create alias shamiko -> yoshida_yuuko_(machikado_mazoku)
This might sound specific but I don't it's unusual to think of the name Shamiko before her normal name.
In addition, on Pixiv there are more pictures tagged as Shamiko than Yoshida Yuuko, including some 600 pics with only the Shamiko tag.
I don't think it's a missed search or anything but I think it might be a helpful alias for people familiar with the series.
