I'd like for Hijikata do meet Allura again! I feel like these two will keep getting sidetracked a lot due to their different experiences and priorities, which is hilarious to me, but also it would be neat if she got to see that he's actually a capable samurai and not just a total mayonnaise freak (though he definitely is that too).

Also he'll be completely "???" at her balmera familiar, so I'd love to have him encounter it one of these days when you're back in action!
