What Okita Sougo and Hijikata Toushiro see when they look at each other is Mitsuba's face.
With summer comes festivals, and with festivals come romance. Seo and Wakamatsu know that. (based on anime ending where all our main couples are horsing around at the matsuri)

Takasugi Shinsuke gets to know one Tokugawa Soyo. Or, one of the ways life could go when two warped young minds meet. [Gintama 3Z verse that transitions into a modern AU. Rated M largely for language and descriptions of violence, brief lemons near the end. Trigger warnings for arson and suicide.]
The flower in his past is dainty and white, the one in his body monstrous and black – and the flowers he will raise are all the various shades of red. Takasugi ft. Joui War flashbacks and the link between beauty and death. I don't know either.
