I don't know why but for fun if your favorite media is made by Funamusea in an alternative universe, how different would it's stories and lore (and maybe characters) if Funamusea wrote them.

If Funamusea created Touhou, like to imagine Remilia Scarlet is always invited by Satanic's Devil Parties despite not being one like Vicers since he is invited for looking like a devil despite being a vampire like Remilia. Also, she brings Flandre after eosd so she can meet the other devils (and possibly torment Ivlis).
