Described at first as 'the type of person that doesn't help other people',even Emporio tells F.F. that 'if Weather Report wasn't there to keep him calm, there is no knowing what Anasui would do'.[6]

After meeting Jolyne, she becomes the target of his romantic obsession, despite the two of them having never formally met. Despite her lack of interest, he is singleminded in his pursuit of her hand in marriage. When they aren't in danger, he'll use anything in his arsenal to woo Jolyne—though he isn't successful and it's frequently used as a source of comic relief. Once he realizes that Jolyne is in danger, he will jump into the fray with little regard for his own safety. In love with the concept of her courageous and burning determination, Anasui mused that given the chance, he would follow Jolyne for eternity.

He will treat anyone who isn't Jolyne badly; the mask of his 'noble' and 'protective' persona thinning to reveal his menacing and intimidating tendencies. Whether friend or foe, Anasui won't hesitate to kill anyone who disturbs his imaginary happiness with Jolyne
