of the original lance, her weapon is a spiral lance made through Blood-weaving. She is very strong, so if she goes berserk, I recommend you ask Vergilius for help. This character only appears when Don Quixote takes off Rocinante and will never appear while Don Quixote is present. She also never appears after Sancho puts Rocinante back on.
