Shou's BGM description lists her name as 虎丸星 instead of 寅丸星. 虎 "tora" can refer to tigers, felines of the "panthera tigris" species, or colloquially, a "drunk person". 寅 "tora" can be used to refer the tiger as a sign in the Chinese Zodiac, which carries with it the additional meanings of a period of time from 3AM to 5AM, the direction East by Northeast, or January.
