An android maid named Pao serves three individuals - Ai, Mako, and herself. She follows the "Intergalactic Maid Law," which includes provisions such as granting maids one day off annually. Despite being an android, she possesses a "Maiden Chip" that enables her to experience love. This chip reacts to Ichigo's presence, causing her to actively pursue his attention. Eventually, Pao switches sides and joins the GRA after falling in love with Cosmic Banchou. According to the OVA, she successfully marries Ichigo after Sanada grants permission for their union following Ichigo's unknowing acceptance of a rose as an engagement gift.
