Kasei is only wary of his home territory, the depths. Respectful to other's turf โhe treats Cotton kindly, until something of his is taken. He brings the other great beast gifts from below, hopeful to stay at a truce.
Cotton is wary of the other dragon like/dragon adjacent being. But will tolerate Kasei if that one isn't aggressive to them or any humanoids they live around of.
Randall being quite hyperactive as he always is, is absolutely oblivious to the fact that Kasei clearly does get uncomfortable with his behaviour. But never the less, it's one of the only ways Randall knows how to show his affection.
