Chica Umino & Oberon

I got an artbook about Oberon at Comiket 100 in 2022. I looked at it again today and thought to myself, is Chica Umino the only artist for FGO that did art for a single servant? I think every other artist has done multiple servants, right? I thought that was pretty cool

P.S. That artbook even has a drawing of Guts as a reference to Berserk because its author passed away earlier that year. Really glad I happened to pick it up!
