鹽川的Fgo美服相關訪談 提到了月姬活動和saber lion
蘑菇希望月姬活動做成聯動形式但是鹽川還要再看看，saber lion不太確定，但是我們（
staff）也很希望有一天能實裝她

以下原文的最後一段
TONO: Finally as the last question, will we ever be able to see a Saber Lion s
ervant or a Tsukihime collaboration event?
When it comes to Tsukihime, even Mr. Nasu would love to do a collaboration, bu
t we will have to see. For Saber Lion we’re not quite sure... but we do hope
to have her one day! [laughs]
