Mr. Ueda is Hideki
's former and Chii
's current boss. He has an interesting story, one part of it is being married to a Persocom named Yumi
. (This later causes Yumi Oumura
to feel jealous). Mr. Ueda can't do math and that's why he purchased Yumi
, but he later fell in love with her and married her.
When he was interviewed on his wedding day about the marriage, he said that he was unsure because he wasn't
sure that he could make her happy. After a year or so after the marriage, Yumi's memory failed her and in the end she was run over by a car (coincidentally saving Mr. Ueda's life). After that, Yumi Oumura came to work for him and they fell in love (until Yumi Oumura found out about Yumi Ueda).
