Nice to hear, speaking about Touhou MUs, i remember you listing that Puyo Puyo gal as Reimu's best MU and i've found a MU for Reimu that sounds pretty good and i kinda want to hear your thoughts on it, is it a better or worse MU for Reimu than her vs Puyo Puyo gal?
Reimu vs Sailor Mars
Connections: They’re both shrine maidens who work at their respective shrines (the Hakurei Shrine for Reimu and the Hikawa Shrine for Rei Hino) from magical girl series who've inherited spiritual powers from their roles and have a red-white color scheme. Both have ofudas (basically charms, wards or scriptures that are said to bear good luck) that they use to disable beings who have an evil aura surrounding them (Reimu's ofudas works on youkai who have an evil aura and Rei’s ofudas purifies enemies of evil influence). Of course as shrine maidens, they can both perform exorcisms and blessings. They both have pets at the shrine who aided them in battle but were subsequently no longer needed again due to both Reimu and Rei perfecting their abilities (Genjii had Reimu hop on his back and aided her to fly up in the PC-98 era up until Windows before she learned on her own, while Phobos and Deimos gave Rei the Mars crystal allowing her to transform into Sailor Mars). Both of them have crystal like subtances that are spiritual in nature that they use as their primary weapon (the Ying-Yang Orb is made out of a type of crystal that have spiritual power and Sailor Crystals are star seeds which are the souls of humans). And it should be noted that this type of weaponry is the only real way of dealing damage to their world’s enemies due to their normal shrine maiden abilities being pretty much ineffective (Reimu against other youkais in the PC-98 era and Mars against Pallapalla and Tiger’s Eye in the house of mirrors). Both of their names have an etymology with a part of their names being "Rei" meaning "lovely" and "beautiful" alongside "spirit" and "soul", basically tying in with them being shrine maidens since priestesses usually have those characteristics alongside them having spiritual powers. Both of them were given their respective roles to ensure they protect their worlds from anything that threatens peace (Reimu having been given the task of exteriminating youkais who threaten the peace of Gensokyo and Sailor Guardians protecting the Earth from evil). Also, with this role they were also given another role to protect something that ensures peace in society (the Great Hakurei Border for Reimu and Princess Serenity for Rei).
