A younger Ueda seen in a flashback accompanying Yamamoto before her transition, when Johji brings her a "san" present to supplement the previous "kun" present.


Sebastian is a butler who is addressed by Isabella after the opening credits of episode 9. He initially refers to her as "obo-chama" which she doesn't like, and she requests he use "ojo-sama" instead. He agrees but only on the condition that she refer to him as Ueda, presumably his real name.

Ueda essentially raised Daisuke in the absence of parents, and took some flack for the resulting lifestyle choices, but he takes pride in the confidence that Isabella shows.
