2/4 of the set.

Look carefully and maybe even squint a little and you'll spot our teeny-tiny know-it-all Camissun! Paired with Materasu on their journey across the vast land of Nippon, Camissun seeks to learn each of the celestial brush techniques and also comes in handy, sharing his knowledge with the daft deity.

Well that's half of them down, maybe you can guess the other two, maybe you're perplexed, maybe you'll go get a beer. Who knows? maybe even I don't!
