レイセン レイセン2号
Not to be confused with Reisen Udongein Inaba, Reisen is the Watatsuki sisters' pet in Silent Sinner in Blue, a comic book spinoff series based on Touhou.
Named after Reisen Udongein Inaba. Sometimes referred to by fans as "Reisen II" (レイセン2号) to distinguish her from the original, but may also use the unofficial romanised "Rei'sen" with the use of an apostrophe.
