A complete ooc joui war Ginzura head cannons:
• They bathe together with an excuse that they were just "conserving water" (ik rivers also exist at that time but let's just say that it's scarce or contaminated so they wash using collected rainwater instead)
• They sharpen each other's sword (no euphemism included)
• They sneak kisses before charging to the battlefield (yeah, this sounds kinda sappy)
• Katsura usually talks nonsense when he's drunk and then there's that one time that he provoked Gintoki to release the demon within him and go Shiroyasha... in bed. (What kind of nonsense am I typing)
• During a near death scenario (that usually happens always), Gintoki bites Katsura’s ring finger as a permanent marriage ring and Zura does the same. From then on, they were engaged via unsanitary bite marks
