Brief Personality description: Aka is rather shy and easily flustered, but typically has a neutral expression or a gentle smile. Sen is easy-going but a bit devious and sly, usually smirking.
Etc: I have a stash link here with background ideas, although they're rather detailed. I'm ok with heavily simplifying them or just doing something else that's Japanese-inspired.
Aka has essentially normal human traits, but Sen has slit pupils, claws, and elongated fangs. Not sure if you need their heights, but Aka is 5'4" and Sen is 6'3".
